PROCESS FOR PRODUCING ISOBUTYLENE AND METHANOL |
摘要 |
<p>A process for producing isobutylene and methanol comprising: a first step of subjecting methyl-tert-butyl ether to decomposition in the presence of a catalyst to obtain a reaction liquid; a second step of washing the resultant with water to separate the reaction liquid into an oil layer and an aqueous layer; a third step of subjecting the oil layer to distillation to obtain a fraction containing isobutylene and a dialkyl ether from the top of a distillation column, a fraction containing methyl-tert-butyl ether and the heavy components from the bottom of the column and a fraction containing methyl-tert-butyl ether from a side cut of the column, and recycling the side cut fraction to the first step; and a fourth step of subjecting the aqueous layer to distillation to obtain a fraction containing methanol from the top of a distillation column and a fraction containing water from the bottom of the column.</p> |
