NEW MATERIAL:A fluorine-containing ketal and acetal of formulaI[Rf is fluorine-containing aliphatic group; R1 and R2 are H, aliphatic group and aromatic group; R1 and R2 together may form a ring when they are aliphatic group; X and Y are H or 1W3C alkyl; (n) is an integer 0W6].
EXAMPLE: The compound of formula II.
USE: Useful as a surface tension reducing agent for organic solvent coating materials or leveling agents of waxes, and capable of improving the wetting property for the untreated surface by reducing the surface tension of the organic solvent and imparting improved effects to various organic solvent treating agents, etc.
PROCESS: A fluorine-containing epoxide of formula III is reacted with a carbonyl group-containing compound of formula IV in the presence of a catalyst at about 20W150°C to afford the compound of formulaI. The raw material compound of formula IV is preferably used in a small excess.
