The incorporation of tritium gas into dioxan, tetrahydrofuran, ethyl acetate, dimethylformamide, dimethylacetamide, dimethylsulfoxide and acetic acid anhydride was studied in the presence of heterogeneous catalysts PdO (Adams), PtO 2 (Adams), Pd/BaSO 4 (10%). For the solvents and catalysts investigated the following dependencies were observed: 1 Wllzbach reaction of the solvents takes only a negligible part in the total incorporation into the solvents. 2 The traces of exchanging impurities in solvents caused much higher incorporation. 3 In the case of non exchanging solvents, practically all the radioactivity incorporated is bound on tritium water.
