摘要
A synthetic process of Disodium of Mono-Alkyl polyoxyethylene Ether Citrate was developed in this paper. The structure of intermediate and products were indicated by infrared spectroscopy. The physico-chemical properties of aqueous solution of products were also investigated. The results show that products are excellent emulsifiers, with the low surface tension in 2730 mN/m and good wetting power, and possess different foaming behavior in hard water and distilled water.
