Abstract
The procedure is described and the results of the determination of the vapor pressure of samples of high-percentage tritium water (containing 83.4 and 98.1 mole % T2O) in the 12–95 °C temperature range are given. To calculate the pressure of the gaseous products of the radiolysis of water and nuclear transformations the measurements were carried out by the static method at two different volumes of the apparatus. It was found that the boiling points of HTO and T2O are 100.8 and 101.6 °C, the heats of vaporization at these temperatures are 9.9 and 10.0 kcal/mole, and the standard entropies are 19.3 and 19.0 units, respectively.
