Abstract

The invention discloses a preparation method of methyl formate and belongs to the technical field of ester synthesis. According to the preparation method of the methyl formate, formic acid and methanol can react under the action of solid-phase catalyst to produce the methyl formate. The step of preparing the solid-phase catalyst comprises (a) adding kaolin into deionized water; (b) dissolving aluminum sulfate and copper sulfate into water to obtain solution, immersing the kaolin processed in the step (a) into the solution; (c) mixing cation exchange resin with a substance A and grinding the mixture to obtain a substance B; (d) preparing 30% carborane acid solution, immersing the substance B into the solution and taking the substance B out of the solution, drying the substance B in vacuum, roasting the substance B inside a muffle furnace, and grinding the substance B to obtain the solid-phase catalyst. The preparation method of the methyl formate is non-toxic and harmless, significantly improves the reaction velocity and is low in requirements on reaction conditions and energy consumption, and meanwhile, the catalyst is recyclable, so that the production cost can be effectively reduced, and the preparation method of the methyl formate is applicable to industrial production.

Description

[0001] The present invention is a divisional application for the invention patent of the patent application number: 201410530973.6, the patent name: a preparation method of methyl formate. technical field [0002] The invention belongs to the field of catalysts for synthesis of esters, in particular, relates to a solid-phase catalyst for preparing methyl formate and its preparation method and application. Background technique [0003] Methyl formate, also known as methyl formate, is a colorless, volatile liquid with a scent. Miscible with ethanol, soluble in methanol and ether. It is easily hydrolyzed, and the moisture in the humid air will also cause it to hydrolyze. It has a strong stimulating effect on the respiratory tract, eyes and nose, and can cause chest pressure and dyspnea. Methyl formate is an extremely important intermediate in carbon chemistry and has a wide range of uses. It can be directly used as a fumigant and fungicide for treating tobacco, dried fruits, ...
