Butane and liquefied gas are common household gas products. Although they are all a type of liquefied petroleum gas (LPG), there are certain differences in molecular structure, properties, and applications

Butane and liquefied gas have different molecular structures. The chemical formula of butane is C4H10, which belongs to the alkane class of compounds. It is a colorless, odorless, and volatile liquid that is easily converted into gas at room temperature. Liquefied gas is a mixture of propane and butane. The chemical formula of propane is C3H8, while the chemical formula of butane is as described earlier. Therefore, liquefied gas not only contains butane, but also other components such as propane

Butane and liquefied gas differ in their properties. Butane has a lower combustion temperature and can be used for cooking and heating. Liquefied gas has a higher combustion temperature and is suitable for high-temperature heating, such as welding. In addition, butane has relatively good combustion performance and produces less carbon dioxide and water vapor during combustion. Liquefied gas generates more carbon dioxide and water vapor during combustion. This is also one of the reasons why liquefied gas combustion produces more water vapor and is prone to moisture indoors

There are some different selection suggestions for the use of butane and liquefied gas. Due to the low combustion temperature of butane, it is suitable for cooking and heating in stoves, but not suitable for high-temperature heating. Therefore, for general household users, butane is a more suitable choice. For industries and fields that require high-temperature heating, such as barbecue shops, foundries, etc., liquefied gas is more suitable. In addition, the cost of liquefied gas is relatively low and its service life is short. Butane has a relatively high cost but a longer service life. Therefore, if economic conditions permit, butane can be chosen

In summary, although butane and liquefied petroleum gas belong to different forms of liquefied petroleum gas, there are certain differences in molecular structure, properties, and applications. When choosing to use it, one can make judgments based on specific needs and economic conditions. I hope this article is helpful for readers to understand and choose butane and liquefied gas.
