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.

Description

technical field [0001] A boron-containing polyethylene glycol fatty acid ester surfactant belongs to the field of organic chemistry and functional materials. Background technique [0002] PEG has excellent properties such as non-toxicity, good stability and easy processing, and is widely used as softener, moisturizer, lubricant, etc. The ester surfactants with PEG as the hydrophilic part are non-ionic surfactants, which have low foam, high stability, and are not easily affected by the presence of strong electrolyte inorganic salts; their emulsifying properties and wetting properties are excellent, and are widely used It is widely used in washing, textile and other industries, and also has important applications in papermaking, construction, agriculture and other fields; existing studies have found that adding a certain amount of PEG ester surfactants to polyolefin plastics can significantly improve the antistatic properties of plastics sex. [0003] Boron is a non-toxic an...
