Pentaerythritol Tetranitrate (PETN listed as 1,3-Propanediol, 2,2-[bis-(nitroxy)methyl] -dinitrate in CA since 1972, Penta Penthrite in Fr Pentrit, Niperyth, Nitropenta (NP) in Ger TEN in Russ). C(CH20N02)4, mw 316.15,... 

Aubertein Rehling (Ref 15) have shown that treatment with water at approx 100° causes PETN to hydrolyze. At 125° and under pressure, hydrolysis proceeds quite quickly, and is considerably enhanced by the presence of 0.1% HNO3. Regardless of whether it occurs in water alone or in water acidified with nitric acid, the hydrolysis produces mainly Penta-erythritol Dinitrate. A dil NaOH soln causes PETN to hydrolyze.more rapidly than acidified water. PETN neither reduces Fehling s reagent nor enters into addition products with any aromatic nitro compd. In this respect it differs from both Erythritol Tetranitrate and Nitro-mannitol... 

Due to its symmetrical structure, pentaerythritol tetranitrate (PETN, 9.10) can yield only one metabolite at each de-esterification step. All successive steps occur in humans receiving therapeutic doses of the drug [13]. The only metabolites found in blood were, in decreasing order of importance, penta-... 

A Swiss patent application (No 62314, USP application No 439767) for the material penta erythrite tetrastearate, very similar to Pentawax 177, for use as a desensitizer of PETN was brought to the attention of PicArsn. An investi-... 

Pentaerythritol tetranitrate ( nitropentaerythrite ) also has numerous trade names which are different in various countries PETN, Penthrite, Penta (English speaking countries), Pentrit, Niperyth, Nitropenta, NP (Germany), Pentryt, NP (Poland), Ten (U.S.S.R.). PETN was first obtained by the Rheinisch-Westfalische Sprengstoff A.G. in 1894 [1], by nitrating pentaerythritol.

Pentaerythrite Tetranitrate (PETN, penta, niperyth, penthrit) Four equivalents of formaldehyde in warm aqueous solution in the presence of calcium hydroxide react with one equivalent of acetaldehyde to form pentaerythrite. Three of the four react with the three a-hydrogens of the acetaldehyde, the fourth acts as a reducing agent, converts the —CHO group to —CH2— OH, and is itself oxidized to formic acid. 

Pentaerythrit-tetranitrat, Nitropentaerythrit or Pentrit (PETN). The possibilities of using PETN in both military and civilian expls were realized by Dr A. Stettbacher as early as 1916. PETN was manufd at the Schweizerische Sprengstoff-Fabrik AG, Dottikon, by nitrating technically pure pentaerythritol (called penta and abbreviated as PE in Switzerland) with fuming nitric acid of d 1 -52g/cc (see Vol 8, P94-L R). The product was purified by crystallizing it from acet its mp was 142° and cryst d 1.77g/cc...
