摘要/Abstract

摘要： 聚氧烯醚嵌段聚合物及其硬脂酸酯类表面活性剂作为优良的消泡剂用于抗生素、谷氨酸发酵和其它行业中^[1~4]。作者曾研究过一些聚氧烯甘油的消泡效力^[5~6]。证明以二硬脂酸酯(GPES-2)的消泡效力最高^[7]。本文研究的是GPE和GPES-2分子中亲水基(聚氧乙烯基,EO)的含量及亲水亲油平衡值(HLB)与消泡效力的关系。

关键词: 消泡, 聚氧烯醚, 聚氧烯醚-硬脂酸酯

Abstract: The antifoaming effects of some polyoxyalkylene glycerol ethers (GPE) and their distearate (GPES-2) are studied. The best results are achieved by GPEwith hydrophibic groups of mol. Wt. 3500~4000 and 10% hydrophilic group content and HLB 0.8~1.5.The antifoaming effects of GPES-2 is higher than those of GPE. GPES-2 with 15~20% hydrophilic group content results in the highest antifoaming effects.

Key words: Antifoaming, Polyoxyalkylene ethers, Polyoxyalkylene stearate
