Abstract
A continuous process for the photochemical chlorination of a liquid organic feed of aliphatic or alicyclic hydrocarbons or partially chlorinated hydrocarbon derivatives thereof, containing three to eight carbon atoms in the molecule inclusive comprises maintaining a circulating stream of liquid polychlorohydrocarbon in communication with a reaction zone containing the main body of liquid polychlorohydrocarbon, separately injecting the reactants consisting of liquid chlorine and liquid organic feed comprising an aliphatic or alicyclic hydrocarbon or partially chlorinated hydrocarbon derivative thereof containing three to eight carbon atoms in the molecule inclusive into said circulating stream of liquid polychlorohydrocarbon, maintaining the chlorine feed rate and the chlorinator temperature such that 90% of the reactants entering said reaction zone are in the liquid phase, passing the mixture so produced through an irradiated reaction zone to effect chlorination of the organic feed, withdrawing a portion of said circulating stream leaving the reaction zone and recovering said portion as product. In a modification of the process separate circulating streams of liquid polychlorohydrocarbon are used and the reactants consisting of liquid chlorine and the liquid organic feed are separately injected into the said separate circulating streams and wherein after withdrawing a portion of the said circulating streams leaving the reaction zone to a product recovery zone, the remaining portions of the circulating streams are passed through heat exchangers to maintain the temperature of the liquid polychlorohydrocarbon in the reaction zone between about 25 DEG and 150 DEG C. The latter process may be operated so that the reactants entering the reaction zone are maintained substantially in solution. Apparatuses are described with reference to Figs. 1 and 2 (not shown) for carrying out the processes with one and two circulating streams of liquid polychlorohydrocarbon respectively. Examples relate to the chlorination of pentane to produce a product of average composition C5Cl6,6H5,5 (1) and propane to produce a product of average composition C3H3,5Cl4,4
