Process according to claim 1 ,wherein the acetic acid is added in an amount in the range from 6 mol to 7 mol of acetic acid per mole of diisobutene.4. Process according to claim 1 ,wherein the reaction mixture is heated to a temperature in the range from 80° C. to 160° C. in process step f).5. Process according to claim 1 ,wherein the CO is fed in in process step e) such that the reaction proceeds under a CO pressure in the range from 10 bar to 40 bar.6. Process according to claim 1 ,wherein the process comprises the additional process step g):g) addition of sulfuric acid. The invention relates to a process for Pd-catalyzed hydroxycarbonylation of diisobutene:acetic acid/diisobutene ratio.Carboxylic acids including propionic acid, adipic acid and fatty acids are used in the preparation of polymers, pharmaceuticals, solvents and food additives. The routes leading to carboxylic acids generally include the oxidation of hydrocarbons, alcohols or aldehydes, the oxidative cleavage of olefins by ozonolysis, the hydrolysis of triglycerides, nitriles, esters or amides, the carboxylation of Grignard or organolithium reagents, and the halogenation and subsequent hydrolysis of methyl ketones in the haloform reaction.The hydrocarboxylation of olefins is a highly promising and environmentally-friendly method for obtaining carboxylic acids. Acetic acid is produced by carbonylation of methanol, which is carried out with iodide. In the Koch reaction, the addition of water and carbon monoxide to alkenes is catalyzed by strong bases. This method is effective with alkenes that form secondary and tertiary carbocations, e.g. isobutylene to pivalic acid. The hydrocarboxylation occurring with the ...

The invention relates to a process for Pd-catalyzed hydroxycarbonylation of diisobutene: ligand/Pd ratio.Carboxylic acids including propionic acid, adipic acid and fatty acids are used in the preparation of polymers, pharmaceuticals, solvents and food additives. The routes leading to carboxylic acids generally include the oxidation of hydrocarbons, alcohols or aldehydes, the oxidative cleavage of olefins by ozonolysis, the hydrolysis of triglycerides, nitriles, esters or amides, the carboxylation of Grignard or organolithium reagents, and the halogenation and subsequent hydrolysis of methyl ketones in the haloform reaction.The hydrocarboxylation of olefins is a highly promising and environmentally-friendly method for obtaining carboxylic acids. Acetic acid is produced by carbonylation of methanol, which is carried out with iodide. In the Koch reaction, the addition of water and carbon monoxide to alkenes is catalyzed by strong bases. This method is effective with alkenes that form secondary and tertiary carbocations, e.g. isobutylene to pivalic acid. The hydrocarboxylation occurring with the simultaneous addition of CO and HO to ...

The iridium catalyst used comprises a phosphorus-containing ligand with the ratio iridium: ligand in the range of 1: 1, to 1: 100. With high catalyst activities and reduced amount of catalyst very high conversion frequencies are obtained.
