摘要
以甲缩醛为桥联剂，自制305有机酸为催化剂，进行了2246合成新工艺研究，优化的反应条件为常压，60～80℃，反应时间5h，对甲酚／甲缩醛摩尔比4．5～6．3。
The catalytic synthesis of 2246 using methylal as a methylenebis agent and 305 organic acid as a catalyst was studied. The results showed that 305 organic acid has good activity and high selectivity.The optimized reaction conditions was as follows: reaction temperature 60～80℃, reaction time 5hours, p - cresol/methylal molar ratio 4. 5～6. 3.
