Abstract
Improvements in the preparation of amides or lactams by isomerization of the respective ketoximes by sulfuric acid and hot, characterized by carrying out isomerization in the presence of a liquid that distills at the working temperature and that is practically inert to sulfuric acid, so that this inert liquid is vaporized by the heat of the reaction and thus absorbs the excess heat developed, maintaining the reaction at a temperature that is not dangerous.
