Abstract

Process for the preparation of sodium fluoroalcoholates. This process consists in performing the sodium treatment of the fluoroalcohols by means of sodium methylate and in trapping methanol by means of a molecular sieve. Sodium fluoroalcoholates can be employed directly for substitution reactions of polydichlorophosphazenes. [EP0335776A1]
