METHOD OF PRODUCING 1-PHENYLETHANOL AND PARA-SUBSTITUTED 1-PHENYLETHANOL Russian patent published in 2013 - IPC C07C33/22 C07C33/46 C07C205/19 C07C29/145 C07C201/12

Abstract RU 2487860 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 1-phenylethanol or para-substituted 1-phenylethanol, which is used as intermediate compounds in various areas of organic chemistry. The method involves catalytic reduction of substituted acetophenones in a flow reactor in a supercritical two-component solvent using a heterogeneous granular catalyst - aluminium oxide Al₂O₃ at temperature of 170-230°C and pressure of 170-190 atm.

EFFECT: method enables to obtain end products with high output over a contact time of a few minutes without using expensive catalysts.
