| titleOfInvention | A kind of method by benzene and methanol alkylation dimethylbenzene |
| abstract | The present invention relates to a kind of method by benzene and methanol alkylation dimethylbenzene, adopt 2 fixed bed alkylation reactors, first reactor is using fresh benzene, recycle benzene and methyl alcohol as raw material, by alkylated reaction preparing methylbenzene and dimethylbenzene, second reactor to adopt in the first reactor reaction product toluene and methyl alcohol as raw material, by alkylated reaction dimethylbenzene.Benzene, toluene are separated with thick dimethylbenzene by 1 benzene toluene separation column by two reactors, isolated Benzene and Toluene circulation, get back to the first reactor and the second reactor respectively as raw material, thick dimethylbenzene isolates Product mix dimethylbenzene and heavy aromatics through xylene distillation tower again.The method of dimethylbenzene processed of the present invention reduces significant loss, improves dimethylbenzene yield, and adopt single tower Separation of Benzene, toluene and thick dimethylbenzene, flow process is shorter, and equipment is simple. |
