, (2008/06/13)
A process for the manufacture of haloalkyl lactams having the formula STR1 wherein n is an integer having a value of from 1 to 3; m is an integer having a value of 1 or 2 and X is chlorine or bromine in the absence of an inert solvent by reacting a hydroxyalkyl lactam of the formula STR2 with a thionyl chloride or bromide in the liquid phase under anhydrous conditions, vaporizing and removing any excess thionyl halide along with SO2 by-product from the liquid reaction mixture under vacuum followed by vacuum distillation of the remaining liquid product mixture at a temperature below its decomposition and recovering said product. The product of this process can be obtained in greater than 90% yield and 99% purity.
