Chemical Properties

clear colorless to slightly yellow liquid

Uses

2-Pentyne was used to test the catalytic activity of nanoparticles of palladium supported on bacterial biomass, bio-Pd.

Safety Profile

A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Solutions with silver perchlorate explode on contact with mercury. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

It is stood with, then distilled at low pressure from sodium or NaBH4. [Beilstein 1 III 958, 1 IV 992.]
