超声波促进的KF-Al_2O_3合成N-十二烷基酰亚胺

Ultrasonically Promoted Synthesis of N-Dodecylimide on Potassium Fluoride-Alumina Catalyst

N -十二烷基 - 1 -异丙基 - 4-甲基二环 [2 ,2 ,2 ]- 5 -辛烯 2 ,3-二甲酰亚胺 (简称 N-十二烷基酰亚胺 )是拟除虫菌酯的增效剂。现以 KF- Al2 O3 作为固体催化剂 ,以 PEG- 60 0作为相转移剂 ,合成N-十二烷基酰亚胺实验结果表明 ,在此条件下 ,反应温和 ,收率高 ,后处理方便。在超声波促进下反应 ,反应速度明显加快 。

N dodecyl 1 isopropyl 4 methylbicyclo[2,2,2] oct 5 ene 2,3 dicarboximide(abbreviation: N Dodecylimide) is a synergist for pyrethroid. N dodecylimide was prepared with potassium fluoride alumina as catalyst and PEG 600 as solid liquid phase transfer catalyst. The experimental results show that the reaction was conducted under mild conditions, and gave a high yield. The reacton rate increased obviously when ultrasonic wave was applied. High yield was acquired even though the reaction temperatuie was reduced.
