化学的特性

Adipic acid is a combustible, white, crystalline solid or powder. Odorless.

化学的特性

Adipic acid is a white crystalline solid/granule; its odor has not been characterized. It is stable and incompatible with ammonia and strong oxidizing agents. It may form combustible dust concentrations in air. The likely routes of exposure to workers are by skin contact and inhalation at workplaces. It is used in the manufacture of nylon, plasticizers, urethanes, adhesives, and food additives.

化学的特性

Adipic acid occurs as a white or almost white, odorless nonhygroscopic crystalline powder. The crystal structure of adipic acid is monoclinic holohedral.

化学的特性

Adipic acid, HOCC(CH:04COOH, is also known as hexanedioic acid and 1,4-butanedicarboxylic acid, is a colorless crystalline dicarboxylic acid. It is slightly soluble in water and has a melting point of 152°C. It is used in the manufacture of nylon and urethane rubber.

化学的特性

Adipic acid is the organic compound with the formula (CH2)4(COOH)2. From the industrial perspective, it is the most important dicarboxylic acid: About 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon. Adipic acid otherwise rarely occurs in nature.

化学的特性

Adipic acid is a crystalline powder with practically no odor. It has the lowest acidity of any of the acids commonly used in foods and has excellent buffering capacity in the range of pH 2.5 to 3.0. Like succinic and fumaric acid, adipic acid is practically nonhygroscopic. Its addition to foods imparts a smooth, tart taste. In grape-flavored products, it adds a lingering supplementary flavor and gives an excellent set to food powders containing gelatin. As a result, adipic acid has found a wide number of uses as an accidulant in dry powdered food mixtures, especially in those products having delicate flavors and where addition of tang to the flavor is undesirable.
Its aqueous solutions have the lowest acidity of any of the common food acids. For concentrations from 0.5 to 2.4 g/100 mL, the pH of its solution varies less than half a unit. Hence, it can be used as a buffering agent to maintain acidities within the range of 2.5 to 3.0. This is highly desirable in certain foods, yet the pH is low enough to inhibit the browning of most fruits and other foodstuffs.

物理的性質

Adipic acid is a straight-chain dicarboxylic acid that exists as a white crystalline compound at standard temperature and pressure. Adipic acid is one of the most important industrial chemicals and typically ranks in the top 10 in terms of volume used annually by the chemical industry.

天然物の起源

Reported found as a minor constituent in butter, and has been found in other fats as a product of oxidative rancidity. It also occurs in beet juice, pork fat, guava fruit (Psidium guajava L.), papaya (Carica papaya L.) and raspberry (Rubus idaeus L.).

使用

Adipic acid’s main use is in the production of 6,6 nylon. It is also used in resins, plasticizers, lubricants, polyurethanes, and food additives.

使用

progestin

使用

Adipic Acid is primarily used in the synthesis of nylon. It has been used as a reagent in the solid-state polymerization of nylon analogs.

使用

Adipic Acid is an acidulant and flavoring agent. it is characterized as stable, nonhygroscopic, and slightly soluble, with a water solubility of 1.9 g/100 ml at 20°c. it has a ph of 2.86 at 0.6% usage level at 25°c. it is used in powdered drinks, beverages, gelatin desserts, loz- enges, and canned vegetables. it is also used as a leavening acidulant in baking powder. it can be used as a buffering agent to maintain acidities within a range of ph 2.5–3.0. it is occasionally used in edi- ble oils to prevent rancidity.

調製方法

Adipic acid is prepared by nitric acid oxidation of cyclohexanol or cyclohexanone or a mixture of the two compounds. Recently, oxidation of cyclohexene with 30% aqueous hydrogen peroxide under organic solvent- and halide-free conditions has been proposed as an environmentally friendly alternative for obtaining colorless crystalline adipic acid.

定義

ChEBI: An alpha,omega-dicarboxylic acid that is the 1,4-dicarboxy derivative of butane.

調製方法

Adipic acid can be manufactured using several methods, but the traditional and main route of preparation is by the two-step oxidation of cyclohexane (C6H12). In the first step, cyclohexane is oxidized to cyclohexanone and cyclohexanol with oxygen or air. This occurs at a temperature of approximately 150°C in the presence of cobalt or manganese catalysts. The second oxidation is done with nitric acid and air using copper or vanadium catalysts. In this step, the ring structure is opened and adipic acid and nitrous oxide are formed. Other feedstocks such as benzene and phenol may be use to synthesize adipic acid. Adipic acid production used to be a large emitter of nitrous oxide, a greenhouse gas, but these have been controlled in recent years using pollution abatement technology.

