一氧化碳(CO)是煤、石油等含碳物质不完全燃烧的产物,是易燃高毒气体。在水中的溶解度甚低,易溶于氨水。空气混合爆炸极限为12.5%74%。在空气中不易与其他物质产生化学反应,故可在大气中停留23年之久。在工业生产中接触CO的作业不下70余种,如冶金工业中炼焦、 Carbon monoxide (CO) is a product of the incomplete combustion of carbonaceous materials such as coal and petroleum, and is a flammable and highly toxic gas. Very low solubility in water, soluble in ammonia. The air mixing explosion limit is 12.5% ​​74%. In the air is not easy to produce chemical reaction with other substances, it can stay in the atmosphere for 23 years. Contact with CO in industrial production no less than 70 kinds of jobs, such as metallurgical industry in coking,
