Product Applications

It is mainly used for preparing formaldehyde and as methyl agent and solvent in organic synthesis. It is the raw material of methyl tert-butyl ether and can also be used as automobile fuel. It is used as analytical reagent, chromatographic analysis reagent and organic synthesis; used for separation of calcium sulfate and magnesium sulfate, separation of strontium bromide and barium bromide..

Production method

Almost all methanol synthesis in industry adopts the method of pressurized catalytic hydrogenation of carbon monoxide, and the process includes processes such as gasification, synthesis purification, methanol synthesis and crude methanol rectification. The purification process of crude methanol includes distillation and chemical treatment. Chemical treatment mainly uses alkali to destroy impurities that are difficult to separate in the distillation process and adjust the pH value; Distillation is mainly to remove volatile components such as dimethyl ether, as well as non-volatile components, primary ethanol, high carbon alcohol and water. The purity after crude distillation can generally reach more than 98.
