Preparation of Insensitive RDX From Crude RDX Using an Antisolvent Phase Separation Process

摘要

This paper describes the separation of two of the most widely used explosive compounds, RDX (1,3,5-Trinitro-1,3, 5-triazacyclohexane) and HMX (1,3, 5,7-tetranitro-1,3,5,7- tetraazacyclooctane). A simple antisolvent phase separation process to obtain more than 99 % pure RDX from an explosive mixture consisting of RDX (approx. 90 %) and HMX (approx. 10 %) was developed. The process does not require modifications to the existing RDX manufacturing process, and only minimal amounts of new waste products and solvents are generated as there is no chemical reaction or complexation involved in this new process.
