    • 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: (a) providing an isomeric mixture comprising a major amount of a para-di (alkyl-substituted)aromatic compound; wherein a first alkyi substituent is a C3 to C8 alkyl moiety and a second alkyl substituent is a C4+n to C8+n linear alkyl moiety, and further wherein the second alkyl substituent is at least one carbon atom greater than the first alkyl substituent; (b) subjecting the above isomeric mixture to oxidation conditions in the presence of an oxygen-containing source, converting the first alkyl substituent which is a C3 to C8 alkyl moiety to a hydroperoxide-containing substituted moiety; 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.
    • 本文公开了一种制备包含主要量的对位线性单烷基取代的羟基芳族化合物的异构体混合物的方法。 该方法包括:(a)提供包含主要量的对二(烷基取代的)芳族化合物的异构体混合物; 其中第一烷基取代基为C 3至C 8烷基部分,第二烷基取代基为C 4 + n至C 8 + n直链烷基部分,其中第二烷基取代基为至少一个比第一烷基取代基大的碳原子; (b)在含氧源的存在下使上述异构体混合物经历氧化条件,将C 3至C 8烷基部分的第一烷基取代基转化为含氢过氧化物的取代部分; 和(c)将含氢过氧化物的取代的部分转化为羟基部分,从而提供包含主要量的对位线性单烷基取代的羟基芳族化合物的异构体混合物。
