摘要 二氯异氰尿酸钠是一种高效、安全、便于存储运输的固体含氯消毒品,采用NaClO法制备二氯异氰尿酸钠工艺流程相对简单,对设备腐蚀性小,该工艺特别适合建立在氯碱厂附近。通过实验研究,在低温下往NaOH溶液内通Cl2制得高浓度NaClO溶液;将该NaClO溶液和氰尿酸于低温下通Cl2反应,过滤所得的固体经真空干燥后可得w(有效氯)为62%的合格产品。

Abstract: Sodium dichloro-iso-cyanurate (DCCNa) is a kind of solid chlorine-containing product. It is a kind of disinfectant with high efficiency, safety, easier transportation and reservation. The synthesis of sodium dichloro-iso-cyanurate with sodium hypochlorite has comparable advantages such as the simplicity of process and low corrosive, which can be produced near a chlorine alkali factory. An effective two-step way of producing sodium dichloro-iso-cyanurate was carried out experimentally in this paper, in which the available chlorine content of DCCNa can reach about 62%. The first step is to add chlorine into a caustic soda solution at a low temperature to make high concentration sodium hypochlorite. The second step is to add chlorine into the mixture of NaCLO and cyanuric acid. By filtration and drying under vacuum, the qualified mass content of DCCNa product can be manufactured.
