Independent Claim
137 words
A PROCESS FOR PREPARING ORGANIC CARBOXYLIC ACIDS WHICH CONSISTS ESSENTIALLY OF CONTACTING IN A REACTION ZONE ONE MOLE OF A C2 TO C18 MONOOLEFINS WHICH CONTAINS ITS DOUBLE BOND IN ALPHA POSITION WITH ABOUT 1 TO 4 MOLES OF WATER UNDER 1000 TO 5000 P.S.I.A. PRESSURE EXERTED BY A MIXTURE OF CARBON MONOXIDE AND HYDROGEN SUPPLIED TO SAID REACTION ZONE IN A RATIO OF FROM ABOUT 10 TO 30 MOLES OF CARBON MONOXIDE PER MOLE OF HYDROGEN IN THE PRESENCE OF 0.2 TO 10 MOL. PERCENT BASED ON THE MONOOLEFIN OF A COBALT-CONTAINING CARBONYLATION CATALYST, MAINTAINING THE TENPERATURE IN THE REACTION ZONE BETWEEN ABOUT 100 AND 200*C. FOR FROM A FEW MINUTES TO ABOUT 10 HOURS AND RECOVERING AN ORGANIC CARBOXYLIC ACID FROM THE REACTION MIXTURE HAVING ONE MORE CARBON ATOM PER MOLECULE THAN THE FEED OLEFIN.
