类别:有毒物质
用途一:广泛用于生产药品、除草剂、植物生长调节剂、染料等
产品特性:碳酰肼(英文Carbohydrazide)又称卡巴肼、1,3-二氨基脲、碳酰肼，常温下为白色细短柱状晶体或白色结晶粉末，难溶于乙醇，极易溶于水，溶解吸热，不溶于醇、醚、苯，由于它是肼的衍生物，具有很强的还原性，无毒，可替代水合肼、肟类。在工业中有较广泛的用途，在水处理领域可用作锅炉水的除氧剂，是当今世界上用作锅炉水除氧的最先进材料，毒性小、熔点高、脱氧效率远远大于目前使用的材料，是理想的安全环保产品；还可用作火箭推进剂的组分；又由于与氮原子相连的氢原子易被其他基团取代，在纺织工业中，还可用作弹性纤维的交联剂、甲醛的捕捉剂、胡萝卜素等色素的抗氧化剂。另外，在含酚杀菌剂的香皂中加入适量的碳酰肼可起到防止变色和酸败的作用。作为化工原料和化工中间体，广泛用于医药、除草剂、植物生长调节剂、染料等行业。
