Hydrazine sulfate Use and Manufacturing

Methods of Manufacturing

In the urea method, urea, sodium hypochlorite, and liquid alkali are reacted in the presence of potassium permanganate, distilled, and then neutralized with sulfuric acid. The product is cooled and crystallized, filtered, and dried to obtain a finished product of hydrazine sulfate. Its NaOCI+NH2CONH2+2NaOH[KMnO4]→N2H4?H2O+NaCl+Na2CO3N2H4?H2O+H2SO4→N2H4?H2SO4+H2O

Uses

In the gravimetric estimation of nickel, cobalt and cadmium; in the refining of rare metals; as antioxidant in soldering flux for light metals; as reducing agent in the analysis of minerals and slags; in separating polonium from tellurium; in tests for blood; for destroying fungi and molds; in the preparation of hydrazine hydrate.
