A Thermal and Nanomechanical Study of Molecular Crystals as Versatile Mocks for Pentaerythritol Tetranitrate

Crystals, 2020
Pentaerythritol tetranitrate (PETN) is a commonly used high explosive (HE) in detonators. Often, surrogate or “mock” materials are used in place of HE for mechanical tests, proofing out equipment, or developing new diagnostics. However, there

PETN homologs

, 1972
High purity nitrate esters of the pentaerythritols can be successfully synthesized from correspondingly high purity reagents. The latter are not commercially available, but may be purified through molecular distillation and/or fractional crystallization from xylene. The isolated products are ultimately saponified to reagents of high purity.
