Title
(EN) RENEWABLE, CARBOHYDRATE BASED CO2-PHILES
(FR) GLUCIDE RENOUVELABLE A BASE DE COMPOSES CO2-PHILES
Abstract
(EN) A composition is disclosed comprising a carbohydrate-based material a dispersed in carbon dioxide. A general method for synthesizing inexpensive, renewable, non-toxic, non-fluorous, carbohydrate based CO2-philes is disclosed. These CO2-philes are soluble in carbon dioxide. Methods of making the composition are also disclosed. The methods and composition are useful in a variety of applications and can utilize gaseous, liquid and supercritical carbon dioxide. The methods and compositions are useful in the synthesis of surfactants and metal chelates for CO2, as a sizing substrate, in CO2-based coating processes, for impregnation and plasticizing cellulosic and non-cellulosic materials, in pharmaceutical applications, such as crystallization, dispersion and encapsulation of bioactive molecules in solid systems, in the densification of CO2, in the synthesis of biodegradable polymers in CO2, and for carbon dioxide removal, to name just a few.
(FR) L'invention concerne une composition contenant une matière à base de glucides dispersée dans du dioxyde de carbone, et un procédé général de synthèse d'un glucide exempt de fluor, non toxique, renouvelable et peu coûteux à base de composés CO2-philes. Ces composés CO2-philes sont solubles dans le dioxyde de carbone. Ladite invention a également trait à des procédés d'élaboration de la composition. On emploie les procédés et la composition susmentionnés dans une variété d'applications, ces procédés pouvant utiliser du dioxyde de carbone gazeux, liquide et supercritique. On utilise les procédés et les compositions dans la synthèse d'agents de surface et de chélates métalliques destinés au dioxyde de carbone, comme substrat de calibrage, dans des processus de revêtement à base de dioxyde de carbone de manière à imprégner et plastifier des matières cellulosiques et non cellulosiques, dans des applications pharmaceutiques, telles que la cristallisation, la dispersion et l'encapsulation de molécules bioactives dans des systèmes solides, dans la densification du dioxyde de carbone, dans le cadre de la synthèse de polymères biodégradables dans du dioxyde de carbone, et lors de l'élimination du dioxyde de carbone, entre autres.
