摘　　要：考察了由氯酸钠和硫酸在双氧水作用下制备二氧化氯的反应温度、硫酸用量、30%双氧水用量、反应釜液量、压力这5个不同因素对产品转化率的影响,得出了较佳反应条件:反应温度80℃,0.05 mol氯酸钠下硫酸用量0.25 mol、双氧水量0.04 mol,反应液量60 mL,加压。在此条件下氯酸钠转化率能达到98%以上,产品纯度也能达到96%以上。The influence on conversion ratio of the products by five different factors, such as the reaction temperature, sulphuric acid consumption, the consumption of 30 %solution of hydrogen peroxide, liquid amount of the reaction cauldron and reaction pressure, at the reaction of sodium chlorate and sulphuric acid under hydrogen peroxide solution have been studied. The better reaction conditions： reaction temperature is 80 ℃, sulphuric acid consumption is 0.25 mol and hydrogen peroxide amount are 0.04 mol and reaction liquid amount is 60 mL under 0.05 mol sodium chlorate, pressurizing, have been obtained. Under this condition, the ratio of sodium chlorate conversion can reach more than 98%, and the purity of the products can reach more than 96% .
