Study of reactions of clean synthesis and chemical modification of the biodiesel and fusel oil for preparation of organic carbonate and carbamates using carbon dioxide in the presence of organocatalysts and heterogeneous catalysts
The project aims the study of reactions of synthesis and modification of biodiesel from soy, canola and cartamo oils with diverse heterogeneous catalysts and also in homogeneous phase. For synthesis of biodiesel, heteropoliacids will be studied among other catalysts such as basic supported organocatalisadores, complexes of Metal-chitosan, montmorillonites. In addition of methyl and ethyl esters, it is considered the use of main fusel oil alcohols (isobutyl and isopentyl alcohols) obtained by recycling of this by-product of Brazilian sugar and ethanol industry. The chemical modification of biodiesel will be performed by epoxidation and subsequent cycloaddition of carbon dioxide for production of carbonates and carbamates, with potential application in the area of new organic materials. These materials will be proceeding from clean sources, using as raw material vegetal oils, fusel oil and carbon dioxide. Physical chemical characterization and will be carried out using GC-MS, ESI-MS, RMN, FT-IR. These methodologies will be also used for low quality fatty ester recovery. (AU)
