| titleOfInvention | The method of methanol and benzene alkylation dimethylbenzene |
| abstract | The present invention relates to a kind of method of methanol and benzene alkylation dimethylbenzene, mainly solve that raw material sources in the prior art are single or methanol introduction volume is few, reaction waste contains methanol, conversion per pass is low, the problem of methylating selectively low.The present invention makes methanol first be converted into dimethyl ether by using two-step process, then reaction temperature be 250 500 DEG C, the 3.0MPa of reaction pressure 0.1, air speed be 0.3 10.0h ‑1 Under conditions of, contacted after dimethyl ether and benzene mixing with molecular sieve catalyst, occur alkylated reaction generation dimethylbenzene, the problem is preferably solved, in the industrial production that can be used for dimethylbenzene. |
