| contents | <p>Aiming to the development of new synthetic routes for polyurethanes (PU) from raw materials exclusively from renewable sources, a 'green' synthesis of 1,8-diisocyanatooctane (DIO) was carried out from fatty acid derivatives by a method without the use of phosgene. The three-step synthetic route started from dimethyl sebacate, with the preparation of decanedihydrazide and decanedioyl diazide as intermediates, under nitrogen atmosphere. FTIR and ¹H NMR analyses confirmed the structure of the diisocyanate, which is a promising 'green' alternative to be used in the production of more sustainable polyurethanes by reaction with suitable polyols from biomass.</p> |
