Method for toluene alkylation with methanol

The invention relates to a method for toluene alkylation with methanol and the method is mainly used for solving the problem of the prior art that the reactivity is obviously reduced while the selectivity is improved during the toluene alkylation with methanol. The method is characterized in that toluene and methanol are adopted as raw materials and contacted with a catalyst to produce xylene and water, wherein the catalyst adopted comprises the following components in parts by weight: a) 5 to 95 parts of silicon modified core-shell molecular sieve, and 5 to 95 parts of adhesive, wherein the nuclear phase of the silicon modified core-shell molecular sieve is an ZSM molecular sieve, the core shell is an Silicalite-1 molecular sieve, and a silicon dioxide layer covers outside the core shell; the weight ratio of core to shell is (0.01-3):1; the silicon dioxide layer accounts for 1-30wt% of the core-shell molecular sieve. According to the technical scheme, the problem in the prior art can be better solved and the method is applicable to the industrial production of toluene alkylation with methanol.
