Resumo: The acceptance that climate change is direct related to increasing greenhouse gas emissions, carbon dioxide (CO2) in particular, and the need to improve synthesis with reusable inputs are some of the current concerns. Thus, this thesis aims to contribute to the development of new catalytic materials for the processes that explore the possibilities of production of organic carbonates from CO2. Cyclic carbonates have several applications. Furthermore, their production from CO2 would represent a huge step towards mitigating environmental impacts. For this, new ionic liquids (ILs) of imidazolium ([bmim+]) and tetra-n-alkylammonium ([TBA+]) cations with anions derived from surfactant salts ([C12SO4-], [C12ESO4-], [C12BSO3-], [C12SAR-]) were synthesized and tested as catalysts of different cycloaddition of CO2 in epoxides. ILs were characterized by FTIR, 1H-NMR, TGA and DSC. The [Cl-], [Na+] and moisture residues determined the purity of the material. The ILs showed good activity in propylene carbonate (PC) synthesis, 79.2% of conversion and 87.7% of selectivity when [TBA][C12SO4] was used. For this reaction, catalyst kept its activity for at least 5 cycles. In the synthesis of styrene carbonate (SC), [TBA] [C12BSO3] was the most efficient IL reaching 81.4% of conversion and 87.0% of selectivity. This IL also showed significant activity in the synthesis of glycidyl isopropyl ether carbonate (GC) and epichlorohydrin carbonate (EC)

Sendo assim, esta tese visa contribuir para o desenvolvimento de novos materiais ativos como catalisadores de processos que exploram as possibilidades de produ??o de carbonatos org?nicos a partir de CO2. Os carbonatos c?clicos possuem diversas aplica??es. Al?m disso, a sua produ??o partindo de CO2 representaria um enorme passo para a mitiga??o dos impactos ambientais. Para isso, novos l?quidos i?nicos (LIs) de c?tions imidaz?lios ([bmim+]) e tetra-n-alquilam?nio ([TBA+]) com ?nions derivados de sais surfactantes ([C12SO4-], [C12ESO4-], [C12BSO3-], [C12SAR-]) foram sintetizados e testados como catalisadores de diferentes cicloadi??es de CO2 em ep?xidos. Os LIs foram caracterizados por FTIR, 1H-RMN, TGA e DSC. A pureza do material foi determinada pelos residuais de [Cl-], [Na+] e umidade. Os LIs mostraram boa atividade na s?ntese do carbonato de propileno (PC), atingindo 79,2% de convers?o e 87,7% de seletividade quando utilizado o [TBA][C12SO4]. Para esta rea??o o catalisador manteve sua atividade por pelo menos 5 reciclos. Na s?ntese do carbonato de estireno (SC) o [TBA][C12BSO3] se mostrou o LI mais eficiente atingindo 81,4% de convers?o e 87,0% de seletividade. Este LI tamb?m mostrou significativa atividade na s?ntese do carbonato de glicidil isopropil ?ter (GC) e no carbonato de epicloridrina (EC).Submitted by PPG Engenharia e Tecnologia de Materiais (engenharia.pg.materiais@pucrs.br) on 2018-12-21T19:16:15Z No. of bitstreams: 1 Tese Michele.pdf: 16487426 bytes, checksum: c9a39bc52c2251aaec6d2a9e780e5095 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2018-12-26T15:55:04Z (GMT) No. of bitstreams: 1 Tese Michele.pdf: 16487426 bytes, checksum: c9a39bc52c2251aaec6d2a9e780e5095 (MD5)Made available in DSpace on 2018-12-26T16:08:18Z (GMT).
