Characterization and Performance Evaluation of Recrystallised Micro PETN

Abstract

This manuscript shows the recrystallization of micro Pentaerythritol tetranitrate (mcPETN) through solvent anti solvent technique by changing some important parameters viz., rotations per minute, temperature of crystallization, while keeping the concentration of PETN constant as in solvent acetone. The synthesized mcPETN is characterized for its crystal structure and morphology. The enhanced performance to its macro sized PETN is reported herewith the results.

Synthesis and Characterization of Pentaeritritol Tetranitrate (PETN)

“…It has a high detonation temperature, due to the large amount of oxygen, low vapor pressure and, consequently, low dispersion in the environment [4]. Thermal stability of PETN may be affected by factors such as particle size and crystal lattice instabilities [5], suggesting the reduction of crystal size to micro scale, which allow corrections of instability problems. The has polymorphic variations: PETN-I, or α-PETN, tetragonal structure and PETN-II, also known as β-PETN, with orthorhombic formation.…”