製造方法

Adipic acid is produced from a mixture of cyclohexanol and cyclohexanone called "KA oil", the abbreviation of "ketone-alcohol oil." The KA oil is oxidized with nitric acid to give adipic acid, via a multistep pathway. Early in the reaction the cyclohexanol is converted to the ketone, releasing nitrous acid:
HOC6H11 + HNO3 → OC6H10 + HNO2 + H2O
Among its many reactions, the cyclohexanone is nitrosated, setting the stage for the scission of the C- C bond:
HNO2 + HNO3 → NO+NO3+ H2O
OC6H10 + NO+→ OC6H9-2 - NO + H+
Side products of the method include glutaric and succinic acids.
Related processes start from cyclohexanol, which is obtained from the hydrogenation of phenol.

反応性

Adipic acid is a dibasic acid (can be deprotonated twice). Its pKa's are 4.41 and 5.41.
With the carboxylate groups separated by four methylene groups, adipic acid is suited for intramolecular condensation reactions. Upon treatment with barium hydroxide at elevated temperatures, it undergoes ketonization to give cyclopentanone.

Biotechnological Production

Adipic acid is industrially produced by chemical synthesis. However, there are new efforts to develop an adipic acid production process using biorenewable sources. A direct biosynthesis route has not yet been reported. The possible precursors Z,Z-muconic acid and glucaric acid can be produced biotechnologically by fermentation. Z,Z-muconic acid can be made from benzoate with concentrations up to 130 mM with a yield of close to 100 % (mol/mol) by Pseudomonas putida KT2440-JD1 grown on glucose. Alternatively, it can be produced by engineered E. coli directly from glucose at up to 260 mM with a yield of 0.2 mol Z,Zmuconic acid per mole glucose .
The production of the second possible precursor, glucaric acid, by engineered E. coli growing on glucose has been reported. However, the product titers were low (e.g. 4.8 and 12 mM. To overcome the problem of low product concentrations, an alternative synthetic pathway has been suggested but not yet demonstrated .
In a hydrogenation process, Z,Z-muconic acid and glucaric acid could be converted chemically into adipic acid. Therefore, bimetallic nanoparticles or platinum on activated carbon as catalysts have been studied . In particular, nanoparticles of Ru10Pt2 anchored within pores of mesoporous silica showed high selectivity and conversion rates, greater than 0.90 mol adipic acid per mole Z,Zmuconicacid. With platinum on activated carbon, conversion rates of 0.97 mol.mol-1 of Z,Z-muconic acid into adipic acid have been shown. Another possibility would be the production of adipic acid from glucose via the a–aminoadipate pathway ]. Finally, the production of adipic acid from longchain carbon substrates has been suggested. The conversion of fatty acids into dicarboxylic acids by engineered yeast strains has been reported.

一般的な説明

Adipic acid is a white crystalline solid. Adipic acid is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Adipic acid is used to make plastics and foams and for other uses.

空気と水の反応

Dust may form explosive mixture with air [USCG, 1999]. Insoluble in water.

反応プロフィール

Adipic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in Adipic acid to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions. Behavior in Fire: Melts and may decompose to give volatile acidic vapors of valeric acid and other substances.

健康ハザード

Inhalation of vapor irritates mucous membranes of the nose and lungs, causing coughing and sneezing. Contact with liquid irritates eyes and has a pronounced drying effect on the skin; may produce dermatitis.

健康ハザード

Exposures to adipic acid cause pain, redness of the skin and eyes, tearing or lacrimation. Adipic acid has been reported as a non-toxic chemical. Excessive concentrations of adipic acid dust are known to cause moderate eye irritation, irritation to the skin, and dermatitis.It may be harmful if swallowed or inhaled. It causes respiratory tract irritation with symptoms of coughing, sneezing, and blood-tinged mucous.

火災危険

Behavior in Fire: Melts and may decompose to give volatile acidic vapors of valeric acid and other substances. Dust may form explosive mixture with air.

応用例(製薬)

Adipic acid is used as an acidifying and buffering agent in intramuscular, intravenous and vaginal formulations. It is also used in food products as a leavening, pH-controlling, or flavoring agent.
Adipic acid has been incorporated into controlled-release formulation matrix tablets to obtain pH-independent release for both weakly basicand weakly acidic drugs.It has also been incorporated into the polymeric coating of hydrophilic monolithic systems to modulate the intragel pH, resulting in zero-order release of a hydrophilic drug.The disintegration at intestinal pH of the enteric polymer shellac has been reported to improve when adipic acid was used as a pore-forming agent without affecting release in the acidic media.Other controlled-release formulations have included adipic acid with the intention of obtaining a late-burst release profile.
