摘要:
Disclosed is a process for the preparation and recovery of cyclopropylacetonitrile by a novel combination of process steps beginning with a mixture of cyclopropylmethyl halide, a cyclobutyl halide and a 4-halo-1-butene. The process permits the recovery of substantially pure cyclopropylacetonitrile and cyclobutyl halide, e.g., cyclopropylacetonitrile and cyclobutyl halide each having a purity greater than 95 %.
