General description
Diethyl ether (DEE) is a highly volatile organic compound (VOC), commonly used as a solvent in laboratories. In organic synthesis, DEE is employed as a reaction solvent for Grignard reactions and other reactions, including organometallic reagents. It also finds application as an extraction solvent in chemical synthesis.
Application
Diethyl ether can be used as:
- An additive in biodiesel and diesel blends to improve the performance of diesel engines.
- A chromatography solvent for extraction and purification of organic compounds.
- A solvent for recrystallization of organic compounds.
