Method for visible light driven green synthesis of benzoin bis-ether
-
Paragraph 0022-0029, (2019/02/10)
The invention relates to a method for visible light driven green synthesis of benzoin bis-ether. The method comprises the steps that an alkyne compound, an alcohol compound and 10-methyl-9-sym-trimethylbenzene based acridine perchlorate perform driving reaction in the atmosphere at room temperature with the visible light with the wavelength of 450-460 nm, a reaction solution is obtained after 3 hours and is spin-dried to obtain concentrate, and the concentrate is subjected to column chromatography on silica gel to obtain the benzoin bis-ether. The method is high in yield, moderate in conditionand small in environmental pollution.

The present invention discloses a benzoin dimethyl ether synthesis process, which comprises: adding methanol, benzaldehyde, sodium cyanide and water to a reaction kettle, carrying out a condensation reaction to generate an intermediate benzoin, adding the benzoin to an oxidation kettle, carrying out an oxidation reaction to obtain dibenzoyl, adding the dibenzoyl to a synthesis kettle, adding dimethyl sulfate and solvents such as dioxane and sodium methoxide, carrying out alkali fusion, adding water after the alkali fusion, carrying out thermal insulation at a temperature of 70 DEG C, carrying out alkali crystal layering, adding water to the crystal layer, carrying out cooling crystal transition, placing into a centrifuge to dewater, carrying out water washing centrifugation to obtain a crude wet product, pouring the crude wet product into a refining kettle, adding methanol through a metering pump, heating to a temperature of 60 DEG C to dissolve, adding active carbon, carrying out decolorization, filtering after the decolorization so as to remove the active carbon, conveying the filtrate into an crystallization kettle, carrying out cooling crystallization for 3 h to obtain a wet fine product, drying the wet fine product through filtration, washing and drying three-in-one equipment to obtain the finished product, and carrying out packaging warehousing. With the synthesis process of the present invention, the effects of low raw material cost, low environmental pollution, and high finished product yield are achieved.
