F$sup 18$ EXCHANGE BETWEEN FLUOROCARBONS AND SOME FLUORINE-CONTAINING COMPOUNDS
Abstract
Isotopic exchange between solid inorganic fluorides and gaseous fluorocarbons was observed for the first time. Rates of many of these exchange reactions were studied at temperatures as low as 0 deg . Of the inorganic fluorides studied, the exchange was most rapid with alkali metal fluorides. Among the alkali fluorides the rate of the exchange reaction increased markedly with increasing atomic number of the cation. (W.L.H.)

THE RETENTION OF F$sup 18$, PRODUCED BY THE F$sup 19$(n,2n) REACTION, IN FLUOROORGANIC COMPOUNDS. Israel. Atomic Energy Commission, Tel Aviv
Fluoroorrganic compounds were irradiated by fast neutrons from a nuclear reactor; fluoroderivatives labeled with F/sup 18/ were produced and their yield was determined. It was found that labeling yields of fluorodrganic compounds were substantially higher than those of other organic compounds exposed to F/sup 18/ produced extramolecularly, either by the O/sup 16/(H/sup 3/,n) or the F/sup 19/(n,2n) reactions. The extent of substitution of a hydrogen atom by radiofluorine was found to be more than one hundred times that of substitution of a fluorine atom. It was shown that the labeling occurs in the same part of the molecule which originallymore »
