adipiinihappo

Adipiinihappo, also known as adipic acid, is an organic compound with the formula (CH2)4(COOH)2. It is a dicarboxylic acid, meaning it contains two carboxyl functional groups. Adipiinihappo is a white, crystalline solid at room temperature and is soluble in water and ethanol. It is a naturally occurring substance, though it is produced industrially on a large scale.

The primary industrial application of adipiinihappo is as a precursor in the production of nylon 6,6. This polymer is formed through a condensation reaction between adipiinihappo and hexamethylenediamine. Nylon 6,6 is a versatile material used in a wide range of products, including textiles, carpets, automotive parts, and electrical components. Adipiinihappo is also used in the production of polyurethanes, plasticizers, and lubricants. In the food industry, it can be used as an acidulant and a buffering agent.

The synthesis of adipiinihappo is typically achieved through the oxidation of cyclohexane or cyclohexanol. Several methods exist, including the use of nitric acid as an oxidizing agent. Research continues into more environmentally friendly and efficient methods for its production. Adipiinihappo is generally considered to have low toxicity, but like many organic acids, it can be an irritant in concentrated forms.
