The Chemical Effects of Storing Hydrazine Containing Carbon Dioxide Impurity in Stainless Steel Systems

Abstract:

The effect of low concentrations less than 250 ppm of dissolved carbon dioxide carbazic acid on the rate of decomposition of hydrazine, in both stainless steel and glass vessels, has been investigated. In a stainless steel vessel at 60 C the rate of hydrazine decomposition was found to be directly proportional to the total concentration of added carbon dioxide above about 20 ppm while for a glass vessel at 51 C the relationship between concentration of added carbazic acid and hydrazine decomposition rate is best interpreted in terms of a Langmuir isotherm equation. The preparation of some carbazato-complexes of iron, chromium and nickel, such as may be formed during the hydrazinecarbon dioxide corrosion of stainless steel, is also reported. Additions of small amounts of dicarbazatodihydrazineiron 11 to hydrazine in a glass vessel had no measurable effect on the decomposition rate at 43 C. Tricarbazatochromium 111 dihydrate was found to be similarly inactive while the principal nickel carbazato- complex is completely insoluble in hydrazine.
