Title
(EN) METHOD FOR PURIFYING ALKYL HYDROPEROXIDE BY EXTRACTION WITH WATER AND SEPARATION OF THE AQUEOUS PHASE
(ZH) 用于通过用水进行提取和将水相分离来纯化烷基氢过氧化物的方法
Abstract
(EN)
The present invention relates to a method for purifying a mixture containing at least one alkyl hydroperoxide, preferably tert-butyl hydroperoxide or tert-amyl hydroperoxide, and at least one corresponding dialkyl hydroperoxide, said method comprising at least one step of extraction with water and at least one separation step which is carried out within the aqueous phase, obtained following the extraction step, in order to recover an aqueous solution which is rich in alkyl hydroperoxide. The invention also relates to an aqueous composition which is rich in alkyl hydroperoxide and contains at least 0.1% by weight of dialkyl peroxide in relation to the total weight of the composition.

(ZH)
本发明涉及用于纯化包含至少一种烷基氢过氧化物、优选地叔丁基氢过氧化物或叔戊基氢过氧化物与至少一种相应的二烷基氢过氧化物的混合物的方法,所述方法包括至少一个用水进行提取的步骤、和为收取富含烷基氢过氧化物的水溶液而在所述提取步骤之后获得的水相内进行的至少一个分离步骤。本发明还涉及含水组合物,其富含烷基氢过氧化物并且包含相对于所述组合物的总重量的至少0.1%重量的二烷基过氧化物。
