坚膜剂2,4-二氯-6-羟基均三嗪钠盐的另法制备

A Novel Preparation Method of the Hardener 2,4-dichloro-6-hydroxy-s-triazine Sodium Salt

用偏硼酸钠(NaBO2)制备坚膜剂2,4-二氯-6-羟基均三嗪钠盐,坚膜作用与用NaHCO3法的基本相同,但该产品能在室温下自然保存。

The hardener 2,4-dichloro-6-hydroxy-s-triazine sodium salt can be prepared by using Sodium Metaborate instead of Sodium Bicarbonate, the hardening effects of the products prepared by both methods are basically the same, but the product yielded by the new method can be kept well at room temperature.
