AI Technical Summary

Technical Problem

In the existing technology, how to efficiently introduce boron atoms into PEG ester surfactants to improve their stability and antistatic properties has not yet been effectively solved.

Method used

Using polyethylene glycol (PEG), boric acid and fatty acid as raw materials, through esterification reaction under acid catalyzed conditions, PEG is first esterified with boric acid, and then esterified with fatty acid to produce boron-containing polyethylene glycol. Alcohol fatty acid ester surfactant can improve the esterification rate by adjusting the fatty acid type, catalyst and PEG molecular weight.

Benefits of technology

The prepared boron-containing polyethylene glycol fatty acid ester has a high esterification rate, reduces the surface tension of water, shows good emulsification properties, and is suitable for washing, papermaking and other industries.

Abstract

A boron-containing polyethylene glycol fatty acid ester surfactant belongs to the field of organic chemistry and functional materials. The boron-containing polyethylene glycol fatty acid ester surfactant is prepared as follows: polyethylene glycol (PEG), boric acid and fatty acid are used as raw materials, first esterification reaction of the PEG and the boric acid is performed, then esterification reaction of the PEG and the fatty acid is performed to obtain boron-containing poly ethylene glycol fatty acid ester; by changing the species of fatty acids and catalysts and molecular weight of the PEG, the esterification rate can be enhanced, the boron-containing poly ethylene glycol fatty acid ester product can be used as a surfactant, and the boron-containing poly ethylene glycol fatty acid ester can reduce water surface tension and has good emulsifying properties.
