Abstract

The invention provides an alkyl glycoside sulfobetaine type ampholytic surfactant and a preparation method thereof. The invention also provides the preparation method of the alkyl glycoside sulfobetaine ampholytic surfactant, wherein the preparation method comprises the steps: adding long-chain alkyl polyglucoside into acetone, dropwise adding sulfonyl chloride, carrying out a reaction, dropwise adding diethylamine, carrying out a reaction, adding a sodium bromoethylsulfonate aqueous solution, carrying out a reaction, carrying out vacuum reflux, and desalting to obtain the alkyl glycoside sulfobetaine ampholytic surfactant. The prepared alkyl glycoside sulfobetaine type ampholytic surfactant has the advantages of greenness, natural, low toxicity, low irritation and the like of original long-chain alkyl polyglucoside; meanwhile, the alkyl glycoside sulfobetaine ampholytic surfactant has the advantages of good solubility, good foam stability and the like of a zwitterionic surfactant, theapplication range of the alkyl glycoside sulfobetaine ampholytic surfactant is widened, and the prepared alkyl glycoside sulfobetaine ampholytic surfactant is good in surface activity, foamability and foam stability.

Description

technical field [0001] The invention belongs to the technical field of zwitterionic surfactants, and in particular relates to an alkyl glycoside sulfobetaine type amphoteric surfactant and a preparation method thereof. Background technique [0002] Alkyl Polyglycoside (APG for short) is a mixture obtained by catalytic condensation and dehydration of glucose and natural fatty alcohols under acidic conditions. It has the characteristics of both non-ionic and anionic surfactants. It has excellent performance and compatibility, and has little irritation to human skin. It is a non-toxic, biodegradable and relatively environmentally friendly surfactant. The raw material glucoside mainly comes from natural renewable resources such as corn and potato starch, and is not restricted by petroleum resources. It is widely used in daily chemicals, textiles, food processing, pesticides and pharmaceuticals, and oil exploration and other fields. Some properties are not ideal in practical app...
