FIELD: manufacture of alcohols, more particularly preparation of methylphenyl carbinol. SUBSTANCE: present invention discloses method of preparing methylphenyl carbinol by liquid phase hydrogenation of acetophenone on fixed catalyst comprising copper, zinc and aluminium and having prolonged period of effective service life. Hydrogenation is carried out in flow reactor with fixed catalyst bed at elevated temperature and pressure. The weight ratio of copper to zinc components ranges from 2:1 to 40:1 at aluminium content of 40-60 wt %. EFFECT: more efficient preparation method. 6 tbl
