In a process for workup of a crude ester comprising esterification catalyst hydrolysis product in suspended particulate form, a) the crude ester is admixed in an emulsifying tank with 1% to 10% by weight of water and the water is emulsified in the crude ester to obtain a suspoemulsion, b) the suspoemulsion from the emulsifying tank is transferred to an agglomerating tank containing an initial charge of water-undersaturated crude ester, such that a water content below the solubility limit of water in the crude ester is established in the mixture of the suspoemulsion and the initial charge of crude ester, as a result of which the suspended particulate esterification catalyst hydrolysis products form stable agglomerates, and c) the agglomerates formed are filtered off.
