Patent number: 10544077Abstract: 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.Type: GrantFiled: July 24, 2018Date of Patent: January 28, 2020Assignee: Eastman Chemical CompanyInventors: Scott Donald Barnicki, Robert Thomas Hembre, Sumit Chakraborty, Vickie Haygood Osborne, Michael Richard Laningham, Stijn Van de Vyver

Patent number: 10435349Abstract: A process for preparing a variety of secondary and tertiary alkyl formate esters via the coupling of methanol and secondary (or tertiary) alcohols. Iron-based catalysts, supported by pincer ligands, are employed to produce these formate esters in high yields and unprecedentedly high selectivities (>99%). Remarkably, the coupling strategy is also applicable to bulkier tertiary alcohols, which afford corresponding tertiary formate esters in moderately high yields and high selectivities.Type: GrantFiled: July 24, 2018Date of Patent: October 8, 2019Assignee: Eastman Chemical CompanyInventors: Sumit Chakraborty, Steven J. Adams, Robert Thomas Hembre, Scott Donald Barnicki, Michael Richard Laningham, Gerarld Wayne Ollis, Randy Lynn Jennings
