Abstract

Wynalazek dotyczy poliamfolitu, bedacego pochodna kwasu dimetylofosfinowego i kwasu 2-aminoetylofosfonowego, przedstawionego wzorem 1. Wynalazek dotyczy równiez sposobu wytwarzania poliamfolitu pochodnego kwasu dimetylofosfinowego i kwasu 2-aminoetylofosfonowego, wzorze 1, który polega na tym, ze w pierwszym etapie jedna czesc molowa kwasu fosfinowego poddaje sie reakcji z jedna czescia molowa kwasu 2-aminoetylofosfonowego i co najmniej jedna czescia molowa formaldehydu, a reakcje prowadzi sie w temperaturze 293-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu solnego, az do przereagowania substratów i utworzenia sie mieszaniny fosfinometylowanych pochodnych kwasu 2-aminoetylofosfonowego, która w drugim etapie poddaje sie reakcji polikondensacji, z co najmniej jedna czescia molowa formaldehydu, a reakcje prowadzi sie w temperaturze 293-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu solnego, az do zakonczenia polikondensacji.The invention relates to polyamolphite, which is a derivative of dimethylphosphinic acid and 2-aminoethylphosphonic acid, represented by formula 1. The invention also relates to a process for the production of polyamolphite of dimethylphosphinic acid derivative and 2-aminoethylphosphonic acid, formula 1, which consists in the first stage of one molar part of phosphinic acid are reacted with one mole part of 2-aminoethylphosphonic acid and at least one mole part of formaldehyde, and the reactions are carried out at a temperature of 293-373 K, in water, in the presence of an activator in the form of hydrochloric acid, until reactants react and the formation of phosphinomethylated mixtures derivatives of 2-aminoethylphosphonic acid, which in the second stage is subjected to a polycondensation reaction, with at least one molar part of formaldehyde, and the reaction is carried out at a temperature of 293-373 K, in water in the presence of an activator in the form of hydrochloric acid, until the end of polycondensation.
