Dissolved Acetylene is the chemical compound with the formula HC2H. It is a hydrocarbon & the simplest alkynes.
The colorless gas is widely used as a fuel & a chemical building block. It is unstable in pure form & thus is usually handled as a solution.
It is highly flammable gas & is used for welding & cutting due to it's high flame temperature & heat distribution.
It is the only fuel gas that creates a flame hot enough to cut & weld steel. Acetylene’s high level of reactivity makes it a very useful fuel gas for welding, heat treatment, carbon coating, fabrication & glass moulds
