• MSDS 信息:氰尿酰氯(108-77-0).msds
• 概述:三聚氯氰又名氰尿酰氯，具有强烈刺激性氯气味的白色结晶，对皮肤有腐蚀性，对眼有刺激性和催泪性。熔点145℃，沸点190℃，UVλmax241nm(乙醇)。溶于无水乙醇、乙醚、氯仿、乙酸和丙烯腈，难溶于冷水。三聚氯氰与水作用冷却时缓慢，加热时很快水解为氰尿酸(C3H3O3N3)和盐酸，产物都是比较易溶于水的，所以可以使用萃取的方法分离。与浓硝酸和浓硫酸在室温下作用部分转化为氰尿酸，与醇钠作用得正氰尿酸的三酯，也能与氨、胺、酚等起作用。 制法：由无水氢氰酸与干燥氯气在日光中(或在无水乙醚中)反应，或由氰尿酸与过量五氯化磷加热而得。 用途：三聚氯氰是生产高效、低毒的均三氮苯类除草剂、杀虫剂的重要中间体，也是生产活性染料的中间体，可用作合成树脂、橡胶、聚合物防老剂、氰醛树脂、照相感光剂、荧光增白剂、粘合剂、多种药用药物的原料。 近年来，我国三聚氯氰消费增长较快，1998～2004年表观消费量的年均增长率约为32.2％，2005年三聚氯氰需求量达到5.0万吨，据预测，2007～2012年三聚氯氰将以年均6.0％的增长率保持快速增长，市场前景十分看好。由于三聚氯氰后续产品多，市场需求量大，各国相关企业和研究机构一直在持续开发其下游产品、开拓三聚氯氰应用领域。因此，由三聚氯氰衍生的新产品不断涌现，其市场需求量还将进一步扩大。 三聚氯氰参与的相关化学反应： 由2-氨基-4-硝基苯酚重氮化，与H酸偶合，经铬、钴络合处理后，先与三聚氯氰缩合，再与氨水缩合而得活性黑K-BR。主要用于棉布、涤/棉布的印花。 以三聚氯氰为原料，在三氯乙烯溶液中，在20～30℃下，与乙胺反应，生成2，4-二氯-6-乙氨基-1，3，5-三嗪，再与氨反应，生成2-氨基-4-氯-6-乙氨基三嗪，再与2- 氯-2-甲基丙腈反应，可生成选择性除草剂草净津，用于玉米田间防除一年生或多年生窄叶或宽叶杂草。 以上
• 方法一:三聚氯氰的生产通常由氯氰制备和氯氰聚合两个过程组成。生成氯氰的方法有多种，诸如硫氰酸甲酯和氯的合成法、氢氰酸溶于氯仿通入氯气的合成法、氢氰酸法、氰化钠法、尿素法、氢氰酸与氯气的直接氯氰化法等，目前工业上生产三聚氯氰一般采用氰化钠及氢氰酸为原料的两种方法。1.氰化钠法 用氰化钠为原料与氯气反应生成氯氰，再聚合生成三聚氯氰经急冷、结晶制得产品。原料消耗定额：氰化钠1073kg/t、氯气1700kg/t。2.氢氰酸法 以氢氰酸为原料与氯气反应生成氯氰，再聚合生成三聚氯氰，经急冷、结晶制得产品。原料消耗定额：氢氰酸500kg/t、氯气1200kg/t。
