| Abstract: | Polyethylene glycol monomethyl ether(PGME) fatty arid esters were Preped fain methyl fatty acid ester and PGME in the presence of sodium methoxide as catalyst. When a molar ratio of ester to alcohol ether was l: 1. 2, 0. 5% (w) catalyst was used, the mixture was stirred for 6.5h at 120℃, the molar yield of the products based on methyl fatty acid ester can reach 90%. Their structures were confirmed by IR and ~(13)CNMR. The surface active properties of the products were also determined. |
