  • Process for making formic acid utilizing lower-boiling formate esters
    Patent number: 10570081
    Abstract: Disclosed is a process for recovering formic acid from a formate ester of a C3 to C4 alcohol. Disclosed is also a process for producing formic acid by carbonylating a C3 to C4 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.
    Type: Grant
    Filed: July 24, 2018
    Date of Patent: February 25, 2020
    Assignee: Eastman Chemical Company
    Inventors: Scott Donald Barnicki, Robert Thomas Hembre, Sumit Chakraborty, Gerald Wayne Ollis, Randy Lynn Jennings, Stijn Van de Vyver
  • Process for making formic acid utilizing higher-boiling formate esters
    Patent number: 10544077
    Abstract: 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.
