乙炔

乙炔,俗称风煤电石气电土,是炔烃化合物系列中体积最小的一员,主要作工业用途,特别是烧焊金属方面。

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:

乙炔在室温下是无色、极易燃的气体。纯乙炔是无臭的,但工业用乙炔由于含有硫化氢、磷化氢等杂质,而有一股大蒜的气味。乙炔的化学能主要贮存于它的三键中。

在摄氏400度以上, 乙炔会聚合生成乙烯基乙炔(C4H4)和苯(C6H6)。在摄氏900度以上则会形成炭黑。

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:

Acetylene 乙炔

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. 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. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.
