发明名称 Process for the removal of HF from HF containing organic carbonates
摘要 Mixtures comprising organic carbonates, such as carbonates not substituted by fluorine, but especially fluorosubstituted organic carbonates, which are depleted in HF can be obtained from respective mixtures with a higher HF content by a step of stripping such mixture with an inert gas. For example, a reaction mixture comprising fluoroethylene carbonate and HF can be treated in this way. The mixture comprising organic carbonate which is depleted in HF can be distilled to obtain highly purified organic carbonate.
