Applications
Phenylacetylene is involved in the preparation of styrene by reduction using Lindlar catalyst. It is used to study the mechanism of the palladium-catalyzed phenyl acetylene oxidative carbonylation reaction. It is also used in the polymerization process to prepare polyphenylacetylene namely 1,2,4-triphenylbenzene and 1,3,5-triphenylbenzene.

Solubility
Immiscible with water.

Notes
Store in cool place. Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with acids, halogens, alkali metals and oxidizing agents.
