Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania polieteroli, który prowadzi się tak, że w reaktorze umieszcza się od 20 do 30 cz. wag. glicydolu, od 20 do 30 cz. wag. wagowych glicerolu, od 60 do 80 cz. wag. węglanu etylenu i od 0,5 do 1 cz. wag. katalizatora, którym jest węglan potasu. Zawartość reaktora miesza się, zaś podczas mieszania do reaktora wprowadza się od 3,9 do 4,1 cz. wag. skrobi, po czym, podczas mieszania, zawartość reaktora ogrzewa się do temperatury co najwyżej 100°C i reakcję prowadzi się, do momentu ustąpienia efektu egzotermicznego, przy czym jeśli temperatura reakcji przekracza 180°C, układ chłodzi się. Po zakończeniu efektu egzotermicznego, reakcję prowadzi się w temperaturze z zakresu od 170°C do 190°C, przy ciągłym mieszaniu, do czasu jej zakończenia.
