Abstract:
Disclosed is a process for recovering formic acid from a formate ester of a C 3  to C 4  alcohol. Disclosed is also a process for producing formic acid by carbonylating a C 3  to C 4  alcohol, hydrolyzing the formate ester of the alcohol, and recovering a formic acid product. The alcohol may be dried and returned to the reactor. The process enables a more energy efficient production of formic acid than the carbonylation of methanol to produce methyl formate.

Claim (Index 17):
The process of  claim 14 , wherein the alcohol recovery zone comprises a process selected from the group consisting of\n c1) azeotropic distillation wherein; when the alcohol is a C 3  alcohol, the azeotroping agent comprises the formate ester of the alcohol and/or an ether of the alcohol; and when the alcohol is a C 4  alcohol, the azeotroping agent comprises the formate ester of the alcohol, the ether of the alcohol, and/or the alcohol; c2) azeotropic distillation using an azeotrope agent comprising C 5 -C 6  hydrocarbons, C 1 -C 3  chlorinated hydrocarbons, and/or C 4 -C 8  ethers; and c3) extractive distillation using an extractant comprising C 2 -C 4  glycols and/or C 4 -C 6  glycol ethers.
