| | A new method of catalystic syntvesis of alkylimidazoline was studied. The influence of ratio of reaction mass, reaction temperature, amount of solvent and catalyst on the product were investigated. The result showed that ratio of lauric acid:hydroxy ethylene diamine is 1:1 (mol),reaction temperature is 150~175C . amount of catalyst active aluminium oxide is 5 grams.amount of solvent dimethylbenzene is 25 ml, yield of alkylimidazoline is 93%-96%,The cationic imidazoline surfactant was synth... | | 研究了烷基咪唑啉的催化合成新方法,探讨了投料比、反应温度、催化剂和溶剂的用量对产物的影响。结果表明,月桂酸:羟乙基乙二胺=1:1(mol比),反应温度150~175℃,催化剂活性氧化铝5g,溶剂二甲苯25ml,烷基咪唑啉产率93%~96%。还合成了咪唑啉阳离子表面活性剂。 | | 文摘来源 | |   |
