非离子表面活性剂十二烷基聚甘油醚的合成与性能研究

Study on the synthesis and properties of nonionic surfactant dodecyl polyglycerol ethers

在碱催化作用下以十二烷基缩水甘油醚(AGE)与聚甘油反应合成了一种非离子表面活性剂十二烷基聚甘油醚,并研究了不同甘油聚合度(n)对产物表面化学性能的影响。结果显示,当n=2时,γcmc和cmc最低;n=10时,泡沫性能、钙皂分散性能和增溶性能最好;n=4时,乳化性能最好。

In the presence of an alkali catalyst, dodecyl polyglycerol ethers have been synthesized by dodecyl glycidyl ether （ AGE ） and polyglycerol. The surface chemical properties of the products were determined ,Tome appears the lowest value at n = 2, and cmc achieves the lowest at n = 2. The foaming power, the dispersing power and the solubilization capacity show the best at n = 10. The emulsifying power shows the best at n = 4.
