ENZYME-CATALYZED POLYOXYALKYLENE ESTERS |
摘要 |
One aspect of the present invention is a polyoxyalkylene ester composition comprising the reaction product of a polyoxyalkylated alcohol or polyol reactant and an acyl donor wherein the ester has greater than about 85 weight percent of a fully acylated polyoxyalkylene ester, less than about 15 percent of a partially acylated polyoxyalkylene ester, less than about 5 parts per million 1,4-dioxane and an acid number of less than about 20. Another aspect of the invention is a process for making the polyoxyalkylene ester composition that includes the steps of contacting a reaction mixture of an polyoxyalkylated alcohol or polyol reactant and an acyl donor reactant in a reactor and in the presence of an enzymatic catalyst under esterification conditions and recovering the polyoxyalkylene ester. |
