Production of alkoxylated compounds useful as nonionic surfactants comprises filtration using a cellulose filter aid in the presence of water

摘要

Production of alkoxylated compounds by reacting active hydrogen compounds or carboxylate esters with alkylene oxides in the presence of a heterogeneous catalyst, comprises adjusting the water content of the reaction mixture to at least 1.5 wt.% and filtering the reaction mixture using a cellulose filter aid.
