2-methyl-6-acetylnaphthalene%2-methyl-7-acetylnaphthalene%solubility%analytical method
The solubilities of 2-methyl-6-acetylnaphthalene (2,6-MAN) and 2-methyl-7-acetylnaphthalene (2,7-MAN) in n-heptane, n-octane, and n-dodecane were measured, respectively, from 273.15 to 319.15 K using an analytical method. On the basis of the thermodynamics theory of solid-liquid equilibrium, a model was derived to relate the solubilities with temperature. Using the least square method, the parameters of the model, the fusion enthalpies △fusH and the Margules equation coefficients A12 and A21 of 2,6-MAN and 2,7-MAN in n-heptane, n-octane, and n-dodecane-were obtained by regressing the experimental data. The average deviation of the model was 1.70%.
