PROCESS FOR THE PRODUCTION OF MALONONITRILE |
摘要 |
An improved process for the commercial production of malononitrile by the dehydration of cyanoacetamide employs cyanuric chloride in the presence of a catalytic amount of N,N-dimethylformamide and in a polar solvent that is removed by vacuum distillation at a temperature below 100.degree.C. The N,Ndimethylformamide is added in a molar ratio of 0.16 moles for each mole of cyanoacetamide present in the starting solution.
