Abstract
Prenyl chloride (1-chloro-3-methylbutene-2) may be synthesized in increased yields by reacting isoprene with hydrochloric acid in the presence of sodium chloride. In addition, the yield may also be advantageously increased by utilizing a modified method of operation in which the distillation heads and tails fractions which are obtained from the process are recycled to the reaction zone.
