Use
Allene is colorless with a sweet odor. It is a flammable gas and may cause fl ash fi re at room temperature. Allene is the simplest member of the 1,2-diene class of compounds of hydrocarbons of the aliphatic chemical family. It is a benzene and petroleum ether. Allenes are not as stable as conjugated dienes or isolated dienes. Allene is slightly more strained than the isomeric methylactylene. Allene is chiefl y used in organic synthesis. It is incompatible with metals and oxidizing materials, therefore it is important to avoid copper and silver and their alloys when used under high pressure or temperature.
