Space-filling models of the carbon monoxide molecule

Carbon monoxide reacts with water vapour at high temperatures, forming carbon dioxide and hydrogen; this process has been used as a source of hydrogen for combination with nitrogen in the synthesis of ammonia. With caustic alkalies, carbon monoxide forms alkali formates, which can be converted into either formic acid or alkali oxalates for the production of oxalic acid. With certain metals, carbon monoxide forms compounds called carbonyls, many of which are volatile; this reaction has been used in the purification of nickel. Carbon monoxide and hydrogen are the starting materials in the manufacture of methanol and also are used in the preparation of aldehydes and alcohols from olefins and in making mixtures of liquid hydrocarbons suitable for use as fuels. Gas mixtures containing varying ratios of carbon monoxide and molecular hydrogen are called synthesis gas.

China一氧化碳在高温条件下与水蒸气发生反应，生成二氧化碳与氢气；该过程曾被用作氢气来源，用于与氮气结合合成氨。一氧化碳与苛性碱反应生成碱金属甲酸盐，这类甲酸盐可进一步转化为甲酸或草酸盐，用于制备草酸。一氧化碳可与某些金属结合生成羰基化合物，其中多数具有挥发性；该反应曾被应用于镍的提纯工艺。一氧化碳与氢气是合成甲醇的起始原料，同时也可用于由烯烃制备醛类与醇类，以及制取适用作燃料的液态烃类混合物。按不同比例混合一氧化碳与氢气的气体混合物被称为合成气。贡献者：陈俊杰，开放研究者与贡献者标识符（ORCID）：0000-0001-5055-4309，电子邮箱：[e-mail]，河南理工大学机械与动力工程学院能源与动力工程系，中国河南省焦作市世纪大道2000号，邮政编码454000。
