Pentryl—

Pentryl and Pentro. Trade names for Swiss military ex pis contg mixts of PETN and TNT in various proportions. They are prepd by dissolving PETN and TNT in acetone and precipitating them with water. They are manufd by the Schwazerische Sprengstoff-Fabrik AG, Dottikon, Switzerland... [Pg.614]

Note 70/30 Pentryl contains 70% PETN and 30% TNT. See also under Swiss Commercial Explosives of Nonpermissible Type in Vol 3, C443-R... [Pg.614]

Numerous aromatic nitramines have been synthesized but only A,2,4,6-tetranitro-A-methylaniline (tetryl) and l-(2-nitroxyethylnitramino)-2,4,6-trinitrobenzene (pentryl) have found practical use as explosives. Both tetryl and pentryl are more powerful than TNT. Tetryl is widely used in boosters and as a component of explosive formulations like tetrytol (tetryl/TNT), PTX-1 (tetryl/RDX/TNT) and Composition C-3 (tetryl/RDX/TNT/DNT/MNT/NC). [Pg.240]

Pentryl (152) is obtained from the action of fuming nitric acid or mixed acid on Ai-(2,4-dinitrophenyl)ethanolamine, itself obtained from the reaction of 2,4-dinitrochlorobenzene with ethanolamine. Another route to pentryl (152) involves the nitration of A-phenylethanol-amine, which is obtained from the reaction of aniline with ethylene oxide. ... [Pg.242]

R.C. Moran prepd 2-(2, 4, 6-Trinitro-N-nitranilino)-Ethanol Nitrate, also known as Pentryl. Not to be confused with Pentryl of A. Stettbacher, which designates mixts of PETN TNT known in the US as Pentolites (See Vol 1 of Encycl, pp A425—29 and Ref 31a, p 229)... [Pg.154]

Pentryl has been prepared by two methods (a) from aniline and ethylene oxide (according to Herz [80]) and (b) from chlorodinitrobenzene and ethanolamine (according to Moran) with the subsequent nitration of N-hydroxyethylaniline or its dinitro derivative ... [Pg.70]

In contact with a metal surface heated to 235°C, pentryl explodes in 3 sec. The chemical stability of pentryl is considered satisfactory. [Pg.71]

Pentryl is less sensitive to impact than tetryl (according to Clark, the maximum height causing no explosion in the drop test is 50 cm for pentryl, whereas for tetryl it is 27.5 cm and for picric acid 42.5 cm). [Pg.71]

Medard [71] reports that pentryl, at a density of 1.56, detonates at the rate of 7180 m/sec and its lead block expansion is 114 (taking the value for picric acid as 100). Under a pressure of 1500 kg/cm2, a density of 1.68 is obtained. [Pg.71]

The minimum initiating charges for pentryl as compared with other explosives (according to Clark [78]) are listed in Table 14. [Pg.71]

The explosive properties of hexanitrodiphenyl-/ -hydroxynitraminoethyl nitrate are similar to those of pentryl. It is slightly more stable on heating its ignition temperature lies between 390 and 400°C. It is somewhat less sensitive to impact than pentryl and rather more powerful (by 3%) in the lead block test. It requires a stronger initiator than pentryl, tetryl or picric acid, but a weaker one than trinitrotoluene. [Pg.72]

Waldkotter(Ref 7) prepd pentryl from the same ingredients as Clark and reported a mp of 129°. Desseigne(Ref 10) gives detailed description for the prepn of pentryl starting with the condensation of dinitrochloroben-zene and monoethanolamine, followed by nitration of the resulting product with mixed nitric-sulfuric acid. Pentryl was also prepd and investigated in Russia(Ref 5)... [Pg.425]

The explosive props of pentryl were detnd by Clark(Ref 4) at the USBurMines and by L.Medard(Ref 9) for the "Commission des Substances Explosives. Some of these props are also listed by Desseigne(Ref 10). [Pg.425]

A few props were detnd by van Romburgh (Ref 6). A brief description of pentryl is given by Davis (Ref 8)... [Pg.425]

Following are the properties of pentryl taken from various sources ... [Pg.425]

The same thing happens when pentryl is compressed at high pressure and confined in a detonator cap and then ignited by the spit of a fuse(Ref 4,p 1386)... [Pg.426]

Brisance by Lead Plate Cutting Test. When using the proc described in ChemMetEngrg 26,1126—32(1922) and exploding a sample compressed at2320psi(l63 l kg/cmJ), pentryl cuts a hole in the plate equal in size to that made by tetryl and slightly larger than PA or TNTfRef 4,pp 1387-8) (See also Ref 8a)...

The above values indicate that the sensitivity of pentryl to detonation is similar to that of tetryl and greater than that of TNT and PA(Ref 4, p 1387)... [Pg.428]
