It is soluble in water and can be miscible with common organic solvents such as ethanol, ethyl ether, acetone, ethyl acetate, chloroform, heptane, benzene and the like. Cyclohexylamine can be evaporated together with the steam and can absorb the carbon dioxide in the air to form a white crystalline carbonate. It can form azeotrope with water with the co-boiling point being 96.4 ℃ and water content being 55.8%. Its aqueous solution is alkaline. The pH of 0.01% aqueous solution of 0.01% is 10.5. Its steam can form explosive mixture with air. This product is toxic and irritating to the skin and mucous membranes, causing gangrene; inhaling its vapors has a narcotic effect but without causing blood poisoning. Rat oral administration: LD50: 710 mg/kg. The maximal allowable concentration in workplace is 10 × 10-6.
Heating cyclohexylamine together with hydrogen iodide in a sealed tube at 200 ℃ can generate methyl cyclopentane. Heating cyclohexylamine together with dimethyl sulfate in ether generate methyl cyclohexane and a small amount of dimethyl cyclohexylamine as well. Its hydrochloride can have reaction with sodium nitrite salt to generate cyclohexanol. Its reaction with excess amount of ammonia and zinc chloride can generate 2-methyl-pyridine.
Preparation: they finished product of cyclohexylamine can produced through catalyzing the reduction action of aniline at a high temperature and high pressure (with nickel or cobalt as the catalyst); it can also be produced by taking the cyclohexanol and cyclohexanone as the raw material produced from catalytic reduction of phenol, and further go through amination action with ammonia to prepare it. In industry, cyclohexylamine is mainly used as the thiazole vulcanization accelerator of rubber as well as being used as the tank cleaning agent, dyeing auxiliaries and surfactants.

Chemical Properties

Cyclohexylamine is a colorless to yellow liq- uid (amines, primary aromatic). It has an unpleasant fishy odor.

Chemical Properties

Cyclohexylamine is a derivative of ammonia in which one of the hydrogen atoms has been replaced with a six-carbon, saturated ring. It is a very strong base and forms salts with all acids, including carbon dioxide which it rapidly absorbs from the air. It undergoes the usual reaction of aliphatic amines with carbon disulfide to form dithiocarbamates. Cyclohexylamine reacts with long-chain fatty acids to form soaps (Carswell and Morrill 1937). With nitrous acid, it forms cyclohexanol with the release of nitrogen (Schweizer 1978). Cyclohexylamine reacts with organic compounds containing an active halogen atom, acid anhydrides, and alkylene oxides to replace one or both hydrogens on the nitrogen atom.
Cyclohexylamine attacks all copper alloys and lead. When hot, it attacks aluminum very slowly (Carswell et al 1937).


Cyclohexylamine is used in the manufactureof a number of products, including plasticizers, drycleaning soaps, insecticides, andemulsifying agents. It is also used as a cor rosion inhibitor and in organic synthesis.

Production Methods

Cyclohexylamine is produced by the reaction of ammonia and cyclohexanol at elevated temperature and pressure in the presence of a silica-alumina catalyst (SRI 1985). It is also prepared by a similar process of catalytic hydrogenation of aniline at elevated temperature and pressure. Fractionation of the product of this reaction yields CHA, aniline, and a high-boiling residue containing n-phenylcyclohexylamine and dicyclohexylamine (Carswell and Morrill 1937). In 1982, U.S. production was 4.54 metric tons and 739.3 metric tons were imported into the U.S. (SRI 1985).

Professional standards

TWA 40 mg/m3

General Description

A clear colorless to yellow liquid with an odor of ammonia. Flash point 90°F. Irritates the eyes and respiratory system. Skin contact may cause burns. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during combustion.

Air & Water Reactions

Highly flammable. Sensitive to air and light. Soluble in water.

Reactivity Profile

Cyclohexylamine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

This is classified as very toxic -- probable oral lethal dose is 50-500 mg/kg or between 1 teaspoon and 1 ounce for a 70 kg (150 lb.) person. It is considered a nerve poison. This is a weak methemoglobin-forming substance.

