METHOD FOR PREPARING ALKYLARYL HYDROPEROXIDE-CONTAINING PRODUCT, METHOD FOR PREPARING ALKYLARYL HYDROPEROXIDE AND METHOD FOR PREPARING ALKENYLARYL Russian patent published in 2007 - IPC C07C407/00 C07D301/19 

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to method for synthesis of alkylaryl peroxide-containing compound. Method involves the following steps: (a) oxidation of alkylaryl compound to yield the alkylaryl hydroperoxide-containing reaction substance; (b) treatment of at least part of the reaction substance containing alkylaryl hydroperoxide synthesized at the step (a) wherein this the reaction product comprises less 0.05% of sodium (by mass); (c) separation of product synthesized at the step (b) for hydrocarbon phase containing alkylaryl hydroperoxide and an aqueous phase; (d) repeating steps (b) and (c) by one or some time being optionally. Also, synthesis of alkylaryl hydroxide involves the additional treatment step (e) of at least part of hydrocarbon phase containing alkylaryl hydroperoxide synthesized at steps (c) or (d), olefin and a catalyst to yield alkylaryl hydroxide and oxirane compounds, and (f) separation of at least part of oxirane compound from alkylaryl hydroxide. Synthesis of alkenylaryl involves the additional step (g) of dehydration of at least part of alkylaryl hydroxide synthesized at step (f). Invention provides simplifying the technological process resulting to synthesis of improved substance containing alkylaryl hydroperoxide from which alkylaryl hydroxide is prepared followed by preparing alkenylaryl.

EFFECT: improved method of synthesis.
