Calorimetric Investigation of the Pyridine — Chloroform Complex

  • Gary L. Bertrand
  • Thomas E. Burchfield


Heats of solution of small amounts of pyridine have been measured in mixtures of chloroform and carbon tetrachloride at 25°C. This data has been interpreted in terms of a complex between chloroform and pyridine with simultaneous solution for Kf and ΔHf% using both the ideal dilute solution approximation and a second approximation which attempts to account for the effects of nonideality. The “best” values determined with the ideal dilute solution approximation are Kf = 0.28 l/mole, ΔHf° = -3.3 kcal/mole; and Kf = 0.28 l/mole, ΔHf° = -2.8 kcal/mole determined with the second approximation.
