   Equilibrium established between measured volume of gas and a measured amount of gas-free liquid in a cell fitted with a magnetic stirrer. Amount of gas absorbed estimated from change in volume of gas. Concentration of amine determined by titration. Details in source and Ref. 1.

Source and Purity of Materials:
   1. Commercial sample, purity 99.8 mole per cent.
   2. Reagent grade of guaranteed quality.
   3. Distilled and degassed.

Estimated Errors:
   Solubility: δα = ± 2%. (estimated by compiler)
   Temperature: δT/K = ± 0.2 (estimated by compiler)
