Estimation of the chemical form and the boiling point of elementary astatine by radiogas-chromatography
Description
After astatine (0) was mixed with 131I2 containing carrier I2, the sample was analyzed by means of radiogaschromatography and the peaks due to I2, AtI and At2 were observed. Further, the boiling points were estimated from the retention volume in terms of the semi-empirical theory on gas chromatography. The boiling points of I2, AtI and At2 were 457 +- 2,486 +- 2 and 503 +- 3K, respectively. The boiling point of At2 obtained in the present work is far smaller than that expected by the extrapolation of lighter halogens. (orig.)
