Method for coproducing isobutene and ETBE from tert-Butanol mixture |
| abstract |
This invention describes a method for co-producing isobutene and ethyl tert-butyl ether from tert-butanol mixture in a catalytic distillation column, wherein catalyzing the tert-butanol mixture with the ethanol undergoes dehydration and etherification. The tert-butanol mixture contains absolute ethanol or aqueous ethanol as the antifreeze agent. The isobutene and the ethyl tert-butyl ether withdrawn from the column top are further separated, thus high purity isobutene and ethyl tert-butyl ether for fuel-additive are obtained. |
