For example, the hydrocarboxylation proceeds as follows: [4]. Adipic acid is produced from the general process of the cleavage of double bonds of alkenes by oxidation to form acids [53]. It is a precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive used in processed meats and (in some countries) in fish products. Cycloheptanone, (CH2)6CO, is a cyclic ketone also referred to as suberone. This colorless oil has an odor reminiscent of that of acetone. Nearly all commercial adipic acid is produced from cyclohexane. Initiation of free radical, Chain propagation, Termination of chain. Its name is derived from caproic acid. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acids. It is the most important of the dicarboxylic acids from the industrial perspective. Cyclohexenone is an organic compound which is a versatile intermediate used in the synthesis of a variety of chemical products such as pharmaceuticals and fragrances. CAS: 124-04-9 Adipic Acid also known as Hexane-1,6-dioic acid is a dibasic acid with the molecular formula C 3 H 8 O 4, CAS 124-04-9. The addition polymerization mainly takes place in free radical mechanism. 1. [4], The production of adipic acid is linked to emissions of N2O, [15] a potent greenhouse gas and cause of stratospheric ozone depletion. Adipic acid has been incorporated into controlled-release tablets to obtain a pH-independent release for both weakly basic and weakly acidic drugs. The pKa values for their successive deprotonations are 4.41 and 5.41. Std. Acidul adipic (nume IUPAC: acid hexandioic) este un compus organic din clasa acizilor dicarboxilici cu formula HOOC-(CH 2) 4-COOH.Din punct de vedere industrial, este cel mai important acid dicarboxilic: aproximativ 2,5 miliarde de kilograme de pudră albă cristalină sunt produse anual, în mare parte pentru utilizarea ca precursor în procesul de producere al nailonului. It is an intermediate in various industrial processes. The majority of the 2.5 billion kg of adipic acid produced annually is used as a monomer for the production of nylon by a polycondensation reaction with hexamethylene diamine forming 6,6-nylon.
