Experimental Measurement and Correlation of the Solubilities of 2,4-Dichloro-5-methoxypyrimidine in Ethyl Ethanoate, Methanol, Ethanol, Acetone, Tetrachloromethane, and Heptane at Temperatures between (295 and 320) K

Abstract

The solid−liquid equilibrium of 2,4-dichloro-5-methoxypyrimidine was first determined in this article. Using a laser monitoring observation technique, the solubilities of 2,4-dichloro-5-methoxypyrimidine in ethyl ethanoate, methanol, ethanol, acetone, tetrachloromethane, and heptane have been determined experimentally from (295.60 to 316.39, 302.37 to 316.95, 299.44 to 316.61, 297.35 to 311.37, 298.60 to 312.15, and 298.10 to 320.08) K, respectively. The results are correlated with λ−h equation and Apelblat equation. The calculated results show that the correlation of the Apelblat model for six measured systems has less deviation than that of the λ−h equation.
