230 NITRIC ESTERS British and German patents 5B for its use for certain military purposes. The genesis of pentryl from ethylene, through the intermediacy both of ethanolamine and of phenylethanolamine, is indicated below. The preparation and properties t>f pentryl have CH2 'CH2 lCH2-Cl & ' CH2-OH
PENTRYL 231 tetryl by one of 27.5 cm., and one of picric acid by a drop of 42.5 cm., while TNT was not exploded by a drop of 100 cm. It is somewhat more sensitive to friction than tetryl, and much more sensitive than picric acid and TNT. Pentryl explodes in 3 seconds at 235°. The results of Clark's experiments to determine the minimum amounts of primary explosive necessary to initiate the explosion of pentryl and of other high explosives are tabulated below. For Pentryl .... Picric acid ... . TNT Tetryl Trimtroresorcinol Trinitrobenzaldehyde Tetranitroamline MINIMUM INITIATING CHARGE (GRAMS) OF Diazodinitrophenol 0 095 0115 0.163 0.075 0.110 0.075 0.085 Mercury Fulminate 0.150 0.225 0240 0165 0225 0.165 0.175 Lead Azide 0.025 0.12 0.16 0.03 0.075 0.05 0.05 Hexanitrodiphenylamine 0.075 0.165 0.05 the.purpose of these experiments a half-gram portion of the high explosive was weighed into a No. 8 detonator shell, a weighed amount of primary explosive was introduced on top of it, and both were compressed under a reeoforcing capsule at a pressure of 3400 pounds per square inch. Without the reenforcing capsule diazodinitrophenol did not cause detonation, and pentryl required 0.035 gram of lead azide and more than 0.4 gram of fulminate. The results show that pentryl has about the same sensitivity to initiation as tetryl and hexanitrodiphenylamine. In the small Trauzl test pentryl caused an expansion of 15.8 cc, while the same weight of tetryl caused one of 13.8 cc, TNT 12.2 cc, and picric acid 12.4 cc. In the small lead block compression test, in which 50 grams of the explosive was exploded by means of a detonator on top of a lead cylinder 64 mm. long, it was found that pentryl produced a shortening of the block of 18.5 mm., tetryl 16.6 mm., picric acid 16.4 mm., TNT 14.8 mm,, and diazodinitrophenol 10.5 mm. Determinations of velocity of detonation made with half-meter lengths, the explosives being contained in extra light lead tubing y2 inch internal diameter and weighing 12 ounces to the foot, gave the following figures.
