Radiolyse de l'ammoniac liquide en milieu basique—I: Influence du pH

Abstract

In liquid ammonia containing amide, the yield of hydrazine is higher and the yield of hydrogen and nitrogen smaller than in neutral solution. The stationary concentration of N 2H 4 is much higher than in neutral or acid solution, attaining 0·10 mol dm −3 KNH 2. The discussion shows that the yield variations with pH have their origin in the replacement of H atoms by ρ am -, the former being able, as opposed to the second, to react with N 2H 4 to form H 2. The initial yields G N 4 H 4 = 0·30 and G NH = 0·34 are the same as in neutral solution.
