| titleOfInvention | The technique that after utilizing ether, the C 4 fraction in liquefied gas prepares MTBE |
| abstract | The invention belongs to chemical technology field, be specifically related to a kind of C 4 fraction in liquefied gas after ether for raw material production MTBE(methyl tertiary butyl ether(MTBE)) technique. A kind of utilize ether after C 4 fraction in the liquefied gas technique of preparing MTBE, it is characterized in that, in the synthesizer of MTBE, raw material C4 and methanol enter reactor, under the effect of catalyst, the isobutene. in C4 and methanol generation etherification reaction, generate MTBE, described reaction mass includes the methanol of surplus, C4, product MTBE, by-product dimethyl ether, the C8 tert-butyl alcohol are admitted to azeotrope tower and separate after ether, flow out MTBE crude product bottom azeotrope tower. Adopting the technique that the method for the present invention is raw material production MTBE with the C 4 fraction in liquefied gas after ether, the yield of MTBE can reach 96%. |
