| titleOfInvention | Method for preparing 2,3-dimethyl-2-butene through isobutene disproportionation |
| abstract | The invention relates to a method for preparing 2,3-dimethyl-2-butene through isobutene disproportionation and mainly solves the problem of low target product selectivity in the prior art. According to the method, isobutene is used as raw materials, and raw materials and catalysts are in contact for reaction to generate effluents containing 2,3-dimethyl-2-butene, i.e. tetramethylethylene in a fixed bed rector under the conditions that the reaction temperature is 350 to 450 DEG C, the reaction pressure is 0.2 to 0.8MPa through be metered by an absolute pressure gauge, and the weight space velocity is 2 to 20 h<-1>, wherein the used catalysts comprise the following ingredients in percentage by weight: a, 2 to 20 percent of tungsten oxide; b, 0.05 to 1 percent of alkaline earth metal oxide; and c, 79 to 97 percent of Al2O3. Through the technical scheme, the problem is perfectly solved, and the method can be used for the industrial production of tetramethylethylene preparation through isobutene disproportionation. |
