METHOD FOR CATALYTIC N-POLYFLUOROALKYLATION OF POLYETHYLENE POLYAMINE WITH POLYFLUORINATED ALCOHOL Russian patent published in 2024 - IPC C07C211/48 

FIELD: organofluorine chemistry.

SUBSTANCE: invention relates to a method for catalytic N-polyfluoroalkylation of polyethylene polyamines with polyfluorinated alcohols, reaction products of which can be used as surfactants, reactive modifiers of polymer materials to increase thermal and hydrolytic stability, fire-, light- and wear resistance, impart oil- and water-repellent properties. Method for catalytic N-polyfluoroalkylation of polyethylene polyamine with a polyfluorinated alcohol involves treating an amine with a polyfluorinated alcohol while heating, with subsequent separation of the reaction product, wherein the amine used is polyethylene polyamine, and the reaction is carried out in a sealed ampoule at 80 °C, under the effect of ultrasound with frequency of 40 kHz for 2 hours, with subsequent heating to 120 °C for 4 hours, in the presence of organomodified montmorillonite with polyfluoroalkyl groups with molar ratio of polyethylene polyamine, polyfluorinated alcohol and organomodified montmorillonite equal to 1:1:0.01, respectively.

EFFECT: high output of the product of N-polyfluoroalkylation, degree of conversion of the starting reagents and low proportion of side reactions.
