    Cyanuric chloride is an important fine chemical product, has a wide range of uses, it is intermediate of pesticide industry, is the raw material for manufacture of reactive dyes, can do organic industrial production of all kinds of additives, such as fluorescent whitening agent, textile fabrics shrink proof agent, surface active agent is rubber accelerator and defense for manufacturing the raw material of explosives, and medicine, pesticide industry for raw materials of synthetic drugs.
    application range
    Melamine products in the industrial side, with a wide range of uses, the current dosage is used for the production of herbicides, pesticides, reactive dyes and fluorescent dyes. Using cyanuric chloride as raw material for the production of triazine herbicides, such as propazine, prometryne and Prometon, simajine, Simetryn, atrazine killing net, such as atrazine, pesticide anilazine.
    toxicity
    Cyanuric chloride used for pesticide, reactive dyes, fluorescent whitening agent and other additives, is a common activation agent, cheap but highly toxic, mixed with air will form a stimulating smell of gas, the chemicals is toxic, and possibly causing harm to the human body kidney stone.
    Molecular weight 184.5
    Density 1.32g/cm3
    Melting point 146
    Boiling point 194
    Slightly soluble in water,
    Appearance: crystal with pungent smell,
    Packaging: plastic bag, store in a cool, ventilated, dry place, pay attention to fire, sun, moisture.
    Because of its chemical nature is lively, easy to volatile, so the quality is not stable. In the past, the content of melamine was calculated by the condensation of amino benzene sulfonic acid, and the excess of sodium nitrite to the amino benzene sulfonic acid was used to calculate the content of melamine. The hydrolysis of melamine can also cause the result of condensation.
    Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus anticorrosion gas chromatography and overcome the shortcomings of the chemical method. The peak was determined by internal standard method. The analytical method can be used to determine the content of melamine.
                       三聚氯氰是一种重要的精细化工产品,具有广泛的用途,它是农药工业的中间体,是制造活性染料的原料,可做有机工业生产的各种助剂,如荧光增白剂、纺织物防缩水剂、表面活性剂等,是橡胶促进剂和国防用于制造炸药的原料之一,也是医药农药工业用于合成药物的原料。 
      应用范围 
      三聚氯氰产品在工业方面,具有广泛的用途,目前用量较大的是用来生产除草剂 ,农药,活性染料和荧光。用三聚氯氰做原料生产的有三嗪系列除草剂,如扑灭津扑草,扑草通,西马津西草莠灭净莠去津等,农药有敌菌等。 
      毒性
      三聚氯氰用于农药、活性染料、荧光增白剂及其他助剂,是一种常用的活化剂,价廉易得但毒性较大,与空气混合后会形成有刺激性气味的气体,这种化学物品具有毒性,并可能对人体造成肾结等伤害。 
      分子量184.5
      密度1.32g/cm3 
      熔点146℃
      沸点194℃
      微溶于水,
      外观:带有辛辣气味的晶体
      包装:用塑料袋包装,存放于阴凉、通风、干燥处,注意防火、防晒、防潮。

                     由于它的化学性质活泼,易挥发,所以质量不稳定。过去曾用对氨基苯磺酸缩合,过量的对氨基苯磺酸用亚硝酸钠回滴来计算三聚氯氰的含量。由于水解三聚氯氰也能缩合使结果偏高。
                   滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus防腐气相色谱法克服了化学法存在的缺点。用峰高内标法进行测定。本分析方法能较为准确地测定三聚氯氰的含量。
