　　1. When catalyzing the synthesis of methylamine from ammonia and methanol, a vaporized mixture of methanol and ammonia is first prepared. Then, in the reactor, the reaction is carried out by passing it through the catalyst bed at a pressure of about 220 ℃ - about 500 ℃ and atmospheric pressure - about 50 bar.

　　2. The reaction product of ammonia and methanol is a mixture of three amines (monomethylamine, dimethylamine, trimethylamine), as well as water, ammonia, and unreacted methanol.

　　3. Among these products, monomethylamine is the most desired amine in industry. As a raw material, it can be used in medicine, pesticides (such as carbapenem, dimethoate, chlorpyrifos, etc.), dyes (such as alizarin intermediates, anthraquinone intermediates, etc.), fuels (such as hydrogels, monomethylhydrazine, etc.), surfactants, promoters, rubber auxiliaries, photographic chemicals, and solvents.
