Description

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.

This Thermo Scientific brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific.
