The invention addresses a problem of purifying a monomer to be a precursor according to a simpler and milder method so as to obtain a polymer having a higher molecular weight. The invention relates to a method for producing a condensed polycyclic aromatic compound having n active groups (wherein n is an integer of 1 or more and 4 or less), which comprises bringing a composition containing the condensed polycyclic aromatic compound and a solvent into contact with zeolite.
本发明所要解决的问题是,根据一种更简单、更温和的方法将单体提纯为前体,从而获得分子量更高的聚合物。本发明涉及一种生产具有 n 个活性基团(其中 n 为 1 或以上 4 或以下的整数)的缩合多环芳香族化合物的方法,该方法包括将含有缩合多环芳香族化合物和溶剂的组合物与沸石接触。
