| titleOfInvention | For the method for methylbenzene methanol side chain alkylation preparation of styrene |
| abstract | The present invention relates to a kind of method for methylbenzene methanol side chain alkylation preparation of styrene, mainly solve in prior art and there is the low problem low with ethylbenzene selectivity of styrene of toluene conversion.The present invention is by adopting with toluene and methyl alcohol for raw material, and be 0.8 ~ 5: 1 at toluene and methanol molar ratio, temperature of reaction is 350 ~ 450 DEG C, and reaction pressure is 0.08 ~ 0.15MPa, and raw materials quality air speed is 1 ~ 5 hourn -1 condition under, raw material and catalyst exposure, reaction generates ethylbenzene and vinylbenzene, wherein used catalyst makes carrier with alkaline molecular sieve, the at least one be selected from basic metal solves this problem with at least one be selected from alkaline-earth metal preferably to the technical scheme that molecular sieve carries out exchanging modification, can be used in the cinnamic industrial production of methylbenzene methanol side chain alkylation ethylbenzene. |
