Provided is a facile three step process for preparing 2-phenylterephthalic acid starting with p-xylene, followed by alkylation, dehydrogenation, and oxidation of the methyl groups corresponding to the origional p-xylene. The product, 2-phenylterephthalic acid, is useful as an intermediate in the synthesis of polyesters comprised of residues of 2-phenylterephthalic acid.
提供了一个简单的三步过程,用p-二
甲苯为起点,经过烷基化,脱氢和氧化甲基基团,制备2-苯基
对苯二甲酸。2-苯基
对苯二甲酸作为中间体,在合成由2-苯基
对苯二甲酸残基组成的聚酯方面很有用。
