| description | The invention discloses a technology for recycling and utilizing wastewater produced in oxosynthesis of quinolinic acid by sodium chlorate. The technology comprises the following steps of using the wastewater produced in the oxosynthesis of the quinolinic acid by the sodium chlorate as an initiator, using quinoline, sodium chlorate and copper sulfate as raw materials, and respectively performing oxidizing reaction, alkaline reaction and acidifying reaction, so as to obtain the quinolinic acid. Compared with the prior art, the technology has the advantages that the wastewater produced in the oxosynthesis of the quinolinic acid by the sodium chlorate can be recycled and utilized; the technology is simple, the green and environment-friendly effects are realized, the total yield rate of reaction reaches 82% or above, and the content reaches 99% or above.
本发明公开了种回收利用氯酸钠氧化合成喹啉酸废水的工艺，以氯酸钠氧化法合成喹啉酸产生的废水为引发剂，以喹啉、氯酸钠、硫酸铜为原料，分别经过氧化反应、碱解反应和酸化反应制得喹啉酸。与现有技术相比，本发明可回收利用氯酸钠氧化合成喹啉酸产生的废水，工艺简单，绿色环保，反应总收率可达82%以上，含量在99%以上。 |
