Study on the Synthetic Process of Rubber Antioxidant 4020

At present, the domestic mainstream anti-aging agent 4020 production process uses p-aminodiphenylamine and methyl isobutyl ketone as raw materials. Under the pressure of 5-16 MPa, the copper-based catalyst is used for hydrogenation reaction, and the anti-aging agent 4020 is obtained through the post-treatment process. . Although this process is continuous, easy to operate, the catalyst is inexpensive and not easily poisoned, but the product quality is slightly poor and the yield is low. In addition, a small amount of catalyst powder is introduced into the antioxidant 4020, which is applied to the rubber to affect the quality of the rubber product. Most foreign countries use Pt and other precious metals as catalysts, and the quality and yield are better than domestic ones. The sales price has made up for the shortcomings of high catalyst cost. At present, many domestic anti-aging agent 4020 manufacturers are also conducting research on precious metal catalysts, but industrialized devices have not yet been built, which is also the main research direction of anti-aging agent 4020 synthesis. In this paper, through the small test and pilot test, the 4020 process was prepared by reductive amination with Pt as catalyst. Screening out 3% Pt/C from foreign company A can get the product quality we need, after the reaction temperature, pressure and distribution. Compared with optimization, the optimized process conditions are: pressure 1.5Mpa, reaction temperature 110-120 ° C, ratio of RT to MIBK 1:3.5 (molar ratio), reaction time 3 hr. Solve the problems in the debugging process one by one, open up the entire process route, and provide design basis for industrial design.
