乙炔(acetylene),化学式为HC≡CH或C2H2,俗称电石气或风煤(“风”指压缩氧气,“煤”指乙炔),是最简单的炔烃,纯乙炔在常温常压下是无色无味的气体,但工业乙炔因含有硫化氢和磷化氢而具有刺激性(臭)气味。
Acetylene - Wikipedia
Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure HC≡CH. It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. [9]

Ethylene - Wikipedia
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C2H4 or H2C=CH2. It is a colourless, flammable gas with a faint "sweet and musky " odour when pure. [7] . It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

乙炔于1836年由英国科学家艾德蒙·戴维(Edmund Davy)发现,化学式为C2H2,有一个如下图所示的直线型结构: H - C ≡ C - H. 碳酸钙(石灰岩)和煤炭是生产乙炔的主要原料。 首先,碳酸钙会转化为氧化钙,煤炭则转化为焦炭。 然后氧化钙和焦炭会发生反应形成碳化钙和一氧化碳: CaO + 3C → CaC2 + CO 碳化钙加水会形成乙炔和氢氧化钙:CaC2 +2H2O → C2H2↑ + Ca (OH)2. 乙炔主要是用作制造其他化学品的,也被用于乙炔焊接。 在氧气中燃烧乙炔可以形成摄 …
Ethyne (Acetylene) - Structure, Properties, and Uses of C2H2
Ethyne, also known as acetylene, is an organic chemical compound with the chemical formula C 2 H 2. Since the entire chemical composition only features hydrogen and carbon atoms, this compound is a hydrocarbon. Ethyne is regarded by many to be the simplest alkyne since it consists of only two carbon atoms, which are triply bonded to each other.
