Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania pięcioczłonowych węglanów cyklicznych z polioli polieterowych, polegający na tym, że w pierwszym etapie poliol polieterowy poddaje się reakcji z epichlorohydryną w obecności katalizatora w temperaturze od 70 do 100°C, w drugim etapie przeprowadza się dehydrochlorowanie za pomocą wodorotlenku w temperaturze od 40 do 60°C. W trzecim etapie przeprowadza się cykloaddycję gazowego dwutlenku węgla w temperaturze od 70 do 140°C. Jako substrat stosuje się poli(glikol trimetylenowy) pochodzenia naturalnego o średniej masie cząsteczkowej od 250 do 2700 g/mol, zaś trzeci etap przeprowadza się pod ciśnieniem atmosferycznym z kontrolowaną prędkością przepływu gazu od 20 do 100 ml/min.The subject of the application is a method of obtaining five-membered cyclic carbonates from polyether polyols, which consists in reacting the polyether polyol with epichlorohydrin in the presence of a catalyst at a temperature of 70 to 100 ° C in the first stage, and in the second stage carrying out dehydrochlorination with hydroxide at a temperature of from 40 to 60 ° C. In the third step, cycloaddition of gaseous carbon dioxide is carried out at a temperature of 70 to 140 ° C. As substrate, poly (trimethylene glycol) of natural origin with an average molecular weight of 250 to 2700 g / mol is used, and the third step is carried out at atmospheric pressure with a controlled gas flow rate of 20 to 100 ml / min.
