Abstract RU 2405765 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing benzyl alcohol, used in primary organic synthesis, textile, paint-and-varnish and medical industry. The method involves alkaline hydrolysis of benzyl chloride, which is obtained by treating dibenzyl ether with hydrochloric acid in two steps, at the first step at temperature 85-90°C with 30-40% hydrochloric acid with weight ratio of dibenzyl ether to hydrochloric acid equal to 1:3-4, at the second step at temperature 100-108°C with 30-40% hydrochloric acid with weight ratio of dibenzyl ether to hydrochloric acid equal to 1:2-3, with recycling of the obtained crude benzyl chloride to the hydrolysis step.

EFFECT: improved and simple method of producing benzyl alcohol by recycling wastes of said production, which improves cost-performance ratio of the disclosed method.
