Andrzej Maczynski Solubility, Solubility data series Saturated solutions of tritum labeled (2) in (1) were prepared in two ways. In the first, nitrogen was passed through the vessel with (1) and frozen. In the second, about 500 mL of (1) and 1 mL (2) were stirred. The concentration of (2) in (1) was calculated from scintillation measurements. The International Union of Pure and Applied Chemistry Zel'venskii, Ya. D.; Efremov, A. A.; Larin, G. M.; Chem. Technol.
