FIELD: chemical technology. SUBSTANCE: chlorine dioxide is produced by reduction of sodium chlorate with methanol in an aqueous acid reaction medium at normality of total acid below 7N and reaction medium at boiling point under pressure below atmospheric one at chlorate concentration in medium at least about 2.0M. Under these conditions reaction of by-side product formation is excluded. Also, the chlorine presence in an aqueous solution of chlorine dioxide obtained from this source is excluded. EFFECT: high effectiveness of process. 12 cl, 2 dwg
