Acetylene (C2H2) properties

Acetylene ( C2H2 ) – Also known as etin – from the group of alkynes is a compound. This gas is often used in the chemical industry as a base material in the synthesis of organic compounds (such as acrylate or chloroethylene). Acetylene is also used during hydrocarbon cracking (oil refining) and when welding at temperatures up to 3,000°C.

Health effects of acetylene

At ambient temperature, etine is colorless and theoretically odorless (when it is a pure gas). Even if this gas is not toxic, respiratory hazards to drown may cause . It is extremely flammable (R12) and poses risks of explosion (R5) with or without air contact (R6). It reacts with basically almost any oxidizer and can form toxic and/or corrosive gas mixtures even at low concentrations.
