Abstract
Abstract A PROCESS IS DESCRIBED FOR PREPARING ALCOHOLS, ALDEHYDES, AND MIXTURES THEREOF, BY REACTING OLEFINS, CARBON MONOXIDE AND WATER USING METALLIC RHODIUM AS THE CATALYST. THE REACTION IS CARRIED OUT AT ELEVATED TEMPERATURES (TO ABOUT 300* C.) AND UNDER PRESSURES ABOVE ATMOSPHERIC (TO 20,000 P.S.I.). THE ALCOHOLS AND/OR ALDEHYDE PRODUCED CONTAIN ONE CARBON ATOM MORE THAN THE STARTING OLEFIN; THEY ARE ESPECIALLY USEFUL AS SOLVENTS AND INTERMEDIATES FOR THE PREPARATION OF CARBOXYLIC ACIDS FOR EXAMPLE.
