PURPOSE:To produce m-hydroxybenzyl alcohol in a high yield by the electrolytic reduction of m-hydroxybenzoic acid in an acidic aqueous soln. by allowing m-hydroxybenzyl alcohol to always exist in the electrolytic soln. and carrying out the reaction at a specified temp. CONSTITUTION:When m-hydroxybenzoic acid is electrolytically reduced in an acidic aqueous soln. such as 10-20wt% aqueous H2SO4 soln. to produce m-hydroxybenzyl alcohol, m-hydroxybenzyl alcohol is cumulatively added during the reaction so that it always exists in the electrolytic soln. and the reaction is carried out at 20-70 deg.C, especially 30-60 deg.C.
