		Nitro compounds are polar, and those with no other chemically reactive grouping are colourless or pale yellow liquids that are only slightly soluble in water.
		A nitro compound ordinarily is made by the reaction, called nitration, between nitric acid and an organic compound.
		Nitration of aromatic compounds, such as benzene or toluene, is commonly effected by treating them with a mixture of nitric and sulfuric acids at temperatures of 100° C or lower.

		The value of E for nitro- glycerine was found to be 70.5 when calculated, according to Van't Hoff's formula, from the melting point and the latent heat of fusion of the substance.
		The nitro-glycerine as it separates from the acids is raised by introducing by the pipe _f_ waste acid from a previous charge, this displacing the nitro-glycerine upwards and causing it to flow by the outlet, _j_ and pipe _k_ to the prewash tank.
		When the separation of the nitro- glycerine is complete the waste acid is run off and denitrated as usual, a portion of it being reserved for the displacement of the nitro-glycerine in a subsequent operation.

	Conversion of Aliphatic Nitrites into Nitro-compounds
		The oily nitro-compound was easily recognised by the formation of the sodium compound on the addition of alcoholic sodium hydroxide solution.[1] The nitro-compound was also reduced to the corresponding amine, which was converted into the platinichloride.
		Neogi, (T., 1914, 105, 231) has already shown that the theory of tautomerism cannot be applied to the aliphatic nitrites and nitro-compounds, as heavy atoms of silver and mercury as well as heavy alkyl radicals cannot be supposed to oscillate between an oxygen and all nitrogen atom, the true tautomerides being nitro-compounds and nitrolic acids.
		The results of the present investigation show that the conversion of aliphatic nitrites into nitro-compounds takes place at a higher temperature, but, as the yield is very small, it alone is incapable of explaining the formation of the large quantities of nitro-compounds obtained by the interaction of silver or mercurous nitrite and alkyl iodides.
