Process for the preparation of an ester, based at least on a. at least one alcohol component, b. at least one carboxylic acid component, c. optionally further additives, d. at least two different catalysts, and e. Max. 20% by weight of a solvent as process components, comprising in a reactor the process steps: i. Providing the process components, ii. Reacting the process components to obtain an ester A, iii. optionally after-treatment of the ester A, wherein in each case at least one of the at least two different catalysts is an electron donor and another catalyst of the at least two different catalysts is a sulfur-containing proton donor. |
