How is Et2O extracted from a reaction mixture?
The reaction mixture was extracted with Et2O (3A-50 mL), the combined organic layer was dried over anhydrous MgSO4 and concentrated in vacuo to afford yellowish oil (4.389 g). The reaction mixture was stirred at room temperature for 20 hours, quenched with saturated NH4Cl solution (20 mL) and extracted with Et2O (3A-30 mL).
What is the melting point of Et2O in water?
It has a melting point of – 116.2°C, a boiling point of 34.6°C, and a density of 0.713 g/cm3 at 20°C. Miscible in all proportions with alcohol and many other organic solvents, it is only 6.6-percent soluble in water at 20°C. It readily dissolves fats. Diethyl ether forms an azeotropic mixture with water;
