A procedure for estimating the crystal densities of organic explosives
Existing methods of density prediction, which primarily involve the summation of appropriate atomic or group volumes of parts of a molecule, yield what we call a ''normal'' density for a particular chemical composition. However, the compounds of most interest as military explosives often have densities significantly above the norm and predicted densities for memebers of this group frequently are substantially underestimated. A new procedure has been developed that allows a possible crystal packing arrangement for a molecular to be determined, from which a crystal density, usually accurate to within 2% can be calculated. The technique consists of three parts: determinationmore »
