Abstract
The phase and isotopic equilibria between boron trichloride and its solution in perfluorodecalin have been studied. The results of experiments on saturation of perfluorodecalin with boron trichloride, performed at temperatures from 278 to 303 K, indicate high solubility of BCl3 in perfluorodecalin, which varies from 16.09 ± 0.02 to 0.099 ± 0.007 mol BCl3/mol perfluorodecalin. The heat of dissolution of BCl3 in perfluorodecalin is estimated at –(4–6) kJ/mol BCl3, which corresponds to the range of the van der Waals interaction. The single separation factor of boron isotopes during the dissolution of BCl3 in perfluorodecalin was determined based on the results of the isotope analysis of the gas and liquid phases: α = 1.0085 ± 0.0036 and 1.0128 ± 0.0066 at 12 and 5°C, respectively.
