COTTON POWDER. See [TONITE], also [CP].
CP1 and CP2 are varieties of nitrocotton (Coton Poudre) made in France, principally for the manufacture of [Poudre B] and other smokeless powders. CP1 is a guncotton containing about 13 per cent. of nitrogen, and only about 10 per cent. of matter soluble in ether-alcohol. CP2 is almost completely soluble in ether-alcohol, and contains about 12 per cent. of nitrogen.
CRÉSYLITE.—A French high explosive used for filling shell and other military purposes. Crésylite 60/40 consists of picric acid and nitrated cresol in about the proportions of 40 of the former to 60 of the latter. It melts below the temperature of boiling water. The nitrated cresol consists largely of trinitro-metacresol.
Crésylite No. 2 is simply crude trinitro-meta-cresol.
