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 9):
The process of  claim 8 , wherein the distillation zone further comprises a second distillation column and wherein the process further comprises\n b2) feeding the first bottoms to the second distillation column and removing the formic acid product as a second distillate and a second bottoms comprising formic acid in an amount within 5 weight percentage points of an amount of formic acid in a formic acid/water azeotrope at an operating pressure of the second distillation column; and b3) feeding the second bottoms to the first distillation column.
