In pulp bleaching, water treatment, and other applications, chlorine dioxide has the advantages of high‐efficiency oxidation. The technology of preparing chlorine dioxide by combination reduction is widely used in domestic papermaking enterprises. However, in the actual production process, the chlorine dioxide solution still contains a small amount of chlorine gas and methanol. Therefore, here, the process of preparing chlorine dioxide by combination reduction was further optimized to improve the utilization rate of raw materials and product purity. In this study, a new production process of chlorine dioxide with lower cost, higher purity, no pollution, and good security and reliability was developed.

联合还原法制备高纯二氧化氯

在纸浆漂白，水处理和其他应用中，二氧化氯具有高效氧化的优势。联合还原法制备二氧化氯的技术在国内造纸企业中得到了广泛的应用。但是，在实际生产过程中，二氧化氯溶液仍含有少量的氯气和甲醇。因此，在此进一步优化了通过组合还原制备二氧化氯的工艺，以提高原料利用率和产品纯度。在这项研究中，开发了一种成本更低，纯度更高，无污染且安全性和可靠性良好的新的二氧化氯生产工艺。
