Title
(EN) POLYOLS FROM PROTEIN BIOMASS
(FR) POLYOLS PROVENANT DE BIOMASSE PROTÉINIQUE
Abstract
(EN) A process of producing multi-hydroxy polyols, the process comprising providing a biomass material and transamidating the biomass material with an amine selected from the group consisting essentially of a diamine and an alkanolamine, to provide low molecular weight derived amino-acids or derived oligomers of proteins. Thereafter, reacting the derived amino-acids or derived oligomers with a carbonate to provide hydroxyl terminated urethane oligomers.
(FR) L'invention concerne un procédé de production de polyols à plusieurs groupes hydroxy, le procédé consistant à utiliser un matériau de biomasse et à transamider la matière de la biomasse avec une amine choisie dans le groupe constitué essentiellement par une diamine et une alcanolamine, de manière à obtenir des aminoacides dérivés ou des oligomères dérivés, de faible poids moléculaire, de protéines. Ensuite, on fait réagir les aminoacides dérivés ou les oligomères dérivés avec un carbonate pour obtenir des oligomères d'uréthane à terminaison hydroxyle.
