PROCESS FOR THE DISTILLATIVE SEPARATION OF MIXTURES COMPRISING MONOETHYLENE GLYCOL AND DIETHYLENTRIAMINE |
摘要 |
A process is proposed for the distillative separation of a mixture comprising monoethylene glycol and diethylenetriamine, to form a stream (7) which contains monoethylene glycol and is largely free from diethylenetriamine, and a stream (8) which contains diethylenetriamine and is largely free from monoethylene glycol, the process being characterized in that the separation is carried out by extractive distillation using triethylene glycol as a selective solvent for diethylenetriamine. |
