hydrogen sulfide，liquid

物化性质

外观与性状：

无色气体带有强烈的臭鸡蛋气味

密度：

1.19 (15ºC. vs air)

熔点：

−85 °C(lit.)

沸点：

−60 °C(lit.)

闪点：

-82ºC

蒸汽密度：

1.19 (15 °C, vs air)

存储条件/存储方法：

库房通风低温干燥,与硝酸、强氧化剂分开存放

稳定性相关：

1.在有机胺中溶解度极大。在苛性碱溶液中也有较大的溶解度。在过量氧气中燃烧生成二氧化硫和水，当氧气供应不足时生成水与游离硫。室温下稳定。可溶于水，水溶液具有弱酸性，与空气接触会因氧化析出硫而慢慢变浑。能在空气中燃烧产生蓝色的火焰并生成SO2和H2O，在空气不足时则生成S和H2O。有剧毒，即使稀的硫化氢也对呼吸道和眼睛有刺激作用，并引起头痛，浓度达1mg/L或更高时，对生命有危险，所以制备和使用H2S都应在通风橱中进行。

毒理学数据：

1、小鼠、大鼠吸入LC50：634×10-6/1h、712×10-6/1h;大鼠吸入LC50：444×10-6/4h。 硫化氢主要经呼吸道吸收，人吸入（70～150mg/m3）/（1～2h）,出现呼吸道及眼刺激症状, 硫化氢可以麻痹嗅觉神经，吸2～5min后不再闻到臭气。吸入（300mg/m3）/1h,6～8min出现眼急性刺激症状，稍长时间接触引起肺水肿。吸入硫化氢能引起中枢神经系统的抑制，有时由于刺激作用和呼吸的麻痹而导致最终死亡。 在高浓硫化氢中几秒内就会发生虚脱、休克，能导致呼吸道发炎、肺水肿，并伴有头痛、胸部痛及呼吸困难。硫化氢贮存区附近不应有氧化可燃材料、酸或其他腐蚀性材料。避免暴露于高温环境。
