Hydrazine hydrate is recovered from an aqueous solution containing acetone and hydrazine hydrate in proportion of less than 1 mol. of acetone to 1 mol. of hydrazine hydrate, by mixing the solution with an aqueous solution of an alkali metal hydroxide, the acetone hydrazone, formed by reaction ...

Hydrazine hydrate is a colorless liquid containing 63.4% hydrazine (1:1 N2H4:H2O). Aqueous solutions with lower hydrazine contents are also available. A 35% aqueous solution is commonly used for boiler treatment applications.Hydrazine, greater than or equal to 98.5 wt%; water, less than or ...
to more clearly detect the coordination environment in PW-Co3N and Co3N, we carried out wavelet transform (WT) of Co K edge EXAFS oscillations due to the high resolution in both K and R spaces. From the WT contour plots of Co3N (Fig.3c) and PW-Co...
in preparing hydrazine hydrate. CONSTITUTION:In a method for preparing the hydrazine hydrate by reacting hydrazine sulphate and ammonia in the presence of water, the ammonia concn. in a reaction medium is maintained at 25wt% or more always. Thereby, the solubility of ammonium sulphate is ...
Hydrazine hydrate as a hydrogen source has a good effect on nitro reduction, but overuse has environmental toxicity and is prone to over‐hydrogenation, resulting in low selectivity. Herein, we report a magnetically separable Rh/Fe3O4 (1.26 wt%) catalyst containing an optimal Rh content ...

if the dihydrate is desired, the mono-hydrate being stable up to about 300 DEG F. The hydrate may also be added as a 30-60 wt. per cent of oil concentrate. The hydrate may comprise 2 to 40, preferably 5 to 30 wt. per cent of the composition, 20 to 40% of the dihydrate giving...
