Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
Catalytic process for the oxidative alkoxycarbonylation of olefins, in which one or more olefins, a primary or secondary alcohol, carbon monoxide, and oxygen are contacted and reacted in the presence of a palladium(II) compound and a heteropoly acid, said heteropoly acid having the formula [H].sub.8+a-n [XMo.sub.12-a-b W.sub.b V.sub.a O.sub.40 ] wherein: X is an element selected from the group consisting of P, Si, As, Ge, Ti and Zr; n is the oxidation state of X; a is 0 to about 4; b is 0 to about 12; at a temperature greater than about 40° C., wherein the process the amount of palladium is about 10 -5 to about 10 -8 gram-atom per mole of olefin and the amount of heteropoly acid is about 5×10 2 to about 1×10 5 moles per gram-atom of palladium.
