    • A process for washing hydrocarbons said process comprising: (I) distilling a crude acetone mixture preferably obtained from the cleavage of cumene hydroperoxide and containing hydrocarbons and water so as to form a bottoms fraction containing said hydrocarbons in an organic phase and an aqueous phase; (II) contacting at least a part of said bottoms fraction with an aqueous metal hydroxide solution so as to provide a concentration of 0.1 to 5 wt% MOH, where M is an alkali metal, in the aqueous phase; (III) separating the aqueous phase and the organic phase; (IV) contacting at least a part the organic phase from step (III) with an aqueous metal hydroxide solution so as to provide a concentration of 6 to 20 wt% MOH in the aqueous phase; (V) separating the organic phase and aqueous phase formed in step (IV); (VI) washing at least a part of the organic phase of step (V) with water.
    • 一种用于洗涤烃的方法,所述方法包括:(I)蒸馏粗制丙酮混合物,优选由氢过氧化枯烯的裂解获得并含有烃和水,以便形成含有有机相和水相中的烃的塔底馏分; (II)使所述塔底馏分的至少一部分与金属氢氧化物水溶液接触,以在水相中提供其中M为碱金属的0.1至5重量%的MOH浓度; (III)分离水相和有机相; (IV)使来自步骤(III)的有机相的至少一部分与金属氢氧化物水溶液接触,从而在水相中提供6〜20重量%的MOH浓度; (V)分离步骤(IV)中形成的有机相和水相; (VI)用水洗涤步骤(V)的至少一部分有机相。
