Carbohydrazinium dinitrate

Abstract

Carbohydrazinium dinitrate, which is formed by adding 2 moles of nitric a (HNO 3 ) to each mole of carbohydrazide (H 2 NHNCONHNH 2 ). This salt is useful as an oxidizer in slurry gun propellants.

What is claimed is: 
     
       1. Carbohydrazinium dinitrate. 
     
     
       2. A slurry gun propellant in which the improvement comprises using carbohydrazinium dinitrate as an oxidizer. 
     
     
       3. A process for preparing carbohydrazinium dinitrate comprising: (1) contacting a mole of carbohydrazide with slightly more than 2 moles of nitric acid wherein the concentration of the nitric acid in water is from about 20 to about 70 percent; and   (2) isolating the product carbohydrazinium dinitrate.   
     
     
       4. The process of claim 3 wherein the concentration of nitric acid in water is from 20 to 50 percent. 
     
     
       5. The process of claim 3 wherein the product carbohydrazinium is isolated in step (2) by removing the water and excess nitric acid at room temperature in a desiccator under vacuum.
