Abstract

Wynalazek dotyczy sposobu wytwarzania poliamfolitu bedacego pochodna kwasu dimetylofosfinowego i hydroksylaminy, przedstawionego wzorem 1. Sposób wytwarzania poliamfolitu pochodnego kwasu dimetylofosfinowego i hydroksylaminy o wzorze 1, polega na tym, ze w pierwszym etapie jedna czesc molowa kwasu fosfinowego poddaje sie reakcji z jedna czescia molowa hydroksylaminy i co najmniej jedna czescia molowa 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 fosfinometylowanych pochodnych hydroksylaminy, która w drugim etapie poddaje sie reakcji polikondensacji z co najmniej jedna czescia molowa 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 poliamfolitu, który w trzecim etapie poddaje sie dosieciowaniu co najmniej jedna czescia molowa 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 poliamfolitu pochodnego kwasu dimetylofosfinowego i hydroksylaminy w postaci bialej bezpostaciowej substancji.The invention relates to a method for producing polyphosphite derivative of dimethylphosphinic acid and hydroxylamine, represented by the formula 1. The method for producing polyampholite derivative of dimethylphosphinic acid and hydroxylamine of formula 1 consists in that in the first stage one molar part of phosphinic acid is reacted with one molar part of hydroxylamine and at least one molar part of formaldehyde, and the reaction is 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 the formation of a mixture of phosphinomethylated derivatives of hydroxylamine, which in the second stage undergoes polycondensation reaction with at least one mole part of formaldehyde, and the reaction is 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 the formation of polyampolite, which in the third stage undergoes at least one molar part forms aldehyde, and the reaction is 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 the formation of a polyampholite derivative of dimethylphosphinic acid and hydroxylamine in the form of a white amorphous substance.
