Abstract
Oxygenated hydrocarbon compounds containing from one to four carbon atoms, e.g. acids, alcohols and/or aldehydes are produced by reacting carbon monoxide with hydrogen in the presence of a supported mixture of a rhodium component and a chromium component, optionally incorporating also iron, manganese, molybdenum, tungsten or ruthenium at elevated temperature and generally at elevated pressure. A preferred support is silica which may be activated by the addition of metal and non-metal activators followed by calcination, prior to incorporation of the rhodium and chromium components.
