Abstract
The kinetics of decomposition of hydrazine and hydroxylamine in concentrate d nitric acid at 70 degrees C establish a critical concentration [hydrazine ] approximate to 5 x 10(-4) mol dm(-3) below which a rapid autocalalytic de composition of hydroxylamine occurs; this corresponds to the rate of nitrit e scavenging by hydrazine balancing the rate of N2O4 formation.
