甲胺可用于制造农药、医药、橡胶硫化促进剂、染料、炸药、皮革、石油、表面活性剂、离子交换树脂、脱漆剂、涂料以及添加剂等,是制造农药乐果、西维因、杀虫脒的重要原料。
Methylamine is an important kind of fatty amines organic chemicals and is used in a variety of industries such as manufacture of dyestuffs, treatment of cellulose, acetate rayon, as fuel additive, rocket propellant, and leather tanning processes. It can be used in the synthesis of the N-methyl-chloroacetamide that is the intermediate of the organic phosphorus insecticide dimethoate and omethoate; synthesis of the intermediate of the monocrotophos, α-chloro acetoacetyl methylamine; synthesis of the intermediates of carbamate pesticide, carbamoyl chloride and methyl isocyanate; as well as the synthesis of other pesticides varieties such as formamidine, amitraz, and tribenuron, etc. In addition, it can also be used in medicine, rubber, dyes, leather industry and photosensitive materials.
