Etude sur le processus synthétique ya antioxydant ya caoutchouc 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 na société ya bapaya A ekoki kozwa qualité ya produit oyo tozali na yango mposa, sima ya température ya réaction, pression mpe distribution. soki tokokanisi yango na optimisation, ba conditions ya procédé optimisé ezali : pression 1.5MPA, température ya réaction 110-120 degré C, ratio ya RT na MIBK (30 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3 1:3. Solution ya ba problèmes na processus ya débogage moko moko, fungola nzela ya processus mobimba, pe pesa ba bases ya conception pona conception industrielle.
