Beschreibung
Zusammenfassung:	FIELD: inorganic chemistry, chemical technology. ^ SUBSTANCE: invention relates to a method for preparing chlorine dioxide from chlorate ions and hydrogen peroxide in small scales. Chlorate ions, sulfuric acid and hydrogen peroxide are fed into reactor as aqueous solutions wherein they are mixed. Chlorate ions are reduced to chlorine dioxide. Chlorine dioxide-containing product flow is formed in reactor. Flowing water is fed into ejector fitted by jet by spiral or helically. The product flow from reactor passes into ejector and mixed with water and chlorine dioxide diluted solution is formed. Invention provides preparing chlorine dioxide aqueous solution of high concentration and high output. ^ EFFECT: improved preparing method. ^ 18 cl, 3 dwg, 1 tbl, 1 ex
