Product Name:1,3-Pentadiene
English Name:1,3-Pentadiene
CAS No.:504-60-9
Aliases:Piperylene, 1-Methylbutadiene, Pentadiene
Molecular Formula:C₅H₈
Physical Properties:Colorless volatile liquid with a mild characteristic odor. Density: approximately 0.683 g/cm³ (20°C). Boiling point: approximately 42°C (trans-isomer) / 44°C (cis-isomer). Flash point: -28°C; ignition point: approximately 180°C. Insoluble in water; readily soluble in ethanol, diethyl ether, benzene, acetone and other organic solvents. The conjugated double bonds render the molecule highly reactive, readily undergoing addition, polymerization and oxidation reactions.
Uses:Primarily used as a raw material for C5 petroleum resins, which are widely applied in coatings, adhesives and rubber auxiliaries. Also serves as an organic synthesis intermediate for the production of cyclopentadiene, pentadiene rubber, curing agents and various fine chemicals.
Technical Specifications:
Purity: ≥99.0%
Appearance: colorless transparent liquid
Boiling range: 40~45°C (at atmospheric pressure)
Density (20°C): 0.680~0.690 g/cm³
Water content: ≤0.05%
