   The dynamic method which was used for the solubility determination consisted of the saturation of nitrogen with the solute vapor which was then bubbled through a thermostatically controlled flask filled with a definite volume of trichloromethane. After 2 - 3 hours, the solution became saturated and samples were taken periodically (ref. 1). The trichloromethane concentration in the aqueous solution was determined by GLC. On average, 3 - 5 measurements were taken at each temperature.
