Abstract
Chlorinated paraffin-wax is separated into fractions of differing molecular weight and chlorine content by short path distillation in very high vacuum, e.g. 10<-2> to 10<-4> mm. of mercury, in apparatus having condensing and evaporating surfaces which are substantially co-extensive and separated by a distance of not more than a few inches. The mono- and di-chlor compounds can in this way be separated from one another and from the higher chlorinated compounds. If the monochlor compound is desired it is preferable to use a wax of low chlorine content, e.g. 12--15 per cent; if a dichlor compound, a wax of, e.g. 20--26 per cent chlorine content. A chlorinated paraffin-wax containing 19,6 per cent chlorine on distillation at 10<-4> mm., the cooled glass condensing surface being about 1 inch from the wax, gave a fraction distilling at 85--135 DEG C. which was largely the monochlor derivative. The next fraction up to 150 DEG C. was essentially dichlor-paraffin wax. The residue gave no distillate up to 200 DEG C. and contained 31,9 per cent chlorine. Specifications 303,078, [Class 32], and 417,659 are referred to.ALSO:Chlorinated paraffin-wax is separated into fractions of differing molecular weight and chlorine content by short path distillation in very high vacuum, e.g. 10<-2> to 10<-4> mm. of mercury, in apparatus having condensing and evaporating surfaces which are substantially co-extensive and separated by a distance of not more than a few inches.
