FIELD: chemistry.
SUBSTANCE: invention concerns method of isopropylbenzene hydroperoxide (IPBHP) concentration, applied in phenol and acetone production by isopropylbenzene method. The claimed method involves feed of oxidate for rectification into a vessel with gas phase separation in top part or into condensers of rectification columns.
EFFECT: reduced load on columns, enhanced column efficiency, reduced loss of IPBHP with distillate, power saving.
