Safety
  • Health hazard: 急/慢性危害:该化合物在严重受热或加热到极端温度时可能发生剧烈反应。(NTP, 1992)
  • reactive group: 胺类,芳香族
  • First aid measures: 食入:不要催吐。如果受害者意识清醒且没有抽搐,给予1-2杯水稀释化学物质,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,确保受害者的气道通畅,让受害者侧卧,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化学品清单状态:N,N'-二乙基-N,N'-二苯基脲:没有单独批准,但可作为符合团体标准的产品中的组分使用。它不被批准作为化学品单独使用。
  • fire hazard: 该化学品可燃。(NTP, 1992)
  • fire fighting: 涉及此化学品的火灾应使用二氧化碳、干化学灭火器或哈龙灭火器进行控制。(NTP, 1992)
  • reactivity profile: N,N'-二乙基碳酰苯胺是一种酰胺。酰胺/酰亚胺与偶氮和重氮化合物反应生成有毒气体。酰胺与强还原剂反应形成易燃气体。酰胺是非常弱的碱(比水弱)。酰亚胺的碱性更弱,实际上与强碱反应形成盐。也就是说,它们可以作为酸反应。将酰胺与脱水剂如P2O5或SOCl2混合会生成相应的腈。这些化合物的燃烧产生氮的混合氧化物(NOx)。该化合物与酸和氧化剂不相容。当严重受热或暴露在极端温度下时,该化学物质会发生剧烈反应。(NTP, 1992)
  • reactive alarm: 爆炸性
  • ecotoxicity value: USDA APHIS化学影响:collection=usda_chemeffect&query_type=synonym&query='^85-98-3$'
  • Air and water reaction: 不溶于水。
  • Hazard categories and classifications: 水生慢性 3 (100%)
  • Non-fire leakage response: 储存注意事项:您应将此材料存放在冰箱中。(NTP, 1992)
  • Personal protective equipment (PPE): 推荐呼吸器:在称量和稀释纯测试化学品时,佩戴NIOSH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)
