Abstract (en)

[origin: DE19706876A1] The invention relates to a method for producing carboxylic acids or their esters from olefins and carbon monoxide in the presence of water or alcohols at temperatures of between 100 and 270 DEG C and pressure of between 30 and 100 bar. Said method is characterized in that as halogen-free catalyst system it uses a mixture of a) nickel or a nickel compound; b) at least one of the metals of a group including chromium, molybdenum, wolfram, rhenium, ruthenium, osmium, rhodium, iridium, palladium, platinum, silver and gold, or a compound of these metals; c) at least one non-metallic compound from the group of tertiary or quaternary nitrogen, phosphorus or arsenic compounds and nitrogen-containing heterocyclic compounds.
