Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
140 words
IN A PROCESS FOR THE CONVERSION OF AN OLEFINIC HYDROCARBON TO A CARBONYL COMPOUND SELECTD FROM THE GROUP CONSISTING OF ALDEHYDES AND KETONES BY OXIDATION OF AN OLEFINIC CARBON ATOM OF SAID OLEFINIC HYDROCARBON TO A CARBONYL GROUP BY CONTACTING SAID HYDROCARBON AND OXYGEN WITH AN ACID TO NEUTRAL AQUEOUS CATALYST SOLUTION OF A SALT OF A NOBLE METAL SELECTED FROMTHE GROUP CONSISTING OF PALLADIUM, IRIDIUM, RUTHENIUM, RHODIUM, AND PLATINUM, AND AS A REDOX SYSTEM, A SALT OF THE METAL SHOWING SEVERAL VALENCE STATES UNDER THE REACTION CONDITIONS APPLIED, THE IMPROVEMENT OF CONTACTING AN ALPHA OLEFIN HAVING AT LEAST 3 CARBON ATOMS WITH A CATALYST SOLUTION IN WHICH THE CONCENTRATION OF SAID SALT OF A NOBLE METAL IS GREATER THAN 0.25 MOL PER LITER OF CATALYST SOLUTION, WHEREBY THE PROPORTION OF ALDEHYDES TO KETONES IN THE REACTION PRODUCT IS INCREASED.
