摘要:以歧化松香醇为原料采用转糖苷法合成了新的非离子表面活性剂松香基聚葡萄糖苷(RPG),研究了丁糖苷的合成反应及苷交换反应。适宜的反应条件为:丁醇与葡萄糖的摩尔比为4∶1,对甲苯磺酸作催化剂,用量为葡萄糖质量的0.5%,生成丁糖苷的温度110℃,苷交换温度140℃,糖转化率达99.5%。研究了产物的表面物理化学性能及环氧乙烷聚合度(n)对产物表面物理化学性能的影响。RPG和RP相比,乳化力(EP)和泡沫性能(FP)有明显的提高。
Rosin-based polyglueoside (RPG), a kind of new nonionie surfactant, was synthesized from disproportionated rosin alcohol polyoxylethene ether (RP) through transacetalization, and reactions including synthesis of butyl polyglycoside and glycoside exchanging were studied. The suitable reaction conditions were obtained as follows : molar ratio of n-butanol to glucose 4 : 1, dosage of catalyst p-toluenesulfonic acid 0. 5 % ( based on glucose mass), reaction temperature for the synthesis of butyl glucoside 110℃, reaction temperature for glycoside exchanging reaction 140 ℃, glucose conversion ratio upto 99. 5 %. Surface physicochemical properties of RP and RPG were measured. Relationships between surface physiochemical properties of the product and polymerization degree (n) of epoxy ethane were studied. Emulsifying power(EP) and foaming power(FP) of RPG were much better than those of RP.
