A study of tritium labelling by solid-state catalytic reductive dehalogenation


A reaction mechanism is proposed for tritium labelling by the SCRD method /solid-state catalytic reductive dehalogenation/ based on hydrogen spillover. A model system /palladium membrane with a layer of the original organic compound/ is used for a kinetic study of the debromination of 5-bromouracil and the isotope exchange of α-alanine at pressure of 0.07–20 kPa. A kinetic model is considered for the spillover stoppage due to the contamination of penetration centres by the reaction product. Other possible causes of the spillover stoppage are discussed.
