| titleOfInvention | Toluene/methanol side chain alkylation method |
| abstract | The invention relates to a toluene/methanol side chain alkylation method and mainly aims at solving the problems of low styrene selectivity and poor stability of catalysts in the prior art. The problems are well solved by virtue of the following technical scheme: toluene and methanol are taken as raw materials; the raw materials are in contact with a catalyst and react to generate ethylbenzene and styrene under the conditions of a reaction temperature of 200-600 DEG C, a reaction pressure of 0-0.5 MPa and a raw material weight space velocity of 0.5-10 h＜-1＞; the molar ratio of the toluene to the methanol in the raw materials is 0.1-10; the catalyst is prepared from the following components in percentage by weight: a) 93-99.8% of alkali metal ion exchange molecular sieve, b) 0.1-0.5% of rare earth element, and c) 0.1-2% of at least one of boron or phosphorus; and the toluene/methanol side chain alkylation method is applicable to the industrial production of preparing the ethylbenzene and the styrene by virtue of toluene/methanol side chain alkylation. |
