Octahydro-1, 3, 5, 7-tetranitro-1, 3, 5, 7-tetrazocine (TAT) was produced by condensation of acetonitrile and trioxane as a low cost precursor for the production of 1, 3, 5, 7-tetranitro- octahydro-1, 3, 5, 7-tetrazocine (HMX). However, 1, 3, 5-triacetyl-hexahydro-s-triazine (TRAT) was also produced as a byproduct. To develop an efficient and economical method for the separation of TAT and TRAT, the solubilities of TAT and TRAT in ethyl acetate, ...
