Claim 1
Independent Claim
96 words
A PROCESS FOR THE PREPARATION OF OXYGENCONTAINING ORGANIC COMPOUNDS WHICH COMPRISES REACTING AN ORGANIC UNSATURATED COMPOUND CONTAINING OLEFINIC UNSATURATION SIMULTANEOUSLY WITH CARBON MONOXIDE AND HYDROGEN IN THE PRESENCE OF A CATLYTIC QUANTITY OF A CARBONYL OF A METAL HAVING AN ATOMIC NUMBER OF FROM 26 TO 28 INCLUSIVE, SAID METAL CARBONYL BEING INTIALLY INTRODUCED AS SUCH INTO THE REACTION MIXTURE, AT A TEMPERATURE OF ABOUT 75* TO 250*C. UNDER A PRESSURE WITHIN THE RANGE OF 50 TO 3000 ATMOSPHERES WHEREBY THERMAL DECOMPOSITION OF THE SAID METAL CARBONYL IS SUPPRESSED, AND AN OXYGEN-CONTAINING REACTION PRODUCT IS OBTAINED.
