Preparation method of trichloroisocyanuric acid

The invention relates to the field of chemical product production, in particular to a preparation method of trichloroisocyanuric acid. The preparation method comprises the steps that, first differentchlorides are formed during a chlorination reaction, and then chlorides other than the trichloroisocyanuric acid are separated from the different chlorides to obtain the pure trichloroisocyanuric acid. After adopting the above technical scheme, the preparation method has the beneficial effects that impurity components contained in calcium hydroxide and cyanuric acid can be removed, and calcium hydroxide is used instead of sodium hydroxide to form the trichloroisocyanuric acid, so that standard production of the trichloroisocyanuric acid is ensured. 一种三氯异氰尿酸的制备方法，它涉及化工产品生产领域，具体涉及一种三氯异氰尿酸的制备方法。所述的方法是首先在氯化反应过程中，生成不同的氯化物，然后从不同的氯化物中分离出三氯异氰尿酸意外的氯化物，从而得到纯净的三氯异氰尿酸。采用上述技术方案后，本发明有益效果为：它能去除氢氧化钙以及氰尿酸所带的杂质成分，使用氢氧化钙代替氢氧化钠生成三氯异氰尿酸，从而能保证三氯异氰尿酸的达标生产。
