PRODUCT INTRODUCTION
description
Adipic acid is a straight chain aliphatic dicarboxylic acid. It is a white crystalline solid, insoluble in water. Adipic acid can be extracted from petrochemicals or synthesised biologically from renewable substrates. Adipic acid is used in the synthesis of nylon and other polyamides.
