Introduction
2-n-n-pentylfuran is an organic compound. The following is an introduction to some of the properties, uses, preparation methods and safety information of 2-n-n-pentylfuran:
Quality:
- Appearance: Colorless liquid
- Solubility: soluble in alcohol and ether, insoluble in water
- Chemical properties: Sensitive to oxidants and strong acids, prone to polymerization reactions
Use:
- 2-n-n-pentylfuran is often used as an intermediate in organic synthesis and materials science
- Because of its obvious adsorption properties, it is widely used in dye and dye wastewater treatment
Method:
2-n-n-pentylfuran can be prepared by:
- 2-n-n-pentylfuran was obtained by direct reaction of alkynypropylberyllium and n-pentylene reaction, and then reduced reaction to obtain 2-n-n-pentylfuran.
- 2-ammonium sulfate 5-hydroxypentanone is generated by the reaction of 2-pentenone and ammonium sulfate, and then 2-n-pentylfuran is obtained by heating and dehydration.
Safety Information:
- 2-N-n-pentylfuran has the properties of irritation and eye damage, so avoid contact with skin and eyes when using it.
- Good ventilation measures should be taken during use to avoid inhaling gases.
- It should be stored in a cool, dry, well-ventilated place, away from fire and oxidants.
