| titleOfInvention | Combined method for preparing methyl tert-butyl ether and isobutylene from tert-butyl alcohol and methanol |
| abstract | A combined method for preparing methyl tert-butyl ether and isobutylene from tert-butyl alcohol and methanol. The method is carried out in a device comprising a catalytic rectification tower. The catalytic rectification tower comprises a catalytic reaction section located at the middle part, tert-butyl alcohol enters the catalytic rectification tower from the catalytic reaction section, and methanol and water enter the catalytic rectification tower from the tower top. In the catalytic reaction section, a part of tert-butyl alcohol is dehydrated to generate isobutylene, and the other part of tert-butyl alcohol and the isobutylene are respectively further reacted with methanol fed from the tower top to generate methyl tert-butyl ether, wherein the tert-butyl alcohol is pretreated, and the molar feeding ratio of tert-butyl alcohol to methanol is 10:1 to 10:9. The combined process combines reaction and separation, promotes the rightward reaction, enables preparation of isobutylene by means of tert-butyl alcohol dehydration and synthesis of MTBE in "one-pot process", greatly simplifies the operation procedure, lowers the process cost and facilitates implementation, and improves the raw material conversion rate overall. |
