Summary
In view of a study on the preparation and properties of polyurethanes containing furan rings, it was deemed necessary to carry out a preliminary investigation on the synthesis and characterization of simple furanic urethanes given the paucity of information available on this family of compounds. Three types of combinations were tested, viz; (i) furanic alcohols plus non-furanic isocyanates; (ii) non-furanic alcohols plus furanic isocyanates; (iii) furanic alcohols plus furanic isocyanates. The 21 urethanes thus obtained were fully characterized: they are stable (with one exception) and their synthesis is not marred by secondary reactions, ie the furan ring does not introduce “side effects”.
