o-Cresol Chemical Properties,Uses,Production

Chemical Properties

colourless to light yellow liquid

Chemical Properties

Cresol is a mixture of the three isomeric cresols, o-, m-, and p-cresol. Cresols are slightly soluble in water. m-Isomer: Colorless or yellow liquid with characteristic odor.

Chemical Properties

o-Cresol has a musty, phenolic aftertaste.

Occurrence

Reported in Acacial farnesiana, ylang-ylang oil (probably as p-cresyl acetate), jasmine absolute, orange oil from leaves, the essence from flowers of Lilium candidum, anise seed oil, the essence of Artemisia santolinoflia, and some sea algae. Also reported found in asparagus, peppermint oil, cheddar cheese, provolone cheese, butter, milk, lean fish, boiled egg, smoked pork, rum, Scotch whiskey, red wine, white wine, coffee and mango.Reported found in cinnamon, coffee, Oriental tobacco, rum, sherry, tea, tomato and whiskey.

Definition

ChEBI: A cresol that is phenol substituted by a methyl group at position 2. It is a minor urinary metabolite of toluene.

Aroma threshold values

Aroma characteristics at 1.0%: phenolic, medicinal, sweet spicy, smoky with a methyl salicylate nuance.

Taste threshold values

Taste characteristics at 2.0 ppm: sweet medicinal, phenolic and tarlike.

General Description

Colorless or yellow to brown-yellow or pinkish colored liquid with a phenol-like odor. Toxic by ingestion and/or skin absorption. May have a flash point between 100 and 199°F. Causes burns to skin, eyes and mucous membranes. Insoluble in water.

Air & Water Reactions

Sensitive to light and air. Insoluble in water.

Reactivity Profile

o-Cresol is incompatible with oxidizing agents and bases. Mixing o-Cresol with chlorosulfonic acid, nitric acid and oleum in a closed contained caused the temperature and pressure to increase.

Hazard

Questionable carcinogen.

Health Hazard

The chemical is rated as a very toxic compound with a probable oral lethal dose in humans of 50-500 mg/kg, or between 1 teaspoon and 1 ounce for a 70 kg (150 lb.) person. It is a strong dermal irritant and frequently causes dermatitis. Serious or fatal poisoning may result if large areas of skin are wet with cresol, o- and the substance is not removed immediately. Ingestion of even a small amount may cause paralysis and coma. It is corrosive to body tissues, with toxicity similar to phenol.

Fire Hazard

Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. o-Cresol may burn but does not ignite readily. Container may explode in heat of fire. Slight explosion and fire hazard in the form of vapor when exposed to heat or flame. When heated to decomposition, o-Cresol emits highly toxic fumes. Reacts violently with nitric acid, oleum, and chlorosulfonic acid. Hazardous polymerization may not occur.

Safety Profile

Poison by ingestion, inhalation, subcutaneous, intravenous, and intraperitoneal routes. Moderately toxic by skin contact. A severe eye and skin irritant. Human mutation data reported. Questionable carcinogen with experimental neoplastigenic data. Flammable when exposed to heat, flame, or oxidants. To fight fire, water may be used to blanket fire; foam, fog, mist, dry chemical. See also other cresol entries and PHENOL.

Potential Exposure

Cresol is used as a disinfectant and fumigant; as an ore flotation agent, and as an intermediate in the manufacture of chemicals, dyes, plastics, and antioxidants. A mixture of isomers is generally used; the concentrations of the components are determined by the source of the cresol.

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, including 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 medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema Cresols 931 may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy

Shipping

UN2076 Cresols, liquid, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 8-Corrosive material. UN3455 Cresols, solid, Hazard class: 6.1; Labels: 6.1- Poisonous materials, 8-Corrosive material.

Purification Methods

It can be freed from m-and p-isomers by repeated fractional distillation, It crystallises from *benzene by addition of pet ether. It has been fractionallly crystallised by partial freezing of its melt. The 3,5-dinitrobenzoate (prepared with 3,5-dinitrobenzoyl chloride in dry pyridine, and recrystallised from EtOH or aqueous Me2CO) has m 138o. [Beilstein 6 IV 1940.]

Incompatibilities

Vapors may form explosive mixture with air. Incompatible with strong acids; oxidizers, alkalies, aliphatic amines; amides, chlorosulfonic acid; oleum. Decomposes on heating, producing strong acids and bases, causing fire and explosion hazard. Liquid attacks some plastics and rubber. Attacks many metals.

Waste Disposal

Wastewaters may be subjected to biological treatment. Concentrations may be further reduced by ozone treatment. High concentration wastes may be destroyed in special waste incinerators.
