防老剂RD制备

将苯胺和苯磺酸按质量份数分别为8.9份和0.52份投入设有冷凝器装置的釜式反应器中,搅拌下加热熔融并升温至155℃,开始滴加丙酮,保持温度155~165℃,当加完质量份数13份的丙酮后,仍保持温度155~165℃在丙酮的回流下进行缩合反应,一直到终点。将产物送入蒸馏塔,蒸出水并回收丙酮,再进行减压蒸馏,收集130~140℃(2kPa)沸程的馏分即得单体2,2,4-三甲基-1,2-二氢化喹啉。
在搪瓷反应釜中先加入将8份30%的盐酸,搅拌下加入水稀释至17%左右,加热到80℃,徐徐滴加单体,保持温度95~98℃进行聚合。滴加完单体后,继续反应4h。加入15%的NaOH溶液进行中和,使反应物料呈中性。然后经冷却、结晶、过滤、水洗、干燥,即得成品。
