摘要：

The solubilities of 2(2,4,6-trichlorophenoxy)ethyl bromide in methanol, ethanol, propanol, isopropanol, acetone, acetonitrile, and n-heptane were measured using the analytical stirred-flask method over the temperature range from (278.2 to 323.2) K. The results showed that acetone had highest solubilities and solubilities of 242,4,6- trichlorophenoxy)ethyl bromide in different solvents increase with temperature. The experimental data were regressed by the lambda h equation and the modified Apelblat equation. The calculated solubilities showed good agreement with the experimental data and had acceptable precision for industrial applications. In addition, the melting point of 2(2,4,6-trichlorophenoxy)ethyl bromide determined by differential scanning calorimetry (DSC) was 324.05 K, and the melting enthalpy was 79.02 J.g(-1). The results of DSC also indicated that 2-(2,4, 6-trichlorophenoxy)ethyl bromide did not have any enantiotropically related polymorphs.
