Abstract

Alkanes substituted by chlorine atoms and/or sulfochloride groups are prepared by reacting alkanes with chlorine, with or without sulfur dioxide, in a particular throughput ratio, in a reaction chamber inclined to the horizontal, the starting materials being passed through the reaction chamber in co-current, from below. The substituted alkanes or paraffins obtainable by the process of the invention are pesticides, plasticizers, solvents and starting materials for the preparation of such products, as well as of fat liquors, detergents, lubricating oils, synthetic resins and slip agents.
