Abstract:
with fatty alcohol polyoxyethylene polyoxypropylene ether as raw material, the effects of reaction temperature, reaction time and material ratio on the carboxymethylation reaction were studied, through a series of experiments, the optimum experimental conditions for the synthesis of the lowest interfacial tension system were determined, and the properties of the fatty alcohol polyoxyethylene polyoxypropylene ether carboxylate under the optimum synthesis conditions were discussed, the interfacial tension of fatty alcohol polyoxyethylene polyoxypropylene ether was improved after carboxymethylation.
Key words:
