| titleOfInvention | Catalytic method for producing aliphatic straight chain and beta-alkyl branched carboxylic acids |
| abstract | The present invention relates to a catalytic process for the preparation of aliphatic straight-chain and β-alkyl-branched carboxylic acids having 5 to 13 carbon atoms by catalytic oxidation of the corresponding aldehydes with oxygen or oxygen-containing gas mixtures in the liquid phase. The catalyst system contains both alkali metal or alkaline earth metal carboxylates or a mixture thereof in an amount, calculated as alkali metal or alkaline earth metal, of in each case 2.5 mmol to 25 mmol per mole of aldehyde used, and at the same time metals selected from the group of titanium, vanadium, Chromium, molybdenum, iron, cobalt, nickel, ruthenium, rhodium, palladium, copper and zinc in amounts of not more than 25 ppm, based on the aldehyde used, or compounds of such metals, wherein the catalyst system is the reaction product of an aldehyde oxidation reaction and the catalyst system in a such amount is used for the oxidation of the aldehydes, that the oxidation of the aldehydes in the presence of alkali or alkaline earth metal carboxylates or a mixture thereof in an amount calculated as the alkali or alkaline earth metal, each from 0.5 mmol to 5 mmol per mole of used Aldehyde, and from 0.05 to 5.0 ppm of a metal selected from the group of tit on, vanadium, chromium, molybdenum, iron, cobalt, nickel, ruthenium, rhodium, palladium, copper and zinc or the appropriate amount of a compound of such a metal or a mixture of such metals and / or metal compounds, based on the aldehyde used. |
