Nitrobenzyl Alcohol

A method for synthesizing of 2-nitrobenzaldehyde from 2-nitrobenzyl alcohol using ionic liquids (ILs) has been developed. The conversion of 2-nitrobenzyl alcohol and the selectivity of 2-nitrobenzaldehyde in the ionic liquids are higher than those in the traditional dichlorethane solvent. In addition, a reaction mechanism for the oxidation of 2-nitrobenzyl alcohol to 2-nitrobenzaldehyde is proposed.

The electrochemical reduction of carbon dioxide (CO2ER) is amongst one the most promising technologies to reduce greenhouse gas emissions since carbon dioxide (CO2) can be converted to value-added products. Moreover, the possibility of using a renewable source of energy makes this process environmentally compelling. CO2ER in ionic liquids (ILs) has recently attracted attention due to its unique properties in reducing overpotential and raising faradaic efficiency. The current literature on CO2ER mainly reports on the effect of structures, physical and chemical interactions, acidity, and the electrode–electrolyte interface region on the reaction mechanism. However, in this work, new insights are presented for the CO2ER reaction mechanism that are based on the molecular interactions of the ILs and their physicochemical properties. This new insight will open possibilities for the utilization of new types of ionic liquids. Additionally, the roles of anions, cations, and the electrodes in the CO2ER reactions are also reviewed.

As air pollution and green-house effect have caused numerous environmental problems in past decades, and increasing investigations have been focused on reducing the emission of harmful gas such as SOx. Oxidative desulfurization of fuel is considered as a promising method for its high efficiency and mild condition. Herein, ionic liquids supported urchin-liked meso-silica were facilely prepared and applied for heterogeneous oxidative desulfurization, which had a good dispersion of polyoxometalate ionic liquids. With the prepared materials, sulfur compounds can be efficiently removed. Moreover, the oxidation product was analyzed by GC-MS to further investigate reaction mechanism.

L-Proline derived ionic liquids (ILs) used as both solvent and catalyst were efficient for transformation of fructose and sucrose to 5-hydroxymethylfurfural (HMF) in the presence of water. Response surface methodology (RSM) was employed to optimize fructose dehydration process, and a maximum HMF yield of 73.6% could be obtained at 90°C after 50 min. The recycling of the IL exhibited an almost constant activity during five successive trials, and a possible reaction mechanism for the dehydration of fructose to HMF was proposed.
