The invention provides an efficient process for producing alkylated aromatic compounds such as cumene in a compact reactor. The invention also provides a process for producing phenol which includes a step of producing cumene by the above process. The process for producing alkylated aromatic compounds of the invention includes feeding raw materials including an aromatic compound and an alcohol in a gas-liquid downward concurrent flow mode to a fixed-bed reactor packed with a solid acid catalyst thereby to produce an alkylated aromatic compound, wherein the raw materials are fed to the reactor in a stream of a gas, and the reaction gas flow rate defined by the equation below is not less than 0.05 at an entrance of a solid acid catalyst layer:&#x3c1;g&#xb7;ug&#xb7;[&#x3c1;air&#xb7;&#x3c1;water/(&#x3c1;g&#xb7;&#x3c1;l)](kgms).

Process for producing alkylated aromatic compounds and process for producing phenol

The invention provides processes for producing 2-propanol with higher purity than heretofore possible while suppressing the by-production of impurities. A process of the invention produces 2-propanol by reacting acetone with hydrogen in the presence of a hydrogenation catalyst, wherein the process includes reacting a raw material mixture containing water and acetone, with hydrogen in the presence of a hydrogenation catalyst, and the raw material mixture contains water at 1.2 to 4.0 wt % based on 100 wt % of the total of the water and the acetone.

Process for producing 2-propanol

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:&#x3c1;g&#xb7;ug&#xb7;[&#x3c1;air&#xb7;&#x3c1;water/(&#x3c1;g&#xb7;&#x3c1;l)](kgms).
