Document Type and Number:
Japanese Patent JP6034388
Kind Code:
B2
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.
