Methods of production
1. One-step method The second step is to generate methyl formate from carbon monoxide and methanol under the action of sodium methoxide. In the second step, methyl formate was reaminated to formamide under the conditions of 80-100℃ and 0.2-0.6MPa. This method has fewer problems. Formic acid and methanol are first esterified to form methyl formate, and then ammonolysis to form formamide, and then distillation Chemicalbook to separate methanol and impurities to obtain the finished product. This method tends to become obsolete because of its high cost. 3. One-step synthesis of formamide 4 by carbon monoxide and ammonia under the catalytic action of sodium methoxide under high pressure (10-30mpa) and 80-100℃ temperature. Formic acid and urea methods. 5. The new method is formed by the reaction of sodium formate and ammonium salt at a certain temperature and pressure.
APPLICATION
Used as raw material for synthesis of imidazole, pyrimidine, 1,3, 5-triazine, theine, acrylonitrile copolymer spinning, plastic antistatic coating solvent, Used in medicine and pesticide industry
