Abstract

A new method of synthesizing disodium alkyl polyglucoside citrate surfactant has been reported in the paper, in which citric acid anhydride was firstly prepared, and then reacted with alkyl polyglucoside to obtain ester. The structures of products were indicated by infrared spectroscopy. Moreover, the surface activities of raw materials and their corresponding products were investigated. The results show that products exhibit low surface tension in 28 mN/m. Comparing with raw materials, the disodium alkyl polyglucoside citrate surfactants possess better emulsification stabilities to oil acid, good foam abilities and excellent hard water-resistant properties.

Kurzfassung

Es wird über ein neues Verfahren zur Herstellung von grenzflächenaktivem Dinatrium-alkylpolyglucosid-zitrat berichtet, bei dem zuerst Zitronensäureanhydrid gebildet wird, das dann mit Alkylpolyglucosid zum Ester umgesetzt wird. Die Struktur der Produkte wurde mittels IR-Spektroskopie ermittelt. Weiterhin wurde die Grenzflächenaktivität der eingesetzten Alkylpolyglucoside und deren Zitronensäureester bestimmt. Letztere zeigten niedrige Oberflächenspannungen bis zu 28 mN/m. Die Emulgatoreigenschaften, das Schaumbildungsvermögen und die Hartwasserbeständigkeit der Alkylpolyglucosidzitrate sind besser als die der reinen Alkylpolyglucoside.
