TNCrs

Trinitrocresolo (TNCrs). Its isomer, Trinitro-metacresolo (Trinitro-m-methylphenol) is described in Belgrano (Ref 31, pp 291—92). Was used in Italy in mixture TNCrs 60 PA 40%, under the name Cfesilite (qv), for military purposes... 

DNB — Dinitrobenzene DNCB — Dinitrochlorobenzene DNCr — Dinitiocresole DNPh — Dinitro-phenol DNT — 2,4, Dinitrotoluene EtN — Erythritol Tetranitrate HNDPhA — Hexanitio-diphenylamine MHeN — Mannitol Hexanitrace MNPh — Mononitrophenol MNT — Mononitrotoluene PA — Picric Acid PETN — Pentaerythritol Tetranitrate TNAn — Trinitroaniline TNAns — Tri-nitroanisole TNB — Trinitrobenzene TNCr — Trinitrocresole TNPh — Tri nitro phenol TNT —... 

One methyl group reduces the strength of TNB less than do two methyls in TNX, and the weakest is TNMes with three methyls. TNT is a stronger expl than TNCrs, which differs... 

Properties of Chlorate Explosives. In general, expls based on chlorates are very powerful and brisant, but are very sensitive to friction and impact. Coating of particles of chlorates with substances such as castor oil, rosin, paraffin, tar, aromatic nitrocompds, crude rubber, vaselin, pertoleum, plastic materials, diminish considerably the sensitiveness but not sufficiently to make these expls suitable for loading artillery shells(See CHEDDITES) The chlorate expls are more sensitive than those contg perchlorates, and expls contg Na chlorate are more sensitive than those with K chlorate. Expls contg K or Na chlorate should not be mixed with Amm salts because, in this case, double decomp takes place with the formation of Amm chlorate which can explode spontaneously. It also is advisable not to use either PA or.TNCrs in chlorate expls, because such mixts are very sensitive(Ref 7,p 383). These precautions were not always followed... 

The mixt of TNCrs 60% PA 40% is called Cresylite No 2 (Ref 13). It becomes plastic at 65-70° and melts at 85°. On being remelted the mixt at first assumes a pasty consistency, after which (6 hrs) it solidifies to an extremely compact substance. It has been used as a HE bursting chge, cast loaded into some projectiles. The same mixt was adopted in Italy under the name Cresilite. It is called by Molina (Ref 12) Ecrasite...
