Preparation of CH/sub 3/Br and CH/sub 2/BrCOOH by direct 10/sup 12/ neut/ cm/sup 2/sec irradiation of Br/sub 2/ + CH/sub 3/COOH showed better results than chemical synthesis. The method resulted in high yield and low impurity (4%). The carrier-free CH/sub 3/Br and CH/sub 2/BrCOOH are produced by the second atom reaction of Br/sup 82/ with CH/sub 3/COOH recoil. The tabulated data showed that with high bromine concentration in the initial mixture the yield of CH/sub 2/ BrCOOH diminishes but the absolute activity increases to 14 C at st run. Concent 0.1 to 0.2 M then remains unchanged. The yield of CH/sub 3/Br from the second reaction of Br/sup 82/ recoil atoms with CH/sub 3/COOH molecules is <30%; however, with increased bromine the concentration increases continuously, explaining the easy exchange of bromine during CH/sub 3/Br gas filtration through the initial mixture at 80 un. Concent 85% : CH/sub 3/ + Br CH/sub 3/Br + Br. The exchange reaction was used for supplementary purification of CH/sub 3/Br from Br/sub 2/. (R.V.J.)
