PROCESS FOR THE PREPARATION OF FLUORINATED ACRYLIC ACIDS AND DERIVATIVES THEREOF

摘要

In the preparation processes known hitherto for haloacrylic acids and deuterated derivatives thereof, it is necessary to use chemicals, some of which are very toxic or very expensive. However, fluoroacrylic acids are successively prepared from halogenated fluoropropionic acids and derivatives thereof by electrochemical elimination of halogen atoms. For this purpose, the acids or derivatives thereof are electrolyzed in a water-containing solution at a temperature from -10 DEG C. to the boiling point of the electrolysis liquid.
