Chemical properties:

N-methylformamide pure product is a colorless, transparent and viscous liquid, m.p.-3.8℃, b.p.198℃, n25D1.43Chemicalbook10, relative density 0.9986 (25℃), soluble in water, and can also dissolve inorganic salts. It has Hygroscopic, easily decomposes in acidic or alkaline solutions.

Usage:

N-methylformamide is an important organic synthetic raw material. It is used in the synthesis of pesticides, insecticides and acaricides monoformamidine and diformamidine. It is also used in the production of medicine, synthetic leather, artificial leather and as a solvent for chemical fiber textiles.

production method

The methylamine method is derived from the interaction between methylamine and carbon monoxide. CO+CH3NH2→HCONHCH3 Supply 87.05kg/ h, while supplying 56.5kg/h of carbon monoxide with a content of 9Chemicalbook9.5%, the reaction temperature is 90°C, and the pressure is 2.53MPa. Take out 140.75kg of the mixture containing 80.5% (mass fraction) of monomethylamine every hour, that is, the production amount of N-methylformamide is 113.4kg per hour, and the production capacity of the 1L reactor is 1.89kg N-methylformamide per hour.
