Abstract
Production of organic sulphoxides by the action of sulphoxides of lower molecular weight on organic sulphides in which the reaction is catalysed by one or more substances capable of supplying hydrogen ions to the reaction medium. The process permits yields to be obtained which exceed 90 percent, and the sulphoxide which is obtained is practically free from sulphone.
