SEPARATION OF N-METHYLETHYLENEDIAMINE FROM EDA-CONTAINING MIXTURES
摘要:
A process for producing EDA from a mixture comprising water (H2O), ethylenediamine (EDA) and N-methylethylenediamine (NMEDA) by feeding the mixture into a rectification column, wherein the rectification column is operated at the top pressure in the range of 5.0 to 7.5 bar.
