ABSTRACT:
The separation by conventional distillation or rectification of methyl t-butyl ether from close boiling hydrocarbons is difficult because of the closeness of their vapor pressures. Methyl t-butyl ether can be readily separated from these by extractive distillation. Examples of effective agents are: from 1-pentene, dimethylsulfoxide; from cyclopentane, sulfolane and from n-pentane - cyclopentane mixtures, diethyl malonate.
