Verfahren zur Herstellung von N,N'-Carbonyldiazolen |
摘要 |
The invention concerns a method for the production of N,N'-carbonyl diazoles by reacting azoles with phosgene in a solvent, wherein the azole and the phosgene are introduced into an aromatic solvent dehydrated by distillation at a doses such that 1 mol azole is introduced at the same time as 01.17 to 0.34 mol of phosgene is dosed. The invention also describes special advantageous possibilities for processing the reaction mixture.
