Abstract: A process for the preparation of alkane- and arenesulfonamides in high purity and yield is provided. Ammonia or alkylamine is reacted under boiling conditions with an alkane- or arenesulfonyl halide in the absence of an added solvent. The heat of reaction is dissipated by the heat of vaporization of the ammonia or alkylamine.
Abstract translation: 提供了一种以高纯度和高产量制备烷烃和芳烃磺酰胺的方法。 在不存在加入的溶剂的情况下，氨或烷基胺在沸腾条件下与烷烃或芳烃磺酰卤反应。 反应的热量由氨或烷基胺的蒸发热消散。
