Safety
  • DOT label: 有毒
  • Health hazard: 有毒和/或腐蚀性;吸入、摄入或皮肤接触该物质可能导致严重伤害或死亡。接触熔融物质可能导致皮肤和眼睛严重烧伤。避免任何皮肤接触。火灾可能产生刺激性、腐蚀性和/或有毒气体。消防或稀释水产生的径流可能具有腐蚀性和/或毒性,并造成环境污染。(ERG, 2024)
  • Hazard summary: 可能引起刺激;食入有害;可能引起敏感个体的过敏反应;[Sigma-Aldrich MSDS] 参见4-硝基苯甲酸和3-硝基苯甲酸。
  • reactive group: 硝基、亚硝基、硝酸盐和亚硝酸盐化合物,有机
  • 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: REACH 注册物质:状态:活跃 更新:28-04-2014 https://echa.europa.eu/registration-dossier/-/registered-dossier/5345
  • fire hazard: 有关该化学品的闪点信息不可用。它可能是可燃的。(NTP, 1992)
  • fire fighting: 涉及该化合物的火灾可用干粉、二氧化碳或哈龙灭火器控制。(NTP, 1992)
  • reactivity profile: 4-甲基-3-硝基苯甲酸是一种硝基羧酸。羧酸在存在碱的情况下会释放氢离子。它们以这种方式与所有碱(例如胺类)和无机碱反应。它们与碱的反应,称为“中和反应”,伴随着大量热量的释放。酸和碱之间的中和反应产生水和盐。含有六个或更少碳原子的羧酸可自由或中度溶于水;含有六个以上碳原子的羧酸在水中微溶。可溶性羧酸在水中会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...
  • Isolation and evacuation: 火灾:如果涉及罐、铁路罐车或公路罐车,应在所有方向上隔离800米(1/2英里);同时,考虑在所有方向上初始疏散800米(1/2英里)。(ERG, 2024)
  • Air and water reaction: 不溶于水。
  • Hazard categories and classifications: STOT SE 3 (12.8%)
  • 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)
