Abstract
Official abstract text for this publication.
Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The present processes make use of sulfuryl chloride, or chlorine gas, as a chlorinating agent.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the production of chlorinated propanes comprising catalyzing the addition of at least two chlorine atoms to a propane with a catalyst system comprising at least one Lewis acid and one or more nonmetallic iodides and/or from 1 ppm to 5000 ppm elemental iodine. 2. The process of claim 1 , wherein the source of chlorine atoms comprises chlorine gas, sulfuryl chloride or a combination of these. 3. The p…
