Making Gluconic Acid from D-Glucose by Using Sodium Hypochlorite as Oxidant

用次氯酸钠作氧化剂，氧化Ｄ－葡萄糖制备葡萄糖酸，方法简单，成本低廉，转化率高。研究了ｐＨ值、温度和次氯酸钠浓度对反应的影响。制定了适宜的工艺条件：葡萄糖浓度约为１００ｇ／ｌ，次氯酸钠浓度为２０ｇ／ｌ有效氯，温度为６０℃或次氯酸钠浓度为１０ｇ／ｌ有效氯，温度为８０℃。

Making gluconic acid from D-glucose by using sodium hypochlorite as oxidant is a simple process with low cost and high conversion.Effect ofpH,temperature, concentration of sodium hypochlorite on the reaction is studied.Suitable process conditions are determined that concentration of glucose is about 100 g/l;concentration of sodium hypochlorite,20g/l;reaction temperature,60℃; or,concentration of sodium hypochlorite,10 g/l; reaction temperature,80℃.
