Abstract

Chloramine is produced by adding sodium hypochlorite to ammonia in the presence of an acceptor, which is an acid or a water-soluble acid salt or a water-soluble neutral salt containing calcium, magnesium or zinc cations. The acceptor is in a concentration sufficient to react with at least 25% of the sodium hydroxide produced in this reaction. Ammonium chloride and hydrochloric acid are preferred acceptors, and a sequestering agent such as glue or gelatin may be added. The reaction is carried out between - 10 DEG and + 20 DEG C. The chloramine solution may be reacted with ammonia and an alkali metal hydroxide at a temperature between 20 DEG and 140 DEG C. to form hydrazine.ALSO:Primary and secondary amines are reacted with chloramine solution and an alkali metal hydroxide to form substituted hydrazines, at a temperature between 20 DEG and 50 DEG C. The amine can contain alkyl, cycloalkyl or heterocyclic radicals, those with alkyl groups having from 1 to 6 carbon atoms being particularly suitable. Examples given are methylamine, dimethylamine and piperidine. The chloramine solution is prepared by adding sodium hypochlorite to ammonia in the presence of an acceptor, which is an acid, a water-soluble acid salt, or a water-soluble neutral salt containing calcium, magnesium or zinc cations.
