A process for producing a mixture comprising tertiary isononanoic acids proceeding from 2-ethylhexanol is characterized in that 2-ethylhexanol is (a) reacted at a temperature of 0° C. to 40° C. with a mixture of concentrated formic acid and a concentrated Brønsted acid, wherein 2 to 10 mol of formic acid are used per mole of 2-ethylhexanol and the concentrated Brønsted acid is used in an amount that corresponds to 6 to 90 mol of protons per mole of 2-ethylhexanol. The resulting reaction mixture from step (a) is subsequently (b) brought into contact with water, and the mixture comprising tertiary isononanoic acids formed according to step b) is removed.
