Solubility of 3-Aminopyridine in Acetone + n-Butyl Acetate from (288.15 to 323.15) K
The solubility of 3-aminopyridine in (acetone + n-butyl acetate) mixed solvents has been measured in the temperature range from (288.15 to 323.15) K by a static analytical method. The concentrations of 3-aminopyridine in saturated solution were analyzed by UV spectrometry. A semiempirical equation was proposed for correlating the experimental data.
