    Abstract: By reacting an aromatic compound containing at least one trichloromethyl group bonded to an aromatic carbon atom with an aliphatic acid anhydride in the presence of a catalyst, an aromatic acid chloride and an alkyl carboxylic acid chloride are produced. The desirable products are preferably obtained through distillation at ambient conditions. Although various catalysts can be employed, an acid catalyst, such as sulphuric acid is preferred.

    Abstract translation: 通过在催化剂存在下使包含至少一个与芳族碳原子键合的三氯甲基的芳族化合物与脂族酸酐反应，生成芳族酰氯和烷基酰氯。 优选的产物优选通过在环境条件下蒸馏获得。 尽管可以使用各种催化剂，但优选酸催化剂，例如硫酸。
