Product introduction
物理描述 | 乙二酸乙酯为无色液体。略重于水且不溶于水。因此沉于水中。可能刺激皮肤和粘膜;经口摄入可能轻度有毒;火灾中可能释放刺激性烟雾。蒸气远重于空气。用作塑料溶剂以及香水和制药的制造。

Safety
  • DOT label: 有毒
  • Health hazard: ERG2024, 指南156(乙二酸乙酯):· 灭火或稀释水的径流可能具有腐蚀性和/或毒性,并造成环境污染。
  • Hazard summary: 强皮肤和粘膜刺激物;[Hawley] 眼刺激物;[eChemPortal: ERMA; ESIS] 刺激物;[MSDSonline]
  • reactive group: 酯类、硫酸酯、磷酸酯、硫代磷酸酯和硼酸酯
  • First aid measures: ERG2024, 指南 156 (乙二酸乙酯):在加拿大,可能需要为此产品制定应急响应援助计划(ERAP)。请查阅运输文件和/或“ERAP”部分。
  • Harmful effect: 神经毒素 - 急性溶剂综合征
  • fire hazard: ERG2024, 指南 156 (草酸乙酯): · 容器受热或被水污染时可能爆炸。
  • fire fighting: FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. (ERG, 2024)
  • Fire potential: 一些具有较高闪点的酯类,如...乙二酸乙酯,在室温下不那么危险。然而,它们仍易被点燃,作为易燃液体,必须防止点火源与其接触。
  • Fire extinguishing procedure: 泡沫、二氧化碳、干粉
  • Preventive measures: 应测试大气中是否存在易燃蒸气,只有在测试确定容器安全后才能施加热量。/酯类/
  • reactivity profile: 乙二酸乙酯是一种酯。酯与酸反应会释放热量,同时生成醇和酸。强氧化性酸可能会引起剧烈反应,该反应放热足以点燃反应产物。酯与苛性溶液的相互作用也会产生热量。将酯与碱金属和氢化物混合会生成易燃的氢气
  • Isolation and evacuation: 疏散:ERG2024, 指南 156 (草酸乙酯): · 如果涉及储罐、铁路罐车或公路罐车发生火灾,应在所有方向上隔离800米(1/2英里);同时,也应考虑在所有方向上初始疏散800米(1/2英里)。
  • DOT ID and Guide: 2525 156
  • NFPA Hazard Classification: NFPA不稳定性等级:0 - 本身在火灾条件下通常稳定的物质。
  • Human toxicity extract: 对皮肤和粘膜有强烈刺激性,尤其经食入。
  • Other safety information: 化学品评估:IMAP评估 - 草酸盐酯(C1-C4):人类健康二级评估
  • Air and water reaction: 不溶于水。
  • Hazard categories and classifications: 眼刺激。2
  • Non-human toxic extract: 大鼠经口LD50为0.4-1.6 g/kg,呼吸紊乱和肌肉抽搐是显著症状。大鼠口服400 mg/kg剂量后,可见大量肾草酸盐沉积和肾小管扩张。
  • Non-fire leakage response: 少量泄漏:用干土、干沙或其他不燃材料覆盖,然后盖上塑料布以减少扩散或与雨水接触。使用干净、无火花工具收集材料并将其放入松散覆盖的塑料容器中以便后续处置。(ERG, 2024)
  • Personal protective equipment (PPE): 应备有眼部和面部防护及呼吸防护装备...以防在发生与这些酯类相关的紧急情况(例如液体严重泄漏)时接触。/酯类/
  • Possible routes of human exposure: 工业中尚无草酸乙酯致死中毒的病例,但其潜在的毒性作用必须予以考虑。
  • Protective Action Standards (PAC): PAC-3: 79 [mg/m3]
  • DOT Hazard Classification: Placard/Label(s)
  • Toxic Combustion Products: 燃烧时将释放有毒烟雾
  • Accidental Release Measures: 泄漏或溢出:ERG2024,指南 156 (草酸乙酯):· 使用清洁、无火花的工具收集物料,并将其放入松散覆盖的塑料容器中以便后续处置。
  • Explosion limit and latent risk: 在高温下运行的工艺容器、干燥炉等设备中,任何酯类都可能释放出足够的蒸气,与空气形成爆炸性混合物。/酯类/
  • Emergency Response Planning Guidelines: 应急响应:ERG2024,指南156(乙二酸乙酯):· 始终远离直接接触火焰的储罐。
  • Exposure Control and Personal Protection: 防护服:ERG2024,指南156(乙二酸乙酯):· 结构消防员防护服提供热防护,但仅提供有限的化学防护。
