Abstract:

The heat of dissociation of the complex formed by cyclotetramethylenetetranitramine and dimethylformamide, HMXDMF, was measured in DMF. The difference in crystal energy between alpha HMX and beta HMX as measured in acetone is 0.6 kcalmole. A mechanism for the solution of HMX in DMF is proposed. The energies measured suggests that the bond forming the complex is due to van der Waals forces. It is also suggested that the dipole dipole interaction makes a significant contribution to the bond energy.
