Abstract:
A process for preparing alkylaryl hydroperoxide containing product, which process comprises:(a) oxidating an alkylaryl compound to obtain a reaction product containing alkylaryl hydroperoxide; (b) contacting with water at least part of the alkylaryl hydroperoxide containing reaction product obtained in step (a) which reaction product contains less than 0.05% wt of sodium; (c) separating the product of step (b) into a hydrocarbonaceous phase containing alkylaryl hydroperoxide and an aqueous phase; (d) optionally repeating process steps (b) and (c) one or more times; (e) contacting at least part of the hydrocarbonaceous phase containing alkylaryl hydroperoxide obtained in step (c) or (d) with olefin and catalyst to obtain alkylaryl hydroxide and oxirane compound; and, (f) separating at least part of the oxirane compound from the alkylaryl hydroxide.
