Pentaerythritol trinitrate (Petrin) is a little-known yet powerful explosive with a detonation speed of up to 8450 m · s ⁻¹ . Like the more common pentaerythritol granitrate known as nitropenta , trinitrate also has a strong vasodilatory effect .

Manufacture and composition

Pentaerythritol trinitrate is a nitrate (an ester of nitric acid) of pentaerythritol. It occurs either as a by-product in the classic esterification of pentaerythritol with nitric acid or is obtained by nitration of pentaerythritol with a mixed acid. A small part of the tetranitrate is produced there.

properties

The detonation speed is at a maximum density of 1.54 g / cm³ up to 8450 m · s ⁻¹ . In addition, pentaerythritol trinitrate has a molar mass of 271.14 g / mol and an oxygen balance of −26.6%.

The biggest disadvantage is the shorter storage time of 5 to 10 years compared to Nitropenta.

Legal position

The handling, traffic, transport and import of Petrin are subject to the Explosives Act .
