Method for producing high-purity isobutene using glycol ether |
| abstract |
Production of isobutene capable of separating (manufacturing) high-purity isobutene from C4 mixture by cracking the glycol ether produced from C4 mixture containing isobutene (especially C4 residual oil-1) and glycol A method is disclosed. The method for producing isobutene includes a step of dissociating glycol ether into isobutene and glycol at a temperature of 50 to 300 ° C. in the presence of a strongly acidic catalyst. Here, the glycol ether is preferably produced by reacting glycol with a C4 mixture containing isobutene in the presence of an acid catalyst. |
