| titleOfInvention | Phosphorus-containing derivatives of polyfluorinated alcohols and processes for obtaining the same |
| abstract | 1380907 Phosphorylated derivatives of polyfluorinated alcohols UGINE KUHLMANN 9 Dec 1971 [9 Dec 1970] 57318/71 Heading C2P The invention comprises a product having the general formula and the two isomeric forms of the formulµ in which C n F 2n+1 is a perfluorinated carbon chain, n is an integer between 2 and 18 (both inclusive) and X, Y and Z are the same or different and are halogen, OH, OMe (where Me is a metal equivalent) or an alkoxy, chloroalkoxy, aryloxy, a hydroxy polyalkyleneoxy group, optionally containing a chlorine atom, or the radical -N.ZZ<SP>1</SP>, Z and Z<SP>1</SP> being the same or different and being either H or an alkyl, cycloalkyl or aryl radical or Z and Z<SP>1</SP> are radicals which together with the N atom form a heterocyclic ring which may optionally contain oxygen as an additional hetero atom. They may be obtained by first preparing the corresponding dichlorophosphate product by either (a) reacting C n F 2n+1 -CH=CH 2 with PCl 3 and oxygen or an oxygen-containing gas, the molar ratio of PCl 3 to the olefin being preferably from 1 to 5, (b) by reacting a fluorinated epoxide of the formula with an excess of POCl 3 in the presence of a catalyst such as TiCl 4 , ZrCl 4 , stannic chloride or aluminium chloride, or (c) by treating a chlorohydrin: with an excess of POCl 3 , optionally in the presence of a tertiary amine. The dichlorophosphate products may then be reacted with water to form the free acids (X=Y=OH); with an alcohol or phenol, optionally in the presence of a tertiary amine; with an alkali metal alcoholate or phenate to form the corresponding esters, or with at least 4 molecular equivalents of a dialkylamine to form the corresponding phosphorodiamidate. The products are useful as emulsifiers, wetting agents or lathering agents, as levelling and anti-stain agents in polishes or emulsion paints, as corrosion inhibitors, evaporation retarders for solvents, and as waterrepellant and oil-repellant agents. |
