Abstract
Abstract This specification discloses an insoluble resin-metal compound complex, the method for its preparation, and its use in carrying out a catalyzed reaction. The complex is a weak base anion exchange resin which has been contacted with a solution of a coordination compound having at least two ligands connected to at least one central metal atom to bond chemically the resin to the metal atom by replacement of at least one of the ligands of the coordination compound by a functional group of the weak base anion exchange resin. The complex can be used as a catalyst for hydrogenation, carbon monoxide insertion, polymerization, isomerization, vinyl ester exchange, and ethylene oxidation reactions, among others.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
A process for manufacturing vinyl acetate which comprises reacting ethylene and oxygen in the presence of liquid acetic acid at a temperature up to 250° C. and in the presence of an insoluble resin-metal coordinative complex compound comprising an insoluble weak base exchange resin having amine, phosphine, arsine, stibine, thiol or sulfide Lewis base substituents, coordinatively, nonionically bonded through said substituents to a metal atom of palladium, said metal atom having chemically bonded thereto at least one ligand and said complex containing on a weight basis 0.01 to 50% of metal, 39 to 99% of resin with the sum of the amount of the ligand and metal not exceeding 61%.
Claim 2
Dependent Claim
110 words
A process for manufacturing vinyl acetate which comprises reacting ethylene and oxygen in the presence of liquid acetic acid at a temperature up to 250° C. and in the presence of an insoluble resin-metal coordinative complex compound comprising an insoluble weak base exchange resin having amine, phosphine, arsine, stibine, thiol or sulfide Lewis base substituents, coordinatively, nonionically bonded through said substituents to a metal atom of palladium, said metal atom having chemically bonded thereto at least one ligand and said complex containing on a weight basis 0.01 to 50% of metal, 39 to 99% of resin with the sum of the amount of the ligand and metal not exceeding 61%.
