Abstract: Alkali metal ions are separated off from alkoxylates containing alkali metal ions by a process comprising:a) dilution of the alkali metal-containing alkoxylate with an inert solvent,b) treatment of the alkali metal-containing solution of the alkoxylate with a cationic exchanger in order to obtain a substantially alkali metal-free solution of the alkoxylate, andc) removal of the solvent from the substantially alkali metal-free solution of the alkoxylate in order to obtain a substantially alkali metal-free and substantially solvent-free alkoxylate.

Abstract: The production of acrylic acid (I) and/or its esters comprises; (a) catalytic gas-phase oxidation of propene and/or acrolein to give a gaseous product containing (I), (b) absorption of the reaction product with a solvent, (c) distillation in a column to give crude (I) and solvent, (d) purification of (I) by crystallisation and optionally (e) esterification of crystallised (I). Also claimed is an apparatus for the process, comprising reactor(s) for stage (a), an absorption column, a distillation column, dynamic crystalliser(s) and static crystalliser(s), and container(s) for intermediate storage.

Abstract: A process for the continuous production of 1,3-dioxolan-2-ones such as ethylene carbonate or propylene carbonate by reacting a corresponding oxirane with carbon dioxide in the liquid phase in the presence of a catalyst comprises conducting the reaction in a two-part reactor in whose first part the reaction is taken with backmixing to a conversion of not less than 80% of the oxirane II and in whose second part the reaction is completed under nonbackmixing conditions, and passing the carbon dioxide in countercurrent to the oxirane II in the entire reactor.
