Degassed solvent was injected at a constant rate into the absorption spiral by means of a syringe-pump while the gas was displaced by mercury using a mechanical elevating device for a mercury bottle, at a rate required to keep the gas pressure constant. Readings of the volume of solvent required to achieve saturation were obtained from which the solubility was calculated. Constant temperature fluid was circulated through a jacket enclosing the burettes and absorption spiral. The International Union of Pure and Applied Chemistry Sahgal, A.; La, H. M.; Hayduk, W.; Can.
