Phenylacetylene

Phenylacetylene is an alkyne hydrocarbon containing a phenyl group. It exists as a colorless, viscous liquid. In research, it is sometimes used as an analog for acetylene; being a liquid, it is easier to handle than acetylene gas. Phenylacetylene is an alkyne hydrocarbon containing a phenyl group.

In the laboratory, phenylacetylene can be prepared by elimination of hydrogen bromide from styrene dibromide using sodium amide in ammonia: It can also be prepared by the elimination of hydrogen bromide from bromostyrene using molten potassium hydroxide.
