Solubilities of 2,4-Dinitroanisole in Pure Organic and Mixed Organic Solvents at Temperatures between 283.15 and 313.15 K

The solubility of 2,4-dinitroanisole (DNAN) was measured in nine commonly used pure organic solvents, including ethanol, acetone, ethyl acetate, n-propanol, i-propanol, butyl alcohol, cyclohexanone, toluene, and cyclohexane, and four binary mixed solvents between 283.15 K and 313.15 K at atmosphere pressure by the gravimetric method. The solubility of DNAN showed a temperature dependence in all test solvents. The order of the solubility of DNAN was acetone ≈ cyclohexanone > ethyl acetate > n-propanol + acetone ≈ ethanol + acetone ≈ toluene > ethanol > n-propanol > water + acetone > n-butanol + acetone > n-butanol ≈ i-propanol > cyclohexane. The experimental mole fraction solubility data were correlated with the modified Apelblat equation, Yaws equation, and van’t Hoff equation. The correlation showed good agreement with the experimental results, and the largest value of the root-mean-square deviation was 11.88 × 10–4. All of the obtained results would benefit the purification and crystallization of DNAN, which would extend its applications in the field of explosives.
