释义

Carbonic Oxide

中文百科

一氧化碳 Carbon monoxide

(重定向自Carbonic Oxide)
MOPITT(对流层污染测量仪)在2000年检测全球一氧化碳的含量

一氧化碳,分子式CO,是无色、无嗅、无味、剧毒的无机化合物气体,比空气略轻。在水中的溶解度甚低,但易溶于氨水。空气混合爆炸极限为12.5%~74%。 一氧化碳是含碳物质不完全燃烧的产物。也可以作为燃料使用,煤和水在高温下可以生成水煤气(一氧化碳与氢气的混合物)。有些现代技术,如炼铁,还是会产生副产品的一氧化碳。一氧化碳是可用作身体自然调节炎症反应的三种气体之一(其他两种是一氧化氮和硫化氢)。

由于一氧化碳与体内血红蛋白的亲和力比氧与血红蛋白的亲和力大200-300倍,而碳氧血红蛋白较氧合血红蛋白的解离速度慢3600倍,当一氧化碳浓度在空气中达到35ppm,就会对人体产生损害,会造成一氧化碳中毒(又称煤气中毒)。

Carbon monoxide 一氧化碳

(重定向自Carbonic Oxide)
Monthly averages of global concentrations of tropospheric carbon monoxide at an altitude of about 12,000 feet. Data were collected by the MOPITT (Measurements Of Pollution In The Troposphere) sensor on NASA’s Terra satellite.[39]

Energy level scheme of the σ and π orbitals of carbon monoxide

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to hemoglobic animals (including humans) when encountered in concentrations above about 35 ppm, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions. In the atmosphere, it is spatially variable and short lived, having a role in the formation of ground-level ozone.
