The production of carrier-free gallium-67 at external target of the 1.2M cyclotron is described. It was produced by bombardment of natural copper with 26.8 MeV a and natural zinc with 13.4 MeV deuterium, gave thick-target yields of 165μCi/μAh and 350μCi/μAh, respectively. Radiochemical separation of carrier-free gallium-67 from target was carried out by isopropyl ether extraction. Gallium-67 citrate injection was prepared by sodium citrate leaching.

The reactions of bound antioxidants, 2-(N-isopropyl-N' -phenyl-p-phenyldiamine) -4, 6-dithiol-S-triazine(IPPST)with butadiene rubber (BR) in sulfur, peroxide and high performance curing systems were studied respectively. The high reactivity, good aging resistance and extracting resistance of IPPST in BR vulcanizates were confirmed by IR, 1H-NMR, DSC and mechanical properties test.
