개요
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 undergoes polymerization catalyzed by Rh and Pt complexes to form polyphenylacetylene.
화학적 성질
colourless liquid용도
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.주요 응용
Terminal acetylene used in the conversion of nitrones to alkynyl hydroxyl amines in the presence of trimethylaluminum.Phenylacetylene was used in a study to investigate the mechanism of product formation during the palladium-catalysed phenylacetylene oxidative carbonylation reaction.
일반 설명
Phenylacetylene undergoes polymerization catalyzed by Rh and Pt complexes to form polyphenylacetylene.Purification Methods
Distil phenylacetylene through a spinning band column. It should be filtered through a short column of alumina before use [Collman et al. J Am Chem Soc 108 2988 1986; for pK see Brandsma Preparative Acetylenic Chemistry, 1st Edn Elsevier 1971, p. 15, ISBN 0444409475]. [Beilstein 5 IV 1525.]주의 사항
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.에티일벤젠 준비 용품 및 원자재
