An apparatus and method for generating chlorine dioxide. Reagents are introduced into the lower end of a reaction column through 'V' inlets. The reagent column surrounds a center column through which motive fluid moves upwardly into a nozzle and venturi throat to produce a zone of reduced pressure at the upper end of the reaction column. The reagents move upwardly through the column interacting throughout 360.degree.. Reaction product exits the generator through the venturi throat.

Chlorine dioxide generator

Process for the preparation of saturated aqueous solution of chlorite salts by the controlled reaction of chlorine dioxide with a reducing agent under reduced pressure to form chlorous acid. The chlorous acid is reacted with an aqueous solution of base to form an aqueous solution chlorite salt and the aqueous solution is recycled through the process. The process is rapid, economical and is conducted in a generator which is significantly smaller than equipment currently used for production of chlorite salts.
