Formula of Ethyne

Preparation of Acetylene (Ethyne)

• Different preparative techniques can generate acetylene and is sometimes produced as a secondary result.
• In the past, it was a by-product of ethylene production via hydrocarbon cracking.
• The methods for producing acetylene include partial combustion of methane, refining during ethylene production, and hydrolysis of chemical carbide.
• It can also be created through the dehydrohalogenation of alkyl dihalides or vicinal dihalides.
