(1) and an appropriate amount of fine dry (2) were placed in an ampoule, which was sealed, and then maintained at constant temperature for 50 hours. After that time the ampoule was opened and the equilibrium concentration determined gravimetrically. The International Union of Pure and Applied Chemistry Kushchenko, V. V.; Litvinov, L.
