Process for separation between dialkyl carbonate and alkyl carbamate |
| abstract |
A process for separation between dialkyl carbonate and alkyl carbamate which comprises adding an aromatic hydroxy compound to a liquid comprising alkyl carbamate having an alkyl group having 3 to 6 carbon atoms and dialkyl carbonate having alkyl group having 3 to 6 carbon atoms to obtain a mixed liquid, and distilling the mixed liquid thus obtained in a distillation column to obtain a mixture comprising the dialkyl carbonate and the aromatic hydroxy compound from a top section of the distillation column and a liquid comprising the alkyl carbamate from a bottom section of the distillation column. |
