Abstract

Przedmiotem zgłoszenia jest Sposób wytwarzania polioli, który prowadzi się tak, że w reaktorze umieszcza się 24 cz. wag. ligniny organosolv, od 90 do 120 cz. wag. glicydolu oraz od 240 do 300 cz. wag. węglanu etylenu, po czym zawartość reaktora miesza się i jednocześnie ogrzewa się ją do temperatury 190°C. Reakcję prowadzi się do uzyskania liczby epoksydowej wynoszącej zero. Następnie mieszaninę reakcyjną chłodzi się do temperatury 70°C, po czym wprowadza się do niej od 0,5 do 1,0 cz. wag. katalizatora i układ ogrzewa się do temperatury od 150°C do 170°C przy jednoczesnym jego mieszaniu i utrzymuje się go w tej temperaturze, przy jednoczesnym mieszaniu, do czasu zakończenia reakcji.The subject of the application is a method for producing polyols, which is carried out by placing 24 parts by weight of organosolv lignin, 90 to 120 parts by weight of glycidol, and 240 to 300 parts by weight of ethylene carbonate in a reactor, then mixing the reactor contents and simultaneously heating them to a temperature of 190°C. The reaction is carried out until the epoxy number is zero. The reaction mixture is then cooled to 70°C, after which 0.5 to 1.0 parts by weight of catalyst is introduced therein and the system is heated to a temperature of 150°C to 170°C while stirring and maintained at this temperature, while stirring, until the reaction is complete.
