Synthesis and Applications of Group of Uniform Materials Based On Organic Salts GUMBOS and Supported Ionic Liquids SILs

Abstract

Supported ionic liquids (SILs) are heterogeneous materials, synthesized by immobilization of room temperature ionic liquids (melting point and#8804; 25oC) onto diverse solid support materials like mesoporous silica (SBA-15, MCM-41), amorphous silica gel, metal-organic frameworks, Merrifield resin, etc. The first half part of the dissertation includes the synthesis of silica-supported ionic liquids and their applications as adsorbents in adsorptive fuel desulfurization by taking model and real gasoline samples. Group of uniform materials based on organic salts (GUMBOS) are organic salts, that exhibit a solid phase at room temperature with melting points within the range of 25-250oC, comprised of oppositely charged bulky organic cationic and inorganic or organic anionic parts. The second half part of the thesis included the synthesis of a variety of GUMBOS and their application as organocatalysts in asymmetric synthesis. newlineThe present thesis is divided into two parts, PART-A and PART-B for SILs and GUMBOS respectively. Part A is divided into five chapters. This first chapter furnishes the background of SILs and second chapter incorporates a review of literature on synthesis and applications of SILs in the field of organic synthesis. The experimental section for whole study is included in the third chapter. The fourth chapter showed complete results and discussion part on the synthesis, characterization, and applications of all synthesized SILs in an adsorptive fuel desulfurization study. The fifth chapter covered conclusion and future perspectives of synthesized heterogeneous materials. In part B, sixth chapter covered a brief introduction on synthesis and applications of GUMBOS. All the published literature on GUMBOS was enclosed in seventh chapter. The experimental section and results/discussion part was covered in eighth and ninth chapter. The last chapter includes conclusion section of study which was described in chapter 8 and chapter 9 along with future perspectives. newline newline
