Diethyl ether freezing point

Diethyl ether is a common laboratory aprotic solvent. It has limited solubility in water (6.05 g/100 ml at 25 °C [2]) and dissolves 1.5 g/100 g (1.0 g/100 ml) water at 25 °C. [12] This, coupled with its high volatility, makes it ideal for use as the non-polar solvent in liquid-liquid extraction. See more Diethyl ether, or simply ether, is an organic compound in the ether class with the formula (CH3CH2)2O or (C2H5)2O, sometimes abbreviated as Et2O, where Et stands for monovalent ethyl group CH3CH2 which is often … See more It is particularly important as a solvent in the production of cellulose plastics such as cellulose acetate.
