Abstract:
A process for preparing a C.sub.14 -C.sub.40 chlorinated paraffin having a chlorine content of more than 60% by weight from a C.sub.14 -C.sub.40 paraffin reactant having less or no chlorine, said process comprising:reacting the C.sub.14 -C.sub.40 paraffin reactant with an amount of liquid chlorine which essentially completely reacts with the paraffin to form a chlorinated paraffin phase of said C.sub.14 -C.sub.40 chlorinated paraffin having a chlorine content of more than 60% by weight, under superatmospheric pressure essentially in the absence of an organic solvent at an elevated temperature ranging up to about 140.degree. C., and in the presence of a free radical forming catalyst, said C.sub.14 -C.sub.40 paraffin being in intimate mixture with an aqueous phase, the intimate mixture being maintained by stirring, said reacting being continued until a chlorinated paraffin phase and an aqueous hydrochloric acid phase have been formed; andseparating said chlorinated paraffin phase from said aqueous phase.
