HSDB 1086 - Introduction
1-Pentene is a colorless liquid with an odor similar to petroleum ether. It is an unsaturated hydrocarbon containing a carbon-carbon double bond. The following are about the specific properties of 1-pentene:
1. Physical properties:
-Density: 0.66 g/ml
-Boiling point: 36 degrees Celsius
-Melting point:-131 degrees Celsius
-Solubility: Solubility with non-polar solvents such as alcohols, ethers, hydrocarbons and lipids.
2. chemical properties:
-It is easy to react with other compounds, such as reacting with chlorine to generate 1,2-dichloropentane.
-It can be oxidized to 1,5-pentanedione by oxidants such as hydrogen peroxide at high temperatures.
-Can be converted into other compounds through addition reactions.
3. Application:
-1-pentene is an important raw material in the organic synthesis industry and can be used to prepare other organic compounds, such as 1,5-pentadiene, 1-pentenol and 1,5-pentanediol.
-It can also be used as a solvent, food additives and flavors.
4. preparation method:
-1-pentene can be obtained by the dehydrogenation reaction of hydrocarbons, and the commonly used method is obtained by the dehydration and dehydrogenation reaction of butanol catalyzed by a hydrocarbon dehydrogenation catalyst.
5. Safety Information:
-1-pentene is a flammable liquid, easy to burn when exposed to open flame, high temperature or oxidant.
-Exposure to 1-pentene may cause skin and eye irritation.
-Pay attention to protective measures when using 1-pentene, such as wearing protective gloves and goggles to ensure a well-ventilated working environment.
