Ester mixtures comprising the esters A(COOR1)(COOR1)x, A(COOR1)(COOR2)x, A(COOR2)(COOR1)x and A(COOR2)(COOR2)x, can be produced in a targeted way by processes in which acids A(COOH)x+1 or derivatives thereof are reacted with an amount (m1+s1) of R1OH and an amount m2 of R2OH, the reaction mixture being heated at boiling, the alcohol R1OH having a lower boiling point than the alcohol R2OH, A being an aromatic, alicyclic or aliphatic radical, x being 1 or 2, and R1 and R2 independently of one another being substituted or unsubstituted aryl radicals or linear or branched, substituted or unsubstituted alkyl radicals having 3 to 20 carbon atoms, m1 and m2 corresponding to the mole equivalents of the alcohol radicals OR1 and OR2 to be introduced into A(COOH)x+1 or derivatives thereof, and s1 being greater than 0.
