The Synthesis Method and Application Range Of Tert-Butylamine
The key of developing rubber accelerator TBBS is preparation of the main raw material of tert-butylamine. Tert-butylamine is an important lower aliphatic amines.Due to the particularity of molecular structure , the synthesis are difficult, and at the same time also limits the development of rubber accelerator TBBS.
Firetly, the synthesis of tert-butylamine following three ways:
1 Tert-Butyl urea water the media Causticization hydrolysis method
2 The isobutylene ammonifying method
3 N-tert-butyl phenethyl amide hydrolysis method
Secondly, the application range of N-tert-butyl
N-tert-butyl is mainly used for the preparation of environmentally friendly rubber accelerator TBBS .The advantages of rubber accelerator TBBS is that in the curing process it does not produce carcinogenic nitrosamines, and has performance of the general sub-sulfonamide accelerator. So it is China's radial tire vigorously production necessary for of raw materials, new technology development of high purity and low cost of tert-butylamine has great practical significance.
