The solubility data of epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane in six binary solvents (n-hexane, n-heptane, n-octane, isooctane, cyclohexane, and methylbenzene mixed with various mole fractions of ethyl acetate) was experimentally studied by the gravimetric method at temperatures ranging from 283.15 to 323.15 K under an atmosphere pressure of 0.1 MPa. The results of these measurements were correlated with the modified Apelblat equation, CNIBS/R-K equation, and Jouyban-Acree model. All three models provide a satisfactory correlation.
