Diethyl ether is a popular non-polar solvent in liquid-liquid extraction. As an extractant, it is immiscible with and less dense than water. Although immiscible, it has significant 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.
log 10 of Diethyl Ether vapor pressure. Uses formula: log e P m m H g = {\displaystyle \scriptstyle \log _{e}P_{mmHg}=} log e ( 760 101.325 ) − 12.4379 log e ( T + 273.15 ) − 6340.514 T + 273.15 + 95.14704 + 1.412918 × 10 − 05 ( T + 273.15 ) 2 {\displaystyle \scriptstyle \log _{e}({\frac {760}{101.325}})-12.4379\log _{e}(T+ ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. [8] Being polar and having a wide liquid range, THF is a versatile solvent. It is an isomer of another solvent, butanone.
The free base form of cocaine is prepared from cocaine hydrochloride by extracting the cocaine with an alkaline solution (sodium hydroxide or ammonia) and adding a non-polar solvent such as diethyl ether or benzene. The mixture separates into two layers, the top solvent layer containing the dissolved cocaine.

The following table shows that the intuitions from "non-polar", "polar aprotic" and "polar protic" are put numerically – the "polar" molecules have higher levels of δP and the protic solvents have higher levels of δH. Because numerical values are used, comparisons can be made rationally by comparing numbers.
