Polyhydroxyalkyl derivatives and polyetherols obtained from azacyclic compounds.
Part II. Reactions with formaldehyde and alkylene carbonates (in English)
Polimery 2011, No 6, 452
In this part of the paper modification of the method to obtain polyetherols from azacyclic compounds and oxiranes involving an initial hydroxyalkylation of formaldehyde was presented. Hydroxymethyl derivatives of azacyclic compounds were obtained. Very often they were better soluble in organic solvents than the initial compounds, even directly in oxiranes. These derivatives underwent further reaction with oxiranes so that polyetherols were obtained. The method of hydroxyalkylation with an application of ethylene and propylene carbonates was also presented. These carbonates constitute environment friendly solvents and reagents of azacyclic compounds.
Key words: heterocyclic compounds with nitrogen atoms, formaldehyde, oxiranes, alkylene carbonates.
