Abstract

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:

Wllzbach reaction of the solvents takes only a negligible part in the total incorporation into the solvents.

The traces of exchanging impurities in solvents caused much higher incorporation.

In the case of non exchanging solvents, practically all the radioactivity incorporated is bound on tritium water.
