286 NITRIC ESTERS are less sensitive to mechanical shock than PETN, and three out of four of them have conveniently low melting points which permit them to be loaded by pouring Tetramethylolcyclopentanone tetranitrate, called nitropentanone for short, melts at 74°. Tetramethylolcyclopentanol pentamtrate is called nitropentanol and melts at 92°. Tetramethylolcyclohexanone tetranitrate, m.p. 66°, is called nitrohexanone, and tetramethylolcyclohexanol pentamtrate, m p. 122 5°, nitrohexanol. They are less brisant than PETN. Wohler and Roth 122 have measured their velocities of detonation at various densities of loading, as follows.

CHAPTER VI SMOKELESS POWDER An account of smokeless powder is, in its main outlines, an account of the various means which have been used to regulate the temperature and the rate of the burning of nitrocellulose. After the degree of nitration of the nitrocellulose, other factors which influence the character of the powder are the state of aggregation of the nitrocellulose, whether colloided or in shreds, the size and shape of the powder grains, and the nature of the materials other than nitrocellulose which enter into its composition. Bulk Powder The first successful smokeless powder appears to have been made by Captain Schultze of the Prussian Artillery in 1864. At first he seems only to have impregnated little grains of wood with potassium nitrate, but afterwards he purified the wood by washing, boiling, and bleaching, then nitrated it, purified the nitrated product by a method similar to that which had been used by von Lenk, and finally impregnated the grains with potassium nitrate alone or with a mixture of that salt and barium nitrate. 1 The physical structure of the wood and the fact that it contained material which was not cellulose both tended to make the nitrated product burn more slowly than guncotton. The added nitrates further reduced the rate of burning, but Schultze's powder was still too rapid for use in rifles. It found immediate favor for use in shot guns. It was manufactured in Austria by a firm which in 1870 and 1871 took out patents covering the partial gelatinization of the powder by treatment with a mixture of ether and alcohol. The improved powder was manufactured between 1872 and 1875 under the name of Collodin, but the Austrian gov- 1 Brit. Pat. 900 (1864). 287
