The Heats of Solution of Optically Active Compounds and the Corresponding Racemic Compounds [PDF]
Bulletin of the Chemical Society of Japan, 1980 Abstract The heats of solution of crystalline amino acids and hydroxy acid in water at 298.15 K were measured with a twin isoperibol calorimeter. It was found, as was expected from the theory, that the difference in the heat of solution between optically active compounds and their corresponding racemic compounds was appreciably large ...
