ABSTRACT:
A process is provided for the production of hydroxybenzyl alcohols, comprising condensing phenol with formaldehyde in an alkaline solution to form a mixture of ortho- and para-hydroxymethyl phenols, and solvent extracting unreacted phenol from the resulting alkaline hydroxybenzyl alcohol condensate solution. The phenol-reduced hydroxybenzyl alcohol condensate solution is particularly suited for treatment with excess caustic and subsequent oxidation of the resulting aqueous solution of ortho- and para-hydroxybenzyl alcohols-sodium salt to yield the corresponding ortho- and para-hydroxybenzaldehydes-sodium salt.
