Patent number: 5710316Abstract: A transesterification process for making allyl esters of aromatic carboxylic acids from the corresponding alkyl esters and allylic alcohols is disclosed. The alkyl ester/allylic alcohol mixture is dried by distillation to less than about 200 ppm water before heating it in the presence of the transesterification catalyst. The resulting allyl ester is obtained rapidly in high yield with a minimal level of catalyst. In addition, product isolation is simple, and color is exceptionally low. The process is particularly valuable for making diallyl phthalate from dialkyl esters of phthalic acid.Type: GrantFiled: November 27, 1996Date of Patent: January 20, 1998Assignee: Arco Chemical Technology, L.P.Inventors: Jude T. Ruszkay, Katherine A. McCarron

Patent number: 5430179Abstract: The present invention relates to a homogeneous, ruthenium catalyzed liquid phase process for vinyl ester synthesis. It has been found that by adding at least one selectivity enhancer to the reaction system, selectivity to the addition reaction is improved while byproduct formation is inhibited. Useful selectivity enhancers include non-reacting heteroatom containing molecules that are believed to act by weakly coordinating to the ruthenium/phosphine ligand complex.Type: GrantFiled: July 28, 1994Date of Patent: July 4, 1995Assignee: Union Carbide Chemicals & Plastics TechnologyInventors: David M.
