Description
Summary:A brief overview of works in the field of mechanisms of reactions underlying the green chemistry of polyurethanes is presented. The main attention is paid to the processes of the formation of nonisocyanate urethanes from cyclocarbonates and amines and the thermal decomposition of acyl azides as a phosgene-free method for the preparation of isocyanates in statu nascendi. The results of the study of the functional composition of cyclocarbonate-containing triglycerides the derivatives of soybean and sunflower oils, and the prospects for using renewable plant raw materials for the synthesis of new urethanes are also discussed.
