第六章 炔烃和共轭二烯 Alkynes and Conjugated Dienes
Alkynes, also called acetylenes, are o hydrocarbons that contain a carbon carbon triple bond. acetylene itself, the simplest alkyne, was once widely used in industry as the starting material for the preparation of acetaldehyde, acetic acid, vinyl chloride, and other high- volume chemicals, but more efficient route using ethylene as starting material are now more common
