Embodiment

[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...

Abstract

The invention relates to a method for preparing methyl heteroside polyether fatty acid ester derivate. Wherein, it comprises following three steps: 1, using methyl heteroside as material, adds alkali catalyst and phase-shift catalyst, adds epoxyethane or epoxypropane to obtain the methyl heteroside polyether; 2, adding methyl heteroside polyether and fatty acid into reaction kettle, adding composite alkali catalyst, to obtain the rough product of methyl heteroside polyether fatty acid ester and relative derivate; 3, using acid to neutralize the methyl heteroside polyether fatty acid ester and relative derivate, adding alcohol as solvent, using active carbon to decolourize, using bergmeal to filter, to obtain the final products.

Description

technical field [0001] The invention relates to a preparation method of a surfactant, in particular to a preparation method of methyl glucoside polyether fatty acid ester series derivatives. Background technique [0002] The surfactant produced from methyl glucoside is natural, mild and easy to biodegrade, and can be compounded with various raw materials. It is widely used in daily chemical, food, textile and other industries. (120) Thickeners such as dioleic acid esters have the remarkable advantage that the viscosity of the thickening system hardly changes with temperature, and are mild in nature and less irritating, and are often used in personal care products. At present, the domestically produced methyl glucoside series derivative products have always had poor appearance, poor performance and unstable quality, which are greatly restricted in market promotion and product application. Contents of the invention [0003] The invention mainly solves the technical problems...
