Abstract
A process for producing sodium hypochlorite slurries admixes a hypochlorous acid solution having a concentration of 35 percent or greater by weight of HOCl with sodium hydroxide at a temperature below about 25.degree. C. The reaction produces a slurry of sodium hypochlorite pentahydrate in an aqueous solution of sodium hypochlorite where the sodium hypochlorite is present in a concentration of at least 35 percent by weight of NaOCl. The sodium hypochlorite slurries have improved stability and greatly reduced amounts of sodium chloride. The process for produces high strength sodium hypochlorite compositions of high purity having improved yields and reduced product decomposition.
