摘要
以强酸树脂为催化剂,采用固定床反应器实现连续生产操作。探讨了原料进料方式、反应管内径、丙酮进料流量、苯胺液体空速及强酸树脂种类对橡胶防老剂2,2,4-三甲基-1,2-二氢喹啉聚合物(TMQ)连续生产工艺的影响。经检测,Amberlyst 125上苯胺单程转化率可达74.44%,TMQ收率为47.72%。本研究工艺可实现橡胶防老剂TMQ生产的连续化操作,提高生产效率。
Using strong acid resin as a catalyst,a fixed bed reactor was employed to achieve continuous production operations.The effects of raw material feeding method,reaction tube inner diameter,acetone feeding flow rate,aniline liquid space velocity,and strong acid resin type on the continuous production process of rubber antioxidant 2,2,4-trimethyl-1,2-dihydroquinoline polymer(TMQ)were investigated.The single-pass conversion rate of aniline on Amberlyst 125 reached 74.44%,and the yield of TMQ was 47.72%.The process developed enables continuous operation of rubber antioxidant TMQ production,thereby improving production efficiency.
