Abstract
The invention relates to a method for separating formic acid from a reaction mixture which comprises, in addition to formic acid, a polyoxometalate ion of general formula [PMoVO], where 6≤x≤11, 1≤y≤6, x+y=12 and 3<n<10, where n, x and y are each integers, wherein the separation occurs by means of an extraction using a linear primary alcohol, wherein the carbon chain of the alcohol comprises 5 to 12 carbon atoms, and the reaction mixture is present in a protic solvent.
