The behavior in hydrolysis of uranium monocarbonitrides (UC<SUB>1-x</SUB>N<SUB>x</SUB>) of various compositions has been studied and compared with the hydrolysis of UN and UC. The products of the hydrolysis were found to be H<SUB>2</SUB>, CH<SUB>4</SUB>, C<SUB>2</SUB>H<SUB>6</SUB>, C<SUB>3</SUB>H<SUB>8</SUB>, NH<SUB>3</SUB>, CH<SUB>3</SUB>NH<SUB>2</SUB>, C<SUB>2</SUB>H<SUB>5</SUB>NH<SUB>2</SUB> and C<SUB>3</SUB>H<SUB>7</SUB>NH<SUB>2</SUB>, and did not vary qualitatively with the composition (C/N), while quantitatively their relative amounts, and also the temperature of formation were found to be markedly affected by the composition. The more carbon-rich compounds tended to be easily hydrolyzed below 100°C, as in the case of UC, while the amenity to hydrolysis was found significantly weaker with the nitrogen-rich compounds, as with UN. The hydrolysis of carbonitrides is characterized by the formation of amines, which were found particularly abundant in the case of UC<SUB>0.53</SUB>N<SUB>0.47</SUB> (C:N=1:1). <BR>To elucidate the mechanism of the reaction under study, a mechanically mixed specimen of UN and UC was hydrolyzed. No amines were observed to be generated in this case. This finding was considered suggestive of two plausible mechanisms, namely, mutual interaction between free radicals located within short distances of each other, and the hydrogenation of skeletons such as C-C-N.
