    • 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.
    • 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。 该方法包括以下步骤:(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是C3至C8烷基部分,第二烷基取代基是C 4 + n至C 8 + n直链烷基部分,其中n为0至42,并且其中第二烷基取代基为至少一个碳原子较大 比第一烷基取代基; (b)在含氧源的存在下使含有主要量的对二(烷基取代)芳族化合物的异构体混合物经受氧化条件,由此转化为C3至C8烷基部分的第一烷基取代基 涉及含氢过氧化物的取代部分以产生包含主要量的对位线性烷基取代的含氢过氧化物的取代的芳族化合物的异构体混合物; 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。
