A process for producing an aryl carbamate of a high purity at a high yield by reacting a diaryl carbonate with an amine compound having one or more hydrogen atoms bonded to the N position in the presence of carboxylic acid(s) of the following general formulae (I): R.sup.1 --COOH and/or (II): R.sup.2 --COOH (wherein R.sup.1 represents an alkyl or cycloalkyl group having an .alpha.-positioned carbon atom bonded to only one hydrogen atom, an alkyl group having an .alpha.-positioned carbon atom bonded to no hydrogen atom, or an aryl or heterocyclic group, and R.sup.2 represents an alkyl group having an .alpha.-positioned carbon atom bonded to two or more hydrogen atoms).
通过在以下一般式(I): R.sup.1 --COOH 和/或 (II): R.sup.2 --COOH 的
羧酸存在下,通过将二芳基
碳酸酯与具有一个或多个氢原子与N位置结合的胺化合物反应,以高纯度高产率生产芳基
碳酸酯的方法。其中,R.sup.1代表一个仅与一个氢原子结合的α位碳原子的烷基或环烷基基团,一个α位碳原子与没有氢原子结合的烷基基团,或一个芳基或杂环基团;R.sup.2代表一个与两个或更多氢原子结合的α位碳原子的烷基基团。
