Abstract:
The invention relates to a method for producing carboxylic acid esters by reacting carboxylic acids and/or carboxylic acid anhydrides with at least one alcohol having at least 5 carbon atoms, selected from alkanols and cycloalkanols, in the presence of an ionic liquid and an acidic esterification catalyst. The invention also relates to the use of the thus obtained carboxylic acid esters as a plasticizer or in a plasticizer composition for thermoplastic polymers and elastomers.
