Popis: 1-(3-Bromopropoxy)-4-chlorobenzene is an important intermediate for the manufacture of omoconazole nitrate. The solubilities of 1-(3-bromopropoxy)-4-chlorobenzene in aqueous ethanol solutions were measured within the temperature range of (273.15–303.15) K using a laser monitoring system. For the temperature range investigated, the solubilities of 1-(3-bromopropoxy)-4-chlorobenzene in the aqueous ethanol mixtures increase with increasing temperature. The solubility data were regressed by the Buchowski–Ksiazaczak λh and the modified Apelblat models. The modified Apelblat equation and the Buchowski–Ksiazaczak λh equation provided accurate mathematical representations of the experimental results. The calculated solubilities showed good agreement with the experimental data. The root-mean-square deviations of the modified Apelblat model were lower than those of the Buchowski–Ksiazaczak λh model. This study provided valuable data for the purification of 1-(3-bromopropoxy)-4-chlorobenzene by crystallization.
