[0009] Example: Using methyl glucoside as the starting material, adding catalyst sodium methoxide and phase transfer catalytic assistant modified glycerin, adding ethylene oxide continuously, initiating the reaction at 110°C, controlling the heat transfer rate until the end of the initiating reaction, reducing the Reaction pressure to zero, control the reaction temperature at 150°C, continue to add ethylene oxide to react for 60 minutes to obtain methyl glucoside polyether; put methyl glucoside polyether and stearic acid into the reaction kettle in proportion, add oxidation The mixture of barium and sodium hydroxide was vacuumized and reacted for 10 hours at -0.09MPa and 150°C to obtain the crude product of methyl glucoside polyether stearate; the methyl glucoside polyether fatty acid ester After neutralizing the crude product with acid to a pH of 6, add ethanol as a solvent, and use activated carbon for decolorization. The decolorization time is 6 hours, and the decolorization...
