text: ABSTRACT Substantially anhydrous formic acid is recovered from aqueous solution by azeotropically distilling the solution with a non-aromatic hydrocarbon entrainer which boils between about 60 and 120 C. Paraffinic and alicyclic hydrocarbons boiling between about 80 C and about 115 C are particularly suitable entrainers.
text: It has now been discovered that substantially anhydrous formic acid can be recovered from an aqueous solution, which may also contain acetic acid, by azeotropically distilling the formic acid out of the aqueous solution with an entrainer which is immiscible with formic acid and with water and which has a boiling point between about 60 C and about C, particularly suitable entrainers being members of the group consisting of paraffinic and alicyclic hydrocarbons.
