In this study, an ionic liquid incorporated modified MOF was synthesized to serve as an efficient electrolyte system for Li-ion batteries. Further, the MOF (IL) was doped with a lithium salt, lithium bis(triflouromethylsulfonyl) imide (LiTFSI) by a modified procedure. Samples with varying amount of MOF (IL) in ionic liquid were prepared, characterized and evaluated for their electrochemical behavior. A high conductivity in order of 10 −2 -10 −3 Scm −1 at 51 • C and a low activation energy of ion transport was observed in all samples. The systems showed high electrochemical stability to be employed as gel electrolyte in Li ion secondary batteries. These systems showed highly reversible capacity of over 3000 mAhg −1 in the charge-discharge studies carried out after fabricating anodic half-cell composed of Si/electrolyte/Li. These results illustrate the feasibility of the prepared modified MOF (IL) as potential solid state electrolytes for Li ion secondary batteries.

“…19 In a typical reaction, 1-methylimidazole (1 mol) and 1-chlorobutane (1.1 mol) were dissolved in acetonitrile g Aldrich), and H 2 O (130 g). The mixture was stirred for 15 min, then three equal volumes of the gel were poured into 60-mL Teflon-lined stainless steel autoclaves and stored in an oven at 160 °C for 24 h to 7 days either without stirring or with mechanical stirring (60 rpm).…”

In this work, the synthesis of zeolites using 1-butyl-3-methylimidazolium chloride [C 4 MI]Cl as a structure-directing agent was investigated. The organic cation shows effectiveness and selectivity for the syntheses of TON zeolites under different reaction conditions compared to the traditional structuredirecting agent, 1,8-diaminooctane. The 1-butyl-3-methylimidazolium cation lead to highly crystalline materials and its role as OSDA in our synthesis conditions has been confirmed by characterization techniques. ICP-OES confirms the presence of Al in the samples and 27Al MAS NMR analysis indicated that aluminum atoms were incorporated in tetrahedral coordination. Scanning electron microscopy indicated that changing the crystallization condition (static or stirring), zeolites with different crystal size were obtained, which consequently affects the textural properties of the zeolites. Moreover, varying some synthesis parameters MFI zeolite can also be obtained.

“…Diante da maior disponibilidade de halogenetos de alquila, a rota sintética mais utilizada para líquidos iônicos de isentos de íons halogenetos envolve a alquilação, com o isolamento do sal quaternário (C n mimX), 27 seguida de troca do ânion com sais de prata e metais alcalinos (rota 1). 28,29 Apesar da queda de economia de átomos na segunda etapa (formação do sal M[X]), esta rota mostra-se a mais versátil porque possibilita a introdução de um amplo espectro de ânions.…”

“…17 Ainda que o uso de solventes seja reduzido, estes são fundamentais na etapa de quaternização para atenuar o superaquecimento (reação exotérmica) e aumentar a velocidade em relação à reação sem solvente. 32 Além disso, o consumo completo do substrato 2 (e de outras bases de Lewis) em condições de aquecimento convencional demanda energia (refluxos de 6-48h) e excesso do agente alquilante, 27 principalmente com cloretos de alquila que são facilmente acessíveis, porém menos reativos do que os brometos e iodetos correspondentes. Desta forma, o êxito das rotas mostradas acima, traduzido pela redução do fator E, está relacionado ao consumo total dos substratos na etapa de quaternização, preferencialmente na ausência de solvente.…”

Ionic liquids have been used as green solvents in synthesis and catalysis due to their negligible vapor pressure, high stability and formation of biphasic systems. In addition, the exclusive presence of ions enables the development of efficient synthetic methodologies based on both ionic liquids as solvent and microwave heating. However, the usual protocols to preparation of ionic liquids demand large volume of volatile organic solvents and demand great energy consumption, what are not in agreement with Green Chemistry concept. On the other side, microwave activation arises as an important tool aiming waste reduction and energy economy in ionic liquid synthesis. In this review is discussed the evolution of the microwave ovens in ionic liquid synthesis and the influence of the substrate on the experimental conditions. Keywords: Green Chemistry; methylimidazole; alkylation. ResumoOs líquidos iônicos são usados como solventes verdes em síntese e catálise devido à pressão de vapor desprezível, alta estabilidade e formação de sistemas bifásicos. Além disso, a presença exclusiva de íons possibilita o desenvolvimento de metodologias sintéticas eficientes baseadas em líquidos iônicos como solventes e no aquecimento por micro-ondas. Entretanto, os protocolos usuais para a preparação de líquidos iônicos demandam grandes volumes de solventes orgânicos voláteis e alto consumo de energia, o que não está em acordo com o princípio de Química Verde. Por outro lado, a ativação por micro-ondas surge como uma importante ferramenta para a redução de rejeitos e economia de energia na síntese de líquidos iônicos. Nesta revisão é discutida a evolução do uso dos fornos de micro-ondas na síntese de líquidos iônicos e como as condições experimentais são ajustadas de acordo com os substratos.Palavras-chave: Química-Verde, metil-imidazol; alquilação.
