Abstract:Fatty acid esters of methyl glucoside was synthesized from methyl glucoside and stearic acid using CT as the catalyst. The influence of the catalyst and temperature on the esterification reaction was reviewed and the products under different reaction conditions were analyzed with IR. The suitable synthesis process was found:n(methyl glucoside) ∶n(stearic acid)=1∶1.4; catalyst of alkali is 0.6% of methyl glucoside(m/m); temperature and pressure of reaction is respectively 150 ℃ and 0.01 MPa.
Key words:methyl glucoside; fatty acid esters; esterification
