Abstract
22,957. Raschig, F. Nov. 22, 1906, [date applied for under Patents Act, 1901]. Hydrazine is produced by treating a hypochlorite with excess of aqueous ammonia in the cold and then heating before appreciable decomposition of the monochloramine so formed can take place, or by leading chlorine into aqueous ammonia. In an example, a solution of sodium hypochlorite is treated with excess of aqueous ammonia at a temperature below 15‹ C., and the monochloramine thus produced immediately heated, whereby hydrazine hydrochloride is formed, which can be separated as sulphate, by boiling off the excess of ammonia, and adding sulphuric acid. Any other hypochlorite, such as calcium hypochlorite, may replace the sodium salt used above.
