Ball-and-stick models of the butane molecule

Butane or n-butane is an alkane. Butane is a gas at room temperature and atmospheric pressure. Butane is a highly flammable, colorless, easily liquefied gas that quickly vaporizes at room temperature. The density of butane is highly dependent on temperature and pressure in the reservoir. When oxygen is plentiful, butane burns to form carbon dioxide and water vapor; when oxygen is limited, carbon or carbon monoxide may also be formed. Butane is denser than air. The maximum adiabatic flame temperature of butane with air is 1,970 degrees Celsius.

China丁烷（n-butane，正丁烷）属于烷烃。在室温及常压下，丁烷呈气态。它是一种高度易燃、无色且易液化的气体，在室温下可快速汽化。 丁烷的密度极大程度上取决于储存容器内的温度与压力。 当氧气充足时，丁烷燃烧会生成二氧化碳与水蒸气；若氧气供给受限，则可能同时生成单质碳或一氧化碳。 丁烷的密度大于空气。 丁烷与空气混合时的最高绝热火焰温度为1970摄氏度。 贡献者：陈俊杰，ORCID：0000-0001-5055-4309，电子邮箱：[e-mail]，单位：河南理工大学机械与动力工程学院能源与动力工程系，地址：中国河南省焦作市世纪大道2000号，邮编454000
