Chlorohydrin dinitrates

C1H2C.CH(0.N02).CH2C1 mw 173.99, N 8,0555 col very mobile liq, having an aromatic odor, fr p below -20°, bp 180-90° (dec), d 1.459 at 15° was prepd by nitrating 1,3-dichloro-hydrin with mixed acids (Ref 1). Naoum (Ref 2) reports some addnl props and compares this compd with NG Chlorohydrin Dinitrate (qy) Refs 1) Beil 1, 364 8tU473i 2) Naoum,... 

The most important of the chlorohydrin nitrates are the chlorohydrin dinitrates ( dinitrochlorohydrins ), existing in two isomeric forms ... 

The chemical stability of dinitrochlorohydrin is higher than that of nitroglycerine. It withstands the Abel heat test at 72°C for 30 min. On heating at a temperature of 75°C, the first signs of decomposition and the development of acid fumes do not appear before 10-12 days. A small quantity of chlorohydrin dinitrate heated in a test tube undergoes decomposition with the evolution of oxides of nitrogen at temperature above 170°C. Complete decomposition takes place (without explosion at 180°C. Larger quantities of the substance decompose with a weak explosion, if heated rapidly to a temperature of about 190°C. 

The explosive strength of dinitrochlorohydrin is assumed to be about 80% that of nitroglycerine. As a component of mining explosives chlorohydrin dinitrate has the disadvantage of producing hydrogen chloride on explosion. It does not seem to be any more of practical use. 

In practice, usually a mixture of chlorohydrin with 10-20% of glycerine is nitrated, to yield 165-175 parts of chlorohydrin dinitrates with nitroglycerine. 

Inorganic acid esters nitrates (e.g. methyl nitrate, nitroglycol, nitroglycerine), silicates (e.g. ethyl silicate), phosphates (e.g. triphenyl phosphate, tricresyl phosphate), mixed esters of nitric and hydrochloric acid (e.g. chlorohydrin dinitrate).