Health Hazard

When humans were exposed to a 25% solution of aqueous cyclohexylamine in skin patch tests, irritation was reported as severe and sensitization as slight (Malette and von Haam 1952). Exposure to high concentrations may cause nausea and narcotic effects (Windholz et al 1983). Three cases of transitory systemic toxic effects due to acute accidental industrial exposure have been reported (Watrous and Schultz 1950). Victims reported lightheadedness, drowsiness, anxiety, apprehension and nausea. One person suffered from slurred speech, vomiting and pupillary dilation. Workers exposed to 4 to 10 p.p.m. however, had no negative effects.
Oral administration of cyclohexylamine (5 and 10 mg/kg) to adult male humans caused headache, blurring of vision and shivering in the exposed subjects (Eichelbaum et al 1974).
When cyclohexylamine was administered orally to humans (2.5, 5.0 and 10 mg/kg), a dose-dependent rise in arterial blood pressure was observed (Eichelbaum et al 1974). The investigators calculated that plasma levels of cyclohexylamine of 0.7 to 0.8 μg/ml were required to cause a significant increase. Only the highest dose (11 mg/ml) produced a significant increase in plasma free fatty acids and cumulative excretion of catecholamines. These data suggest that cyclohexylamine is an indirect acting sympathomimetic substance, although of relatively low potency and are in good correlation with results obtained from animal studies (Classen and Marquardt 1969; Rosenblum and Rosenblum 1968a, 1968b; Wechsler et al 1969; Yamamura et al 1968).

Health Hazard

Cyclohexylamine is a severe irritant to theeyes, skin, and respiratory passage. Skincontact can produce burns and sensitization;contact of the pure liquid or its concentratedsolutions with the eyes may cause loss ofvision.
The acute oral and dermal toxicity ofcyclohexylamine was moderate in test sub jects. The toxic effects include nausea, vom iting, and degenerative changes in the brain,liver, and kidney. Inhalation of its vaporsat high concentrations may cause a narcoticeffect.
LD50 value, oral (rats): 156 mg/kg
LD50 value, skin (rabbits): 277 mg/klg
Cyclohexylamine may be mutagenic, thetest for which has so far given inconclusiveresults. Administration of this compoundin animals produced a reproductive effect,including embryotoxicity and a reductionin male fertility. Intraperitoneal injectionof the amine in rats caused a dose dependent increase in chromosomal breaks.Roberts and coworkers (1989) studied themetabolism and testicular toxicity of cyclohexylamine (a metabolite of cyclamate)in rats and mice. Chronic dietary administration of 400 mg/kg/day for 13 weeksshowed decrease in organ weigh, histological changes, and testicular atrophy in boththe Wistar and dark agouti DA rats, but to awidely varying extent, while mice exhibitedno evidence of testicular damage.
There is no evidence of carcinogenicityin animals or humans caused by cyclohexy lamine.

Fire Hazard

When heated to decomposition, Cyclohexylamine emits highly toxic fumes. Vapor may travel a considerable distance to source of ignition and flash back. Toxic oxides of nitrogen are produced during combustion. Nitric acid; reacts vigorously with oxiding materials. Stable, avoid physical damage, storage with oxidizing material.

Industrial uses

The primary use of cyclohexylamine is as a corrosion inhibitor in boiler water treatment and in oil field applications (HSDB 1989). It is also a chemical intermediate for rubber processing chemicals, dyes (acid blue 62, former use), cyclamate artificial sweeteners and herbicides and a processing agent for nylon fiber production (SRI 1985). Windholz et al (1983) reports its use in the manufacture of insecticides, plasticizers, emulsifying agents, dry-cleaning soaps, and acid gas absorbents.

Safety Profile

A poison by ingestion, skin contact, and intraperitoneal routes. Experimental teratogenic and reproductive effects. A severe human skin irritant. Can cause dermatitis and convulsions. Human mutation data reported. Questionable carcinogen. Flammable liquid. Dangerous fire hazard when exposed to heat, flame, or oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx.

Potential Exposure

CHA is used in making dyes, chemi- cals, dry cleaning chemicals; insecticides, plasticizers, rub- ber chemicals; and as a chemical intermediate in the production of cyclamate sweeteners. Used in water treat- ment and as a boiler feedwater additive. It is also used in rubber production to retard degradation.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ- ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi- cal attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexpo- sure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.


