Reaction Steps

A 3-necked flask, equipped with magnetic stirrer, reflux condenser and gas inlet tube, was charged with 121 g (0.5 mole) of ethyl perfluorobutyrate. The contents of the flask were heated to 60° C. and a slow stream of dimethylamine was passed in. The reaction is exothermic and the gas flow rate was adjusted to keep the temperature in the range of 60°-70° C. without external heat. Gas flow was continued until the weight increase of the flask showed absorption of 22.5 g (0.5 mole) of the amine.
