High-density HNIW/TNT cocrystal synthesized using a green chemical method

Abstract

HNIW/TNT cocrystals are synthesized by a new chemical method. The performance of the cocrystals is improved from previous preparation techniques and this new method is a more environmentally friendly approach.

Optimized energetic HNTO/AN co-crystal and its thermal decomposition kinetics in the presence of energetic coordination nanomaterials based on functionalized graphene oxide and cobalt

“…Thus, a co-crystal is a new crystal constituted by two or more chemical elements with a proper stoichiometric ratio linked with hydrogen bonding, van der Waals forces, p-p stacking and p-p stacking, and/or other non-covalent interactions. [17][18][19] Several energetic co-crystals with interesting features have been developed so far and the topic continues to attract current/future and increasingly intense international discussion to fulll the requirement of the next generation of EMs. [20][21][22] As one of the most interesting propellant oxidizer and explosive ingredient, AN displays prominent characteristics such a positive oxygen balance, low cost, availability, and 100% of gaseous decomposition products.…”

Recent Progress on Synthesis, Characterization, and Performance of Energetic Cocrystals: A Review

“…Solvent-assisted grinding is an environmentally friendly method; however, it is difficult to control the cocrystals’ morphologies [ 43 ]. L. Yan et al reported an energetic cocrystal (HNIW/TNT) synthesis using a solvent-assisted grinding method [ 47 ]. In their work, they used ethanol as a solvent due to its environmentally friendly nature.…”

Solid Propellant Formulations: A Review of Recent Progress and Utilized Components

“…Recently, many studies [49][50][51] on development of co-crystals, such as a co-crystal composed of hydrazine 3-nitro-1,2,4-triazol-5-one (HNTO) and ammonium nitrate (AN). This co-crystal was developed in order to overcome some of the drawbacks (i.e., high hygroscopicity and phase transitions of AN and negative oxygen balance of HNTO) of AN and HNTO [49].…”
