Abstract

The present invention relates to a cresol producing method through phenol methanol gas phase alkylation. The phenol and methanol are preheated and then are mixed with diluent gas; then the mixed gas continuously passes through a phenol methanol alkylation catalyst bed layer; and finally gas phase reaction is performed under the reaction condition that the reaction temperature is 200? 500? and the feeding airspeed is 0.5 20h to produce cresol. The phenol methanol alkylation catalyst is prepared through modification by taking MCM 22 ZSM 5 and the beta molecular sieve as the active components. The phenol and methanol are used as the raw materials the selectivity of the cresol can reach 90% the para selectivity can reach 58% and the catalyst has good stability. No corrosion occurs in the device during the production process. The catalyst is an environmentally friendly catalyst and has a desirable industrial application prospect.
