Embodiment

[0013] Example: Using methyl glucoside as the starting material, adding catalyst sodium methoxide and phase transfer catalytic assistant to modify glycerin, adding ethylene oxide or propylene oxide, and initiating the reaction at 120 ° C, by controlling the reaction temperature until the pressure reaches In addition; control the reaction temperature at 150°C, and continuously add ethylene oxide to react for 90 minutes to obtain the crude product of methyl glucoside polyether; neutralize the crude product of methyl glucoside polyether with oxalic acid to pH=6.0, Add ethanol as a solvent, use activated carbon to decolorize, the decolorization time is 6 hours, and the decolorization temperature is 110°C; under the condition of 110°C, use diatomite filter aid, use cotton filter cloth and filter paper as filter material, so that the filtration speed reaches And keep it at 250Kg / hour to get the methyl glucoside polyether product.

Abstract

The invention relates to the making of surface activator methylglucoside polymer series product, starting with the methylglucoside, adding basic catalyst and moving catalyst, putting into epoxyethane or epoxypropane, reacting within 50deg.C-150deg.C, controlling temperature and pressure to zero through heat transfer rate, controlling temperature within 50deg.C- 200deg.C for 30-120 minutes to get methylglucoside, which is neutralized to PH 5-9, adding alcohol or water as the dilute, using active carbon decoloriation for 2-12 hours in the temperature of 90deg.C- 120deg.C. Under 80deg.C-100deg.C, it is filtered by bergmeal in the speed of 200-300Kg / hour to get the final product.

Description

technical field [0001] The invention relates to a preparation method of a surfactant, in particular to a preparation method of a series of methyl glucoside polyether products. Background technique [0002] The surfactant produced from methyl glucoside is natural, mild, easy to biodegrade, can be compounded with various raw materials, and is widely used in daily chemical, food and other industries. Moisturizers such as methyl glucoside polyoxyethylene (20) ether have the remarkable advantages of being mild in nature, less irritating, and can adjust the viscosity of the shampoo system without reducing the content of active ingredients. Commonly used in personal care products, such as shampoo, shower gel and soap. Domestically, in the manufacture of methyl glucoside polyether series derivatives, the performance cannot meet the application requirements, the quality is unstable, and there are great restrictions on market promotion and product application. Contents of the inven...