Cyclamate is metabolized to cyclohexylamine by the gut flora in the rat (Renwick and Williams 1969; Bickel et al 1974; Tesoriero and Roxon 1975) and is excreted in the urine after cyclamate ingestion by rats, rabbits, dogs, monkeys, and humans (Asahina et al 1971; Coulston et al 1977; Kojima and Ichibagase 1968; Leahy et al 1967; Oser et al 1968). There is individual variation in the ability to biotransform cyclamate to cyclohexylamine, probably due to the presence or absence of the necessary bacteria. Bacteria exposed to cyclamate seem to acquire the ability to convert cyclamate. Those individuals that do produce cyclohexylamine have been categorized by researchers as convertors. Rhesus monkeys fed cyclamate for eight years converted 0.5% of the dose to cyclohexylamine which in turn was metabolized to cyclohexanone and cyclohexanol to the extent of 1-2% (Coulston et al 1977).
Generally, cyclohexylamine is readily absorbed and rapidly excreted from the body. After administration to rats, cyclohexylamine appears in body tissues with the highest concentrations in the lungs, spleen, liver, adrenals, heart, gastrointes- tinal tract and kidneys (Estep and Wiegand 1967 as reported by Bopp et al 1986).
After oral administration (0.2 g/kg) to rabbits, cyclohexylamine gave rise to unchanged cyclohexylamine and 7V-hydroxycyclohexylamine in the urine (Elliott et al 1968). When [14C]-labelled cyclohexylamine was administered, 68% of the radioactivity was recovered in the urine after 60 h. A small amount (0.5%) was eliminated in the breath and 45% of the administered dose was shown to be excreted in the urine as unconjugated cyclohexylamine, 0.2% as JV-hydroxycyclohexylamine in conjugated form, and 2.5% as cyclohexanone oxime. The authors postulated the latter metabolite to be an artifact formed from the glucuronide of TV-hydroxy cyclohexylamine during the hydrolysis procedure.
In contrast to rabbits, man, as well as rats and guinea pigs, excrete 90% or more of a dose of [14C]-labelled cyclohexylamine unchanged in the urine (Renwick and Williams 1972). Small amounts of radioactivity were found in the feces, 1% or less in man, rat and rabbit, and 4-7% in the guinea pig. Only 4-5% of the dose was metabolized in 24 h in the rat and guinea pig and 1-2% in man. The metabolites identified indicated that in rats, the metabolism of cyclohexylamine was mainly through hydroxylation of the cyclohexane ring, in man by deamination and in guinea pigs and rabbits by ring hydroxylation and deamination. The metabolites to cyclohexylamine were excreted in both free and conjugated forms.
When cyclohexylamine was administered orally to healthy adult humans at doses of 2.5, 5, and 10 mg/kg body weight, 86-95% of the dose was excreted in the urine in 48 h as unchanged cyclohexylamine (Eichelbaum et al 1974). Dose dependency was shown by the plasma half-lives which ranged from 3.5 to 4.8 h. A study by Roberts and Renwick (1985) showed other species and strain differences in metabolism of cyclohexylamine. After administration of [14C]- cyclohexylamine (35-500 mg/kg) to male mice and rats, 80% of the dose was excreted in the urine 24 h after dosing. In Wistar rats, 14-19% of the 14C was present as 3- and 4-aminocyclohexanols, while in the DA strain rat, aminocyclohexanols accounted for only 1-2% of the activity, and in mouse, <1%. Dose or route of administration did not significantly affect metabolism.
When [14C]-cyclohexylamine hydrochloride was administered to pregnant rhesus monkeys by infusion into the antecubital vein, maternal and fetal levels of radioactivity were virtually identical over a period of 6 h (Pitkin et al 1969) indicating that cyclohexylamine freely crosses the hemochorial placenta.
Rabbit liver microsomes have been shown to deaminate cyclohexylamine to cyclohexanone in the presence of NADPH and molecular oxygen (Kurebayashi et al 1979). The hexanone was then reduced to the alcohol (approximately 75% of the deaminated product). Carbon monoxide, SKF 525A, metyrapone, potassium cyanide and mercuric chloride inhibited the deamination. These results suggest that the deamination is catalyzed by a microsomal cytochrome P-450 monooxygenase system.
