Embodiment 1

[0026] Weigh 240 mg of tea saponin, put it into the reaction flask, add 12 ml of ethyl acetate and stir, add 120 mg of benzyl chloromethyl ether, stir for 1 minute and then add 120 mg of N,N'-diisopropylethylamine . The reaction was stirred at 50°C for 1 hour. After the reaction, the solid product was obtained by filtration. The solid was filtered to obtain a yellow-brown solid powdery benzyloxymethyl ether type modified tea saponin surfactant.

Embodiment 2

[0028] Weigh 120 mg of tea saponin, put it into the reaction flask, add 6 ml of ethyl acetate and stir, add 90 mg of benzyl chloromethyl ether, stir for 1 minute and then add 90 mg of N,N'-diisopropylethylamine . The reaction was stirred at 50°C for 1 hour. After the reaction, the solid product was obtained by filtration. The solid was filtered to obtain a yellow-brown solid powdery benzyloxymethyl ether type modified tea saponin surfactant.

Embodiment 3

[0030] Weigh 120 mg of tea saponin, put it into the reaction flask, add 6 ml of ethyl acetate and stir, add 120 mg of benzyl chloromethyl ether, stir for 1 minute and then add 120 mg of N,N'-diisopropylethylamine . The reaction was stirred at 50°C for 1 hour. After the reaction, the solid product was obtained by filtration. The solid was filtered to obtain a yellow-brown solid powdery benzyloxymethyl ether type modified tea saponin surfactant.

Abstract

The invention discloses a preparation method of a benzyl oxymethyl ether type modified tea saponin surfactant, comprising: adding an acid-binding agent, tea saponin and benzyl chloromethyl ether into an organic solvent, and carrying out non-toxic Homogeneous etherification reaction; post-treatment to obtain benzyloxymethyl ether type modified tea saponin surfactant. The present invention also provides a surfactant prepared by the above preparation method. The preparation process of the invention is simple and environment-friendly, and the benzyloxymethyl ether type modified tea saponin surfactant prepared by the method has better surface activity and foaming property, and has better market prospect.

Description

Technical field [0001] The invention relates to the technical field of surfactant preparation, in particular to a preparation method and product of a benzyloxymethyl ether type modified tea saponin surfactant. Background technique [0002] Tea saponin, also known as tea saponins, is a type of oleanane-type pentacyclic triterpene saponins compound. It consists of saponins, sugar bodies and organic acids. It is widely found in the roots, stems, leaves, and Flowers and fruits. Tea saponin is a natural surfactant with good performance. It can be widely used in light industry, chemicals, pesticides, feed, aquaculture, textiles, oil extraction, mining, building materials and highway construction and other fields, used to make emulsifiers, Detergents, pesticide auxiliaries, feed additives, crab and shrimp breeding protective agents, textile auxiliaries, oil field foaming agents, mining flotation agents, aerated concrete foam stabilizers and concrete admixtures-antifreeze, etc. The out...
