METHOD FOR PRODUCING AN ALKYLATED AROMATIC COMPOUND AND METHOD FOR PRODUCING PHENOL

摘要

The invention provides an efficient process for producing alkylated aromatic compounds by directly reacting an aromatic compound with a ketone and hydrogen in a compact reactor. The invention further provides a process for producing phenol which includes a step of producing cumene by the above alkylation process. The process for producing alkylated aromatic compounds includes feeding raw materials including an aromatic compound, a ketone and hydrogen in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a catalyst thereby to produce an alkylated aromatic compound, wherein the catalyst includes a solid acid component and a metal component, the catalyst is loaded in the fixed-bed reactor such that the catalyst forms a catalyst layer, and the reaction gas flow rate defined by Equation (1) below is not less than 0.05 at an entrance of a layer containing the solid acid: Ág ‹ ug ‹ Áair ‹ Áwater / Ág ‹ Ál 1 / 2 �¢ kgm - 2 �¢ s - 1
