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.

Abstract: Disclosed is a process for the purification of a mixed diol stream. The mixed diol stream comprising two-, three-, and four-carbon diols is separated into component diols by extraction with a hydrophobic solvent mixture. The diols recovered in the extractant may be removed from the extractant stream by back extraction with water or by distillation with an azeotrope-forming agent present, preferably an azeotroping agent already present in the extractant mixture.

Abstract: 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.

Abstract: Iron-based homogeneous catalysts, supported by pincer ligands, are employed in the catalytic dehydrocoupling of methanol to produce methyl formate and hydrogen. As both methanol and methyl formate are volatile materials, they can be readily separated from the catalyst by applying vacuum at room temperature. The hydrogen by-product of the reaction may be isolated and utilized as a feedstock in other chemical transformations.

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.
