摘要: 2-Chloro-5-chloromethylpyridine is a crucial intermediate of pesticides.Its solid-liquid equilibrium data will provide essential support for industrial design and further theoretical studies.The solubilities of 2-chloro-5-chloromethylpyridine in water,methanol,ethanol,ethyl acetate,acetone,trichloromethane and toluene at different temperatures were measured using the synthetic method by a laser monitoring observation technique. The solubility data were correlated with the modified Apelblat equation and Wilson equation.The calculated values were in good agreement with the experimental values.
