Nitroglycerine specific gravity

Butylene-1,3-glycol dinitrate (1,3-butanediol dinitrate), also called dinitro-butylene glycol , is an oily liquid (at 15°Q which does not freeze at a temperature of —20°C. Its specific gravity is 1.32. Dinitrobutylene glycol is more volatile than nitroglycerine, but less so than nitroglycol. Collodion cotton dissolves in it fairly easily [4,37]. 

The dinitroglycerin obtained by the nitration of glycerin is a colorless, odorless oil, more viscous and more volatile than nitroglycerin. It causes the same kind of a headache. It has a specific gravity of 1.51 at 15°, boils at 146-148° at 15 mm. with only slight decomposition, and solidifies at —40° to a glassy solid which melts if the temperature is raised to —30°. It is readily... 

Mononitroglycerin is a by-product in the preparation of dinitroglycerin and is separated from the latter substance by its greater solubility in water. It is usually obtained as a colorless oil, density 1.417 at 15°, more viscous than dinitroglycerin and less viscous than nitroglycerin. This oil is a mixture of the two isomers which are crystalline when separate but show little tendency to crystallize when they are mixed. a-Mononitroglycerin when pure consists of colorless prisms, m.p. 58-59°, specific gravity 1.53 at 15° it yields both of the dinitrates on nitration. The -compound crystallizes in dendrites and leaflets, m.p. 54°, and is more readily soluble in ether than the a-compound it yields only the a,/ -dinitrate on nitration. Both isomers boil at 155-160° at 15 mm. 

Nitroglycol is a colorless liquid, only slightly more viscous than water, specific gravity (x /15 ) 1.5176 at 0 , 1.5033 at 10 , and 1.4890 at 20 . It freezes at about —22.3 . Rinkenbach reports the index of refraction of nitroglycol for white light to be 1.4452 at 22.3 , and that of a commercial sample of nitroglycerin under the same conditions to be 1.4713. The same author reports the vapor pressure of nitroglycol to be 0.(X)7 mm. of mercury at 0 and 0.0565 mm. at 22 , and points out that its vapor pressure... 

A study of the preparation and properties of dinitrodiglycol was reported by Rinkenbach in 1927 and a further study of the nitration of diethylene glycol by Rinkenbach and Aaronson in 1931. Dinitrodiglycol is a viscous, colorless, and odorless liquid, specific gravity (x°/15°) 1.4092 at 0 , 1.3969 at 10°, and 1,3846 at 20 , freezing point —11.5 . It is completely miscible at ordinary temperatures with nitroglycerin, nitroglycol, ether, acetone,... 

The quantity of the high explosive of the true AC type tested depends naturally on its specific gravity, with the result that it ranged from 0.4 g for nitrocellulose, which is composed of gun cotton and collodion cotton, to 2.4 g for nitroglycerin in the case of high explosives of the true AC type tested herein. 

Nitroglycerin thus obtained was oily, heavy, transparent and colorless liquid. Its specific gravity was found to be 1.598 at 15 °C. 

If the nitroglycerine it suspected to contain compounds such as dinitrochlorhydrin, it may be examined by specific gravity, nit en content, chlorine content, refractive index, Nitrosugan increase the viscosity and lower the nitrogen content. Hoffman and Hawse give a polarimetric method for nitrosugars.
