Abstract

The invention relates to the technical field of surfactants, in particular to a glucosamide-terminated polyether surfactant as well as a preparation method and application thereof. The preparation method of the glucosamide-terminated polyether surfactant comprises the following steps: (1) adding glucolactone and polyether amine M2070 into an organic solvent, and heating for reaction to obtain a crude product; and (2) adding the crude product into ethanol, cooling, recrystallizing, and carrying out rotary evaporation treatment to obtain the final product glucosamide-terminated polyether surfactant. The obtained surfactant not only has better surface performance than polyether amine, but also has the characteristics of small irritation to human, easiness in degradation and the like of a glycosyl surfactant, and in addition, the surfactant is relatively simple in synthesis process, relatively high in yield, suitable for industrial production and wide in application prospect.

Description

technical field

[0001] The invention relates to the technical field of surfactants, in particular to a glucamide-terminated polyether surfactant, a preparation method and application thereof. Background technique

[0002] With the development of society and the enhancement of people's awareness of environmental protection, the preparation of green surfactants from natural renewable resources has become a research hotspot. As an amphiphilic polymer compound, polyetheramine surfactants are widely used in the fields of epoxy materials, polyurethane synthesis, and fuel detergents because they contain both amino and ether bond functional groups. However, traditional polyetheramine surfactants have the disadvantages of high critical micelle concentration (cmc) and poor biocompatibility. Contents of the invention

[0003] In order to solve the above-mentioned technical problems, the technical idea of ​​the present invention is: construct the novel glucosamide-terminated polyethe...
