The experiments were conducted at temperatures from 313.2 K to 343.2 K and the molar ratios of feed (methanol to acid) at 15 and 20. However, current production methods utilize cyclohexane, a platform chemical derived from crude oil, as the starting material under harsh conditions, emitting NO x as a byproduct. DMT and 1,4-butanediol are also reacted to form their polyester (plus methanol ). Find here Adipic Acid, 124-04-9. manufacturers, suppliers & exporters in India. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Hazardous to the aquatic environment (acute / short-term) Reason for no classification: data conclusive but not sufficient for classification Hazardous to the aquatic environment (long-term) TFDCA is produced industrially from the reaction of adipic acid with thionyl chloride (Zhi et al., 2014; Yang et al., 2014). Adipic Acid is available in the form of white crystalline powder (density of untamped powder: 0.63 - 0.65 g/cm³).

Adipic acid (AA) CAS-No 124-04-9 . Persistence and degradability Adipic Acid (ADIPC) (124-04-9) Persistence and degradability Not established. Chemicals for Science Education. 2,5-Thiophendicarboxylic acid (TFDCA) is an interesting biobased building block for the preparation of biobased polymers. Benzene is hydrogenated using Ni-Al 2 O 3 catalyst at 370–800 psi to cyclohexane.
