Adipic acid or hexanedioic acid is the organic compound with the formula (CH 2) 4 (COOH) 2. From an 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 .
It is the diester of 2-ethylhexanol and adipic acid. It is a colorless oily liquid. DEHA is sometimes called "dioctyl adipate", incorrectly. Another name is di(2-ethylhexyl) adipate. The abbreviation DOA has been unfortunately used for both Bis(-2-ethylhexyl)-adipate and dioctyl adipate

An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Dioctyl adipate (DOA) is an organic compound with the formula (CH 2 CH 2 CO 2 C 8 H 17) 2.It is a colorless oily liquid . As well as related diesters derived from 2-ethylhexanol, decanol, isodecanol, etc., it is used as a plasticizer.
Aliquat 336 is used as a phase transfer catalyst, [2] including in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. [3] This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid. Equivalent amounts of hexamethylenediamine and adipic acid are combined in water. In the original implementation, the resulting ammonium/carboxylate salt was isolated and then heated either in batches or continuously to induce polycondensation.
It is a clear brown liquid. It reacts with water to give adipic acid. It is prepared by treatment of adipic acid with thionyl chloride. [1] Adipoyl chloride reacts with hexamethylenediamine to form nylon 6,6. [2]
