Glycerol chlor hydrines

SAChloroptopane 1,2 dl ol I,2 di nf trate a Dinitrochlorohydrin or Glycerol Monochloro-hydrin Dinitrate (called Disalpetersaureester des y-Chlor proplyeneglykols, 3-Chlor -propyl englykol-dinitrat or Dinicromonochlor-hydrin in Get), CI.CH2.CH(ON02).CH2(ON02)2 ... 

The tri-chlor hydrine is plainly tri-chlor propane, a simple tri-halogen substitution product of propane. It has already been mentioned in connection with the synthesis of glycerol from propane. Of the esters which glycerol yields with the inorganic acids those formed with nitric acid are the most important.

Epi-chlor Hydrines.—An important reaction takes place with mono-chlor hydrines which contain at least two remaining hydroxyl groups, as, e.g.j those derived from glycerol. The mono-chlor hydrines lose water and are converted into anhydrides known as epi-chlor hydrines. The reactions take place most readily with the alpha-chlor... 

The glycerol is converted into the symmetrical, or, i -3 -di-chlor-hydrine. By oxidation this yields the symmetrical, or, 1-3-di-chlor acetone, which by the addition of hydrogen cyanide yields the addition product, that on hydrolysis is converted into a hydroxy acid, viz., di-chlor hydroxy iso-butyric acid. By treatment with potassium cyanide this yields the corresponding di-cyanide, or nitrile of citric acid which on hydrolysis yields citric acid.
