Phenylacetylene Usage And Synthesis
Chemical Properties    colourless liquid
Uses    Ethynylbenzene, an aromatic hydrocarbon, is important in the petrochemical industry as an intermediate in the production of styrene, which in turn is used for making polystyrene, a common plastic mate rial.
Purification Methods    Distil phenylacetylene through a spinning band column. It should be filtered through a short column of alumina before use [Collman et al.
