g u00b1 5 g di water the mixture is stirred for another about 2 hours 30 minutes to 3 hours 30 min but most preferrably 3 hours at about 75 u00b0 c to about 85 u00b0 c but most preferrably about 80 u00b0 c thereafter appropriate amounts of diethanolamine were added for neutralization by stoichiometry the product is obtained by extraction with ethyl ether and distillation in one embodiment of the present invention 100 g u00b1 10 g 0 67 mole u00b1 0 07 mole methydichorophosphate mepocl 2 is added drop wise to a mixture of 300 ml u00b1 30 ml anhydrous ether 131 93 g u00b1 13 g 1 67 mole u00b1 0 17 mole pyridine and 1 67 mole u00b1 0 17 mole 3 3 3 trifluoro 1 propanol under stirring at approximately about 3 u00b0 c to 7 u00b0 c but most preferrably 5 u00b0 c the mixture is refluxed for about 1 hour 30 minutes to 2 hours 30 min but most preferrably about 2 hours the reaction mixture is cooled in a refrigerator and pyridinium salt is then filtered the filtrate is washed first by 10 w t sulfuric acid solution in nacl saturated distilled water and then by nacl saturated distilled water alone the resultant organic phase is dried over mgso 4 and then fractionated 3 times final distillates of the products are collected the technology for treating a fabric with superoleophobic and superhydrophilic chemicals to form fabric filters may also find use in.
