2017年9月3日 · Butane and isobutane are hydrocarbon compounds that can be found in crude oil as minor constituents. They are small alkane compounds that are called paraffin fraction of petroleum refining. Although they have the same chemical formula and the same molar mass, they are different in several ways.

Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC (CH 3) 3. It is an isomer of butane. Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom.

Butane and isobutane have similar chemical formulas, C 4 H 10, but their structures differ. Butane consists of a straight chain of four carbon atoms, whereas isobutane contains a branched structure with three carbon atoms in a chain and one carbon atom branching off.

2023年12月21日 · Butane (C₄H₁₀) is an alkane with a linear structure of four carbon atoms linked consecutively. Isobutane, however, also known as methylpropane, is a structural isomer of butane with a branched chain, where one carbon atom is connected to three others at the central point.

异丁烷，又名2-甲基丙烷，是一种有机化合物，化学式是C4H10，常温常压下为无色可燃性气体。 微溶于水，可溶于乙醇、乙醚等，与空气形成爆炸性混合物，主要存在于天然气、炼厂气和裂解气中，经物理分离获得，主要用于与异丁烯经烃化制异辛烷，作为汽油辛烷值的改进剂，也可用作冷 …

2023年9月22日 · Butane is a straight-chain alkane hydrocarbon with the formula C4H10, commonly used as fuel in lighters and portable stoves. Isobutane, on the other hand, is a branched isomer of butane, often utilized as a refrigerant and a propellant in aerosol sprays.

Isobutane is a hydrocarbon and one of two isomers of butane. Butanes are highly flammable, colorless, odorless, easily liquefied gases. They are components of gasoline and can also be used as refrigerants and propellants in aerosol sprays. Butane gas is sold bottled as a fuel for cooking and camping and is also found in cigarette lighters.

n-Butane and isobutane are isomers of butane, meaning they share the same molecular formula (C4H10) but differ in their structural arrangement. This difference in structure leads to slightly different physical properties, including boiling points.

The main differences between butane and isobutane are: Structure: Butane has its four carbon atoms bonded in a continuous chain, while isobutane has a branched structure. Boiling Point: Butane has a sea level boiling point of -0.5°C, while isobutane has a boiling point of -12°C.
