Diamine derivatives of dimerized fatty acids and bio-based polyether polyol as sustainable platforms for the synthesis of non-isocyanate polyurethanes
PublicationA series of environmentally friendly non-isocyanate polyurethanes (NIPUs) were successfully prepared via the polyaddition reaction of bio-based polyether polyol-based cyclic carbonate with diamine derivative of dimerized fatty acids. The syntheses of NIPUs were realized by the three-step method in the absence of toxic solvents and, importantly, the process of carbonation did not require the use of elevated pressure. The effect...

Sustainable synthesis of cyclic carbonates from bio‐based polyether polyol: the structure characterization, rheological behaviour and thermal properties
PublicationThe cycloaddition of CO2 to epoxides represents a green efficient method to form bis(cyclic carbonate)s. The main purpose of the work reported in this paper was to examine the effect of the gas flow rate (20, 40, 60 and 100 mL min–1) during carbonation on the conversion yield, chemical structure, rheological behaviour and thermal properties of the prepared compounds. A series of new bis(cyclic carbonate)s was obtained from bio‐based...

Synteza bio-cyklicznych węglanów z wykorzystaniem oligoeteroli różniących się masą molową
PublicationCykliczne węglany mogą być otrzymywane w wyniku cykloaddycji CO2 do eterów glicydylowych. Biorąc pod uwagę stopniowe wyczerpywanie się, a co za tym idzie, zauważalny wzrost cen substratów ropopochodnych należy wziąć pod uwagę zastąpienie surowców petrochemicznych przez związki pochodzenia naturalnego. Ponadto, wykorzystanie CO2 przyczynić się może do rozwoju perspektyw utylizacji tego gazu w syntezach organicznych. Otrzymanie węglanów...
