    • Disclosed herein is a process for preparing an isomeric mixture comprising a major amount of a para-linear mono-alkyl-substituted hydroxyaromatic compound. The process involves the steps of: (a) providing an isomeric mixture comprising a major amount of a para-di(alkyl-substituted)aromatic compound; wherein a first alkyl substituent is a C3 to C8 alkyl moiety and a second alkyl substituent is a C4+n to C8+n linear alkyl moiety, wherein n is 0 to 42 and further wherein the second alkyl substituent is at least one carbon atom greater than the first alkyl substituent; (b) subjecting the isomeric mixture comprising a major amount of a para-di(alkyl-substituted)aromatic compound to oxidation conditions in the presence of an oxygen-containing source, thereby converting the first alkyl substituent which is a C3 to C8 alkyl moiety to a hydroperoxide-containing substituted moiety to produce an isomeric mixture comprising a major amount of a para-linear alkyl-substituted, hydroperoxide-containing substituted aromatic compound; and (c) converting the hydroperoxide-containing substituted moiety to a hydroxyl moiety thereby providing an isomeric mixture comprising a major amount of a para-linear mono-alkyl-substituted hydroxyaromatic compound.

    • In a process for producing phenol and cyclohexanone, reaction components comprising cyclohexylbenzene hydroperoxide and an acid catalyst are supplied to a cleavage reaction zone, mixed under mixing conditions effective to combine the reaction components into a reaction mixture and at least part of the cyclohexylbenzene hydroperoxide in the reaction mixture is converted under cleavage conditions to into phenol and cyclohexanone; and a cleavage effluent is recovered from the cleavage reaction zone. The cleavage and mixing conditions are controlled such that the ratio tR/tM is at least 10, where tR is the half-life of cyclohexylbenzene hydroperoxide under the cleavage conditions and tM is the time required after injection of a tracer material into the reaction mixture under the mixing conditions for at least 95% by volume of the entire reaction mixture to attain at least 95% of the volume-averaged tracer material concentration.
    • 在生产酚和环己酮的方法中,将包含环己基苯氢过氧化物和酸催化剂的反应组分供应至裂解反应区,在有效将反应组分混合成反应混合物和至少部分环己基苯氢过氧化物的混合条件下混合, 在裂解条件下将反应混合物转化成苯酚和环己酮; 并从裂解反应区回收裂解流出物。 控制裂解和混合条件使得tR / tM的比例至少为10,其中t R是在切割条件下环己基苯氢过氧化物的半衰期,tM是将示踪材料注入反应混合物中所需的时间 整个反应混合物的至少95体积%的混合条件达到体积平均示踪剂材料浓度的至少95%。
