Abstract

Wynalazek dotyczy poliamfolitu, bedacego pochodna kwasu dimetylofosfinowego i amoniaku przedstawionego wzorem ogólnym 1. Wynalazek dotyczy równiez sposobu wytwarzania poliamfolitu pochodnego kwasu dimetylofosfinowego i amoniaku, który polega na tym, ze w pierwszym etapie trzy czesci molowe kwasu fosfinowego poddaje sie reakcji z dwiema czesciami molowymi amoniaku i co najmniej dwiema czesciami molowymi formaldehydu, a reakcje prowadzi sie w temperaturze 273-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu solnego, az do przereagowania substratów i utworzenia sie mieszaniny kwasów aminometylofosfinowych, która w drugim etapie poddaje sie reakcji polikondensacji z co najmniej dwiema czesciami molowymi formaldehydu, az do zakonczenia reakcji, po czym w trzecim etapie poliamfolit poddaje sie dosieciowaniu co najmniej dwiema czesciami molowymi formaldehydu, a reakcje prowadzi sie w temperaturze 273-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu solnego, a otrzymany poliamfolit wydziela sie z mieszaniny poreakcyjnej przez odparowanie lotnych skladników.The invention relates to polyampholite, a derivative of dimethylphosphinic acid and ammonia represented by general formula 1. The invention also relates to a process for the production of polyampholite derivative of dimethylphosphinic acid and ammonia, which consists in the first stage that three molar parts of phosphinic acid are reacted with two molar parts of ammonia and at least two molar parts of formaldehyde, and the reactions are carried out at a temperature of 273-373 K, in water, in the presence of an activator in the form of hydrochloric acid, until reacting of the substrates and forming a mixture of aminomethylphosphinic acids, which in the second stage undergoes polycondensation reaction with with at least two molar parts of formaldehyde until the reaction is completed, after which in the third stage the polyampolite is crosslinked with at least two molar parts of formaldehyde, and the reactions are carried out at a temperature of 273-373 K, in water in the presence of an activator in the form of hydrochloric acid, and received Polish amphipolite is separated from the reaction mixture by evaporation of volatile components.
