Solubility of stearic acid in ethanol, 1-propanol, 2-propanol, l-butanol, acetone, methylene chloride, ethyl acetate and 95 ethanol from (293 to 315) K

摘要

Solubility of stearic acid in ethanol, 1-propanol, 2-propanol, l-butanol, acetone, methylene chloride, ethyl acetate and 95% ethanol was experimentally determined by the synthetic method from (293 to 315)K. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The solubility of stearic acid in methylene chloride was found to be the highest, and the value in 95% ethanol was the lowest. Results are correlated by semi-empirical equations, which show a good fit to the experimental data.
