    摘要: A process for preparing an alkylene oxide, which process comprises: (i) oxidizing an alkylebenzene to obtain a stream comprising alkylbenzene hydroperoxide; (ii) contacting at least part of the alkylbenzene hydroperoxide obtained in step (i) with an olefin to obtain a product stream comprising an alkylene oxide; (iii) separating alkylene oxide compound from the product stream of step (ii) to obtain (a) a residual product stream comprising alkylphenyl alcohol, and (b) alkylene oxide; (iv) feeding at least a part of the residual product stream comprising alkylphenyl alcohol to a reactor having a catalytic distillation zone, and concurrently in the reactor: (a) contacting the residual product stream comprising alkylphenyl alcohol with hydrogen in the catalytic distillation zone to convert the alkylphenyl alcohol in the residual product stream to alkylbenzene and from a reaction mixture; and, (b) separating alkylbenze from the reaction mixture by fraction distillation; (v) withdrawing a stream comprising alkybenzene and having a reduced concentration of alkylphenyl alcohol than the feed stream from the reactor at a position upper from the catalytic reaction zone; withdrawing from the reactor at a position lower than the catalytic distillation zone a bottom stream comprising dimer(s) of alkylbenzene; alkylbenze; and. (viii) recycling at least a part of the alkylbenzene produced from (iv)(b) and/or (vi) to step (i).

    摘要: The invention relates to a method for the epoxidation of an organic compound comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent. Said method is characterised in that a product mixture containing α-hydroperoxy alcohols is reduced using at least one reductant. The invention also relates to a method for the epoxidation of an organic compound comprising at least one C-C double bond, using hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent, characterised in that said method comprises at least the following steps: (i) an organic compound comprising at least one C-C double bond is reacted with hydrogen peroxide in the presence of at least one catalytically active compound and at least one solvent to obtain a product mixture P1 containing α-hydroperoxy alcohols; (ii) an epoxide that has been obtained by the reaction in step (i) is separated from P1 or P1', together with the non-converted organic compound comprising at least one C-C double bond, to obtain a product mixture P2 or P2', P2 containing the α-hydroperoxy alcohols that have occurred as by-products in the reaction in step (i) and P2' being substantially devoid of α-hydroperoxy alcohols. (iii) at least one reductant is added to P1 and/or P2, whereby the α-hydroperoxy alcohols are converted into corresponding glycols, obtained in a product mixture P1' or P3.
