| Abstract: | The thermal dissociation of the complex of BF3 with phenetole in the temperature region 172–182° C was studied. It was shown that at water concentrations no greater than 0.01–0.02%, the completeness of thermal dissocation is sufficient to obtain highly concentrated B10. The influence of additions of phenol, which also forms a complex with BF3, upon thermal dissociation of the complex was studied. Experiments on the separation of boron isotopes were conducted on a laboratory column 0.94 m high and 16 mm in diameter. The values of BETT for 15, 25, and 35° C were calculated according to the degree of dissociation in the standard state. The results of the experiments on a laboratory column confirmed the data on thermal dissociation, obtained on a model apparatus.Translated from Atomnaya Énergiya, Vol.22, No.4, pp.297–302, April. 1967. |
