1-PENTYNE Chemical Properties,Uses,Production

Chemical Properties

Clear colorless to pale yellow liquid

Uses

1-Pentyne has been used in preparation of:

lithium acetylides, required for asymmetric synthesis of α,α-dibranched propargyl sulfinamides
7-hydroxy-10-methoxy-3H-naphtho[2.1-b]pyrans

Uses

1-Pentyne has been used in preparation of:lithium acetylides, required for asymmetric synthesis of α,α-dibranched propargyl sulfinamides. It is also used to synthesize 7-hydroxy-10-methoxy-3H-naphtho[2.1-b]pyrans.

General Description

Selective and non-selective hydrogenation of 1-pentyne catalyzed by silica-supported palladium has been studied by in situ X-ray absorption spectroscopy.

Safety Profile

Dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also ACETYLENE COMPOUNDS
