Method for preparing methyl carbazate |
| abstract |
Methyl carbazate which is particularly pure and has a particularly low tendency toward discoloration is obtained from hydrazine and dimethyl carbonate if the two reactants are metered simultaneously into an initially introduced first solvent at from -20 to +30° C., the solvent and low-boiling components are then distilled off under reduced pressure, and then either a second solvent is added to the crude methyl carbazate present and this solvent is distilled off under reduced pressure or an inert gas is passed through the crude methyl carbazate present. |
