Abstract
In a method for preparing formic acid, methyl formate is prepared with methanol as a reactant. In the method, methyl formate obtained from methanol in a reaction is fed through an ion exchange bed, in which the hydrolysis into formic acid and methanol and the separation of formic acid from methanol take place simultaneously by means of the catalytic and adsorbent properties of a solid in exchange material in the ion exchange bed
