Dichloromethane water azeotrope
WebThe solubility of dichloromethane in water (as well as the solubility of water in dichloromethane) depends on temperature.At a temperature of T = 20 ∘ C, the solubility amounts to 17.6 g dichloromethane per 1 kg water; i.e. the mass fraction of dichloromethane is w C A 2 H A 2 Cl A 2 = 0.0173 or w C A 2 H A 2 Cl A 2 = 1.73 % . … WebNov 30, 2024 · Salting out is a technique that takes advantage of one solvent's reduced solubility in a solution of some compound relative to its solubility in pure water. This is mostly used for polar solvents that are miscible or highly soluble in water, especially when normal distillation produces an azeotrope.This technique is often used prior to distilling …
