Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
THE OXIDATIVE CARBONYLATION OF HYDROCARBON OLEFINS HAVING FROM 2 TO ABOUT 25 CARBONS THAT COMPRISES CONTACTING SAID OLEFIN, OXYGEN AND CARBON MONOXIDE WITH AN ORGANIC REACTION SOLVENT AT A TEMPERATURE OF 30* TO ABOUT 300*C. AND A PRESSURE SUFFICIENT TO MAINTAIN THE SOLVENT IN LIQUID PHASE, SAID SOLVENT CONTAINING FROM ABOUT 0.01 TO ABOUT 5.0 WEIGHT PERCENT OF A CATALYST COMPRISING A PLATINUM GROUP METAL AND 0.1 TO ABOUT 50 WEIGHT PERCENT OF A DEHYDRATED MOLECULAR SIEVE COMPRISING A CRYSTALLINE ALUMINOSILICATE HAVING A UNIFORM PORE DIAMETER WHICH IS NONREACTIVE WITH THE ORGANIC REACTANTS AND PRODUCTS AND THE CATALYST AND INSOLUBLE IN THE REACTION MEDIUM AT THE REACTION CONDITIONS TO THEREBY OBTAIN AN ALPHA,BETAETHYLENICALLY UNSATURATED ACID HAVING A TOTAL OF ONE MORE CARBON THAN SAID OLEFIN.
