Cresol producing method through phenol methanol gas-phase alkylation

摘要

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
