Monomethylamine, also known as methylamine, aminomethane, is an important organic chemical raw material and intermediate, at room temperature and pressure for the flammable colorless gas, high concentration or compressed liquefaction, has a strong ammonia odor. When the concentration is very low, it has fishy odor. Soluble in water, soluble in ethanol,. Easily combustible, and air to form explosive mixtures, explosion limit: 4.3% ~ 21%. Weakly alkaline, alkaline than ammonia, and inorganic acids to generate easily soluble in water salts. Synthesized by methanol and ammonia under high temperature and pressure and catalyst, it can also be produced by formaldehyde and ammonium chloride when heated to 300℃ under the action of zinc chloride. Methylamine can be used in the production of pesticides, pharmaceuticals, rubber vulcanization accelerator, dyes,, tanning, petroleum, surfactants, ion exchange resins, paint strippers, coatings and additives. It is an important raw material for the production of pesticides, such as Legris, carbaryl and amitraz. The inhalation toxicity of monomethylamine belongs to low toxicity category, air zui high permissible concentration of 5mg/m3 (0.4ppm). It is corrosive and irritates eyes, skin and mucous membranes. When exposed to open flame, high heat may cause combustion hazard, cylinder and accessory damage will cause explosion.

Basic information

Monomethylamine aqueous solution has a wide range of applications in several fields due to its unique properties and application value. The following are its main uses:

Pharmaceuticals: Monomethylamine aqueous solution can be used as intermediates of drugs, involved in the synthesis of many drugs, such as anti-cancer drugs, antibiotics and vitamins.

Pesticides: Monomethylamine aqueous solution can be used in the production of certain pesticides, such as hydrocolloid explosives and monomethylhydrazine, etc. It can also be used as an insecticide.

Dyes: Monomethylamine aqueous solution reacts with dye precursors to produce dyes, which are used in the textile, printing and dyeing industries.

Surfactants and accelerators: monomethylamine can react with fatty acids or alkyl bromides to form quaternary ammonium salts or quaternary ammonium bases, which are often used as surfactants; at the same time, monomethylamine is also used as rubber vulcanization accelerators.

Other chemical products: Monomethylamine aqueous solution is also used in the preparation of photographic chemicals, explosives and other related products.

Agriculture: as a kind of nitrogen fertilizer, monomethylamine aqueous solution can provide the nutrients needed by crops, and can be used as an insecticide to help control pests and diseases.

In summary, monomethylamine aqueous solution not only plays an important role in organic synthesis, medicine, agriculture and chemical industry, but also its application fields are still expanding and developing.
