Abstract
The chlorination of paraffins is carried out in the presence of water and in the absence of an organic solvent. In this way, it is possible to prepare highly chlorinated paraffins in a simple manner. The presence of hydrochloric acid even at high temperatures, has no deleterious effect on the quality of the product. The separation of the chloroparaffin from the hydrochloric acid is very good. An emulsion layer which hinders the transport of the chloroparaffin into downstream equipment does not occur.
