  • Patent number: 11851392
    Abstract: An efficient process useful for the self-condensation of aliphatic aldehydes is provided, catalyzed by dialkylammonium carboxylate salts. In particular, the invention provides a facile method for the preparation of 2-ethyl hexenal via the self-condensation of butyraldehyde using various dialkylammonium carboxylates, e.g., diisopropylammonium acetate or dimethylammonium acetate, as catalyst. Additionally, residual nitrogen arising from the catalyst can be reduced to ?100 ppm levels in the product via a simple washing procedure. The invention provides a process for preparing alkenals under conditions which limit the formation of undesired impurities and high-boiling oligomeric substances.

  • 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.

  • 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.

  • Patent number: 10435349
    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.
