Abstract:
A process for manufacturing a polyfluroalkanoyl phosphorodichloridate comprising reacting a polyfluoroalkanol having the general formula Rf—CH2—OH, wherein Rf is a linear or branched C1-C8 perfluoroalkyl group optionally interrupted by O, with at least 4 moles of POCl3 per mole of Rf—CH2—OH in the presence of 0.1 to 0.2 moles of LiCl catalyst per mole of Rf—CH2—OH at a temperature between 95° C. and 110° C. to form a phosphorodichloridate of the general formula Rf—CH2—O—P(O)Cl2.
