Marie C. Haulait-Pirson Solubility, Solubility data series A method of gravimetric absorption monitored by tritium tracer was used. (1) was equilibrated with a slight excess of titrated water by shaking over a period of at least 8 hr in a thermostat. The phases were allowed to separate for at least 16 hr and then were sampled for tritium analysis. Most of the (1) phase was weighed into a boiling flask of a closed distillation system and then distilled through a magnesium perchlorate weighing tube. The magnesium perchlorate was then dissolved for measurement of its tritium content by liquid scintillation counting with a Packard Tri-Carb Scintillation Spectrometer.
