THE SEPARATION OF THE BORON ISOTOPES
This method of separating the boron isotopes consists essentially in distilling a dissociable complex in a countercurrent system. A one-step fractionation factor of 1.016 plus or minus 0.002 is obtained using the methyl ether and ethyl ether BF/sub 3/ complexes. The physical and chemical properties and thermal stability of these complexes and other related compounds are discussed in detail. Corrosion data are also included. A method for recovering the boron trifluoride from the ether complexes is given. This method involves the liberation of the ether by formation of the CaF/sub 2/--BF/sub 3/ complex and the subsequent decomposition of this salt complex at an elevated temperature. The various new tests, techniques, and pieces of apparatus devised are described. Other methods of separating the boron isotopes are given and evaluated quantitatively. (auth)
