A method of synthesising an organic high explosive includes the steps of i) providing a first solution A, ii) providing a second solution B, wherein the admixture of solution A and solution B are selected such that they are capable upon formation of the admixture of reacting together to provide an organic high explosive, and iii) causing the solution A and B to be mixed and passed through a flow reactor to create an admixture, wherein the flow reactor includes a pipe, wherein the internal diameter of the pipe is selected such that it is less than the critical diameter of the organic high explosive, thereby preventing detonation of the formed organic high explosive in said flow reactor.

Formation of methanoic acid, during the production of Hexahydro-1,3,5-trinitro-1,3,5-triazine and Octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine via the legacy Bachmann nitrolysis process, is avoided when the workup is performed under neutralized, anhydrous conditions. The recovered anhydrous spent acid is used directly in successive nitrolysis batches with minimal processing. The yield and quality of the hexahydro-1,3,5-trinitro-1,3,5-triazine and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine thus produced is equal to the yield and quality of the legacy process hexahydro-1,3,5-trinitro-1,3,5-triazine and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine employing aqueous workup conditions.
