标题 :Improved esterification of oxyhydrocarbon polyols and ethers thereof, and products therefrom
发明人：MILSTEIN NORMAN
权利人:HENKEL CORP
摘要:Conducting esterifications of oxyhydrocarbon polyols and their ethers in the presence of a reducing agent, or pretreatment of these materials with a reducing agent allows the synthesis of light colored ester products without bleaching. This method is particularly useful in connection with preparation of fatty acid esters of sorbitan from sorbitol when cyclization of the sorbitol precedes esterification, and the yield in the latter process can be improved by esterification at atmospheric pressure. The method is also particularly useful in synthesis of fatty acid esters of alkyl glucosides, and the results of the latter process can be improved by transesterification with fatty acid esters of lower alcohols catalyzed at temperatures at or below 180 DEG C by hypophosphite ions.
