摘要： A process for the recovery of a weak organic acid, such as a low molecular weight alcohol, from an aqueous solution containing not more than 40% by volume of the organic acid, comprises dissolving a base or a basic salt of an acid having a pK a of greater than 6 in th aqueous solution in an amount of at least 26 g/100 ml of solution, the base or basic salt being substantially more soluble in water than in the weak organic acid, to form a two phase system comprising a lower phase rich in the base or basic salt and an upper phase rich in the weak organic acid, and recovering the weak organic acid from the upper phase.
