Abstract
<PICT:0566783/IV/1> Dichlorobutenes are prepared by chlorinating butadiene by a process which comprises dissolving butadiene in one portion of an inert solvent, dissolving chlorine in another portion of the same solvent and mixing the two solutions. The process is preferably carried out as a continuous process. Suitable inert solvents mentioned include chloroform, carbon tetrachloride and carbon bisulphide. Hydrocarbon solvents, such as butane and hexane, may also be used, but are not preferred, since they are not entirely inert. The process is preferably carried out at a temperature below 70 DEG C. to avoid polymerization. In an example, solvent from a container 12 flows into the reaction vessel 1, and chlorine and butadiene are supplied through inlets 3 and 4 respectively. The solutions mix in the reaction vessel and the solution of the reaction product is withdrawn through pipes 5 and 6 to condenser 8. This is kept at such a temperature that the reaction product is condensed into the receiver 9 while the solvent passes over through pipe 10 to condenser 11, where it is condensed and returned for reuse to storage vessel 12.
