Open publisher page 0 citations

Abstract

Cellulose,sodium chlorate and sulfuric acid are used as raw material for preparing chlorine dioxide in a large num- ber of experiments.It is found that when the ration in mole between sodium chlorate and cellulose is 20:1 ,concentration of sulphuric acid is 5 mol·L~(-1),the temperature is 90℃and the reacting time is 90 minutes,the yield of chlorine dioxide can reach 93.60%.So reducing sodium chlorate by using cellulose as a reducing reagent is a new method of preparing chlorine dioxide.
