1、从氨和甲醇催化合成甲胺时，首先制备甲醇和氨的汽化混合物，接下来在反应器中，在大约220℃-约500℃、大气压-约50巴的压力下，通过使其从催化剂床上经过而进行反应。
2、氨和甲醇的反应产物为三种胺（一甲胺、二甲胺、三甲胺）的混合物，以及水、氨和未反应的甲醇组成。
3、在这些产物中，一甲胺是工业上最希望得到的一种胺，其作为原料可用作医药、农药（西维因、乐果、杀虫脒等），染料（茜素中间体、蒽醌系中间体等），及燃料（水胶药、一甲肼等），表面活性剂、促进剂、以及橡胶助剂、 照相化学品和溶剂等。

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.
