Method for producing high purity isobutene using glycol ether |
abstract |
Process for producing isobutene, which is capable of separating (manufacturing) high purity isobutene from C4 mixture by cracking the C4 mixture comprising isobutene (particularly C4 residue-1) and glycol ether prepared from glycol This is disclosed. The method for preparing isobutene includes 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 prepared by reacting a glycol with a C4 mixture containing isobutene in the presence of an acid catalyst. |
