The solubility of epsilon-CL-20 was assessed in 12 organic solvents by the equilibrium method at temperatures ranging from 278.15 to 318.15 K and 0.1 MPa. The order of the solubility of epsilon-CL-20 was ethyl acetate > butyl acetate > triethyl-orthoformate > methanol > ethanol > propanol > 1-butanol > isopropyl alcohol > m-xylene > chloroform > toluene > cyclohexane. The modified Apelblat equation was used to correlate the experimental solubility values at these temperatures in these solvents and the results showed good agreement with the experimental values.
