Abstract
Official abstract text for this publication.
A continuous process is provided for selective formation of a vinyl ester by reactive distillation from a corresponding carboxylic acid. Carboxylic acid, vinyl acetate, and a palladium acetate—bidentate ligand catalyst complex are provided and reacted in a typical embodiment. Acetic acid and vinyl acetate are continuously removed from the reaction mixture and vinyl acetate is recycled to the reaction mixture. The vinyl ester product is separated from the vinyl acetate, residual carboxylic acid, residual acetic acid, and catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A continuous process for selective formation of a vinyl ester from its corresponding carboxylic acid, the process comprising: (a) providing a carboxylic acid, vinyl acetate, and a homogeneous transvinylation catalyst comprising palladium to a reaction mixture; (b) reacting the carboxylic acid and vinyl acetate in the presence of the homogeneous transvinylation catalyst comprising palladium in the reaction mixture to form a vinyl ester product and acetic ac…
