Process for workup of a crude ester comprising esterification catalyst hydrolysis product in suspended particulate form

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 suspoe...

Zusammenfassung: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. 在后处理包含呈悬浮颗粒形式的酯化催化剂水解产物的粗酯的方法中,a)在乳化槽中将粗酯与1-10重量%的水混合,且使水乳化于粗酯中以获得悬乳液,b)将来自乳化槽的悬乳液转移至含有水不饱和粗酯初始装料的附聚槽中,从而在悬乳液与粗酯初始装料的混合物中建立低于水在粗酯中的溶解度极限的水含量,因此悬浮颗粒状酯化催化剂水解产物形成稳定附聚物,和c)滤出所形成的附聚物。
