Background

The synthesis of nylon is polycondensation reaction, and the equilibrium constant is relatively small. If a polymer with larger molecular weight is desired, a high vacuum is used to remove small molecular byproducts. However, this is likely to cause decarboxylation of the acid. Amine is volatilized under high vacuum condition, which causes loss. This causes the molar ratio of diamine to dibasic acid in the raw material to change. The molar ratio of the raw materials affects the molecular weight of the product and thus the mechanical properties of the final polymer. Therefore, in order to ensure the molar ratio of the raw materials as much as possible, in the production process, diamine and dibasic acid are firstly made into a salt forming form, so that the decarboxylation and volatilization losses are reduced, the molar ratio of the raw materials is ensured, the copolycondensation reaction needs strict equivalent weights of functional groups to be polymerized into macromolecules, and the salt forming is to be made into strict dibasic acid: diamine is 1: 1, and can be purified by recrystallization after salt formation.
