Abstract
After transesterification and neutralization reaction,Stearic glyceride sulfonate is synthesized with alpha-sulfonated stearic methyl ester and glycerol.It is found that the optimum conditions of the transesterification reaction are to use carbon tetrachloride as solvent,w(alpha- sulfonated stearic methyl ester)=22.0%,75 ℃,n(alpha- sulfonated stearic methyl ester)∶(n(glycerol))=(1∶5).and 4h.Under this condition, the conversion of alpha-sulfonated stearic methyl ester is(66.33%).The product is separated by HPLC and the conversion of alpha-sulfonated stearic methyl ester is tested by HPLC.The structure of stearic glyceride sulfonate is confirmed by MS spectra.Finally,it turns out that besides stearic monoglyceride sulfonate,the product also contains stearic methyl ester sulfonate and stearic diglyceride sulfonate.
