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.

丁烷（Butane）或正丁烷（n-butane）属于烷烃类化合物。在室温及常压条件下，丁烷呈气态。它是一种高度易燃、无色的易液化气体，可在室温下快速汽化。丁烷的密度在储存体系中受温度与压力的影响极大。当氧气充足时，丁烷燃烧生成二氧化碳与水蒸气；若氧气供应不足，则可能生成碳或一氧化碳。丁烷的密度大于空气。丁烷与空气混合时的最大绝热火焰温度为1970摄氏度。贡献者：陈俊杰，ORCID：0000-0001-5055-4309，电子邮箱：[e-mail]，河南理工大学机械与动力工程学院能源与动力工程系，世纪大道2000号，焦作市，河南省，454000，中华人民共和国。
