Abstract

Wynalazek dotyczy chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i alaniny, o wzorze ogólnym I, w którym A oznacza fragment struktury kwasu dimetylofosfinowego, x oznacza liczbę takich fragmentów w poliamfolicie, natomiast B oznacza fragment struktury polialkilenopoliaminy, w którym n i p mogą być takie same lub różne i oznaczają liczby całkowite od 2 do 12, natomiast q jest liczbą struktur aminopolialkenowych i wynosi od 2 do 6, y oznacza liczbę fragmentów poliaminopolialkenowych w polimerze, natomiast C oznacza fragment struktury alaniny, a z oznacza liczbę takich fragmentów w poliamfolicie, przy czym wolne miejsca fragmentu A mogą się wiązać tylko z wolnymi miejscami we fragmencie B i C. Wynalazek obejmuje również sposób wytwarzania chiralnych poliamfolitów pochodnych kwasu dimetylofosfinowego, polialkilenopoliamin i alaniny, o wzorze ogólnym I, który polega na tym, że w pierwszym etapie jedną część molową kwasu fosfinowego poddaje się reakcji z co najmniej jedną częścią molową formaldehydu i co najmniej dwiema częściami molowymi grup -NH-, na które składa się suma grup -NH- pochodzących od polialkilenopoliaminy i grup -NH- pochodzących od alaniny, a reakcję prowadzi się w temperaturze 273-373K, w wodzie, w obecności aktywatora w postaci dowolnego kwasu Bronsteda, aż do przereagowania substratów i utworzenia się chiralnego poliamfolilu zawierającego fragmenty strukturalne kwasu dimetylofosfinowego, polialkilenopoliaminy i alaniny, który w trzecim etapie poddaje się dosieciowaniu co najmniej 0,5 części molowej formaldehydu. Otrzymany w wyniku chiralny poliamfolit wydziela się z mieszaniny poreakcyjnej przez dekantację, sączenie lub wirowanie, ewentualnie przez odparowanie lotnych składników pod zmniejszonym ciśnieniem.The invention relates to chiral polyampholytes derived from dimethylphosphinic acid, polyalkylene polyamines and alanine, with the general formula I, in which A is a fragment of the dimethylphosphinic acid structure, x is the number of such fragments in the polyampholyte, and B is a fragment of the polyalkylene polyamine structure, in which n and p may be the same or different and denote integers from 2 to 12, while q is the number of aminopolyalkene structures and ranges from 2 to 6, y denotes the number of polyaminopolyalkene fragments in the polymer, while C denotes a fragment of the alanine structure, and z denotes the number of such fragments in the polyampholyte, with the free places of the fragment A can only bind to free sites in fragment B and C. The invention also includes a method for preparing chiral polyampholytes derivatives of dimethylphosphinic acid, polyalkylene polyamines and alanine, with the general formula I, which consists in the fact that in the first step one mole of phosphinic acid is subjected to reaction with at least one mole part of formaldehyde and at least two mole parts of -NH- groups, which consist of the sum of -NH- groups derived from polyalkylene polyamine and -NH- groups derived from alanine, and the reaction is carried out at a temperature of 273-373K, in water, in the presence of an activator in the form of any Bronsted acid, until the substrates are reacted and chiral polyampholyl is formed containing structural fragments of dimethylphosphinic acid, polyalkylene polyamine and alanine, which is cross-linked with at least 0.5 mole of formaldehyde in the third step. The resulting chiral polyampholyte is isolated from the reaction mixture by decantation, filtration or centrifugation, optionally by evaporation of the volatile components under reduced pressure.
