| Abstract: | The synthesis of polyether type defoamer agent and its application to the process water in the ethylene device are reported. The defoamer of glycerin polyoxyethylene and polyoxypropene stearic ester was synthesized with acid as catalyst and toluene as solvent through azeotropic dehydration and esterification method. The optimum technical conditions were obtained by discussing how the material ratio, reaction temperature and time affect on defoaming rate. The results of lab and pilot experiments show that the synthesis process is very stable and defoaming property of the product is very good. |
