Safety
  • Health hazard: 急性/慢性危害:该化合物可能是刺激物。(NTP, 1992)
  • reactive group: 卤代芳烃
  • First aid measures: 摄入:如果受害者意识清醒且没有抽搐,给予1-2杯水稀释化学品,并立即呼叫医院或中毒控制中心。如果医生建议,准备将受害者送往医院。如果受害者抽搐或昏迷,不要经口给予任何东西,确保受害者的气道畅通,并将受害者侧卧,头部低于身体。不要催吐。立即将受害者送往医院。(NTP, 1992)
  • Regulatory information: 新西兰EPA化学品状态清单:2,4-二氯苯甲酸:没有单独批准,但可在适当的团体标准下使用
  • fire hazard: 该化学品的闪点数据不可用;但可能是可燃的。(NTP, 1992)
  • fire fighting: 涉及此材料的火灾可以用干化学灭火器、二氧化碳或哈龙灭火器控制。(NTP, 1992)
  • reactivity profile: 2,4-二氯苯甲酸是一种卤代羧酸。羧酸在有碱存在时会释放氢离子。它们以这种方式与所有碱反应,包括有机碱(例如胺)和无机碱。它们与碱的反应称为"中和",伴随着大量热量释放。酸与碱的中和反应产生水和盐。六个或更少碳原子的羧酸在水中的溶解度自由或中等;多于六个碳原子的羧酸在水中的溶解度较低。可溶性羧酸在水中一定程度地解离产生氢离子。因此,羧酸溶液的pH值小于7.0。许多不溶性羧酸与含有...
  • Air and water reaction: 不溶于水。
  • Hazard categories and classifications: 特定靶器官毒性-单次接触 3级 (66.7%)
  • Non-fire leakage response: 储存注意事项:您应在室温下储存此材料。(NTP, 1992)
  • Personal protective equipment (PPE): 建议的呼吸器:在储存、称量和稀释纯测试化学品的地方,佩戴经批准的半面罩呼吸器,配备有机蒸气/酸性气体 cartridges(专门用于有机蒸气、HCl、酸性气体和SO2)和粉尘/雾过滤器。(NTP, 1992)
