摘要:
Disclosed is a process for recovering formic acid from a formate ester that allows for recovery of a formic acid product comprising greater than 75 wt. % formic acid. Disclosed is also a process for producing formic acid by carbonylating a carrier alcohol, hydrolyzing the formate ester of the carrier alcohol, and recovering a formic acid product comprising greater than 70 wt. % formic acid. Discloses are carrier alcohols that enable more favorable hydrolysis equilibriums and/or distillation sequences.
