“…On the one hand, methanol and CO 2 react to form the desired DMC, and water. On the other hand, the competitive reaction of methanol dehydration to form DME can also take place . Subsequent in series reactions of degradation of the previously formed species would explain the formation of the detected by‐products, thus, DMC could be degraded to OC or DME .…”

applications, and has been suggested as a potential gasoline additive. However, DMC has traditionally been produced from hazardous phosgene and CO routes, which encourages the interest in developing new processes. The aim of this work is to study the valorization process for the direct electrosynthesis of DMC from CO 2 and methanol using CH 3 OK and the ionic liquid 1-butyl-3-methylimidazolium bromide, avoiding the addition of carcinogenic compounds.This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

All rights reserved Accepted Article Accepted Article RESULTS: The evolution of the concentration of DMC was studied in a filter-press electrochemical cell with anodic and cathodic compartments separated by a Nafion 117 membrane, operating for 48 h. A final DMC concentration of 15.07 mmol·L -1 was observed.Moreover, analysis of the by-products obtained in the process revealed the formation of tetramethyl orthocarbonate and dimethoxymethane, which were detected and quantified in the liquid phase. A simplified reaction scheme was also proposed according to the results obtained.CONCLUSION: Unlike all previous works that used an undivided cell, the new experimental results of this study using a divided cell can serve as a reference for further research to overcome current limitations.

“…Near critical or supercritical state CO 2 reaction system can cause an increase in the mass transfer efficiency of the reactants and shift the reaction equilibrium to break the thermodynamic limitation of this reaction [78]. The effect of CO 2 pressure on the MeOH conversion and DMC yield was studied in order to assess the optimum CO 2 pressure for the catalyzed reaction.…”

“…Moreover, DMC shows great activity towards nucleophilic molecules (e.g., primary amines and phenols), thus makes it a valuable reactant for the production of other useful organics (Keller et al, 2010). For example, DMC acts as a carbonylation agent to replace the hazardous phosgene in the synthesis of polycarbonate or isocyanate, as well as a methylation agent to replace dimethylsulfate and methylhalides in related reactions (Tundo and Selva, 2002;Cao et al, 2012;Keller et al, 2010). In addition, DMC is widely used as fuel additive to significantly increase the octane number of fuel because of the high oxygen content of DMC (Pacheco and Marshall, 1997).…”

Global warming due to the accumulation of atmospheric CO 2 has received widespread attention in recent years. Although various CO 2 capture technologies have been proposed, using the captured CO 2 from power plants is increasingly popular because of concerns with regard to the safety of underground and ocean CO 2 storage. Various techniques related to utilization of CO 2 from the exhausted gas of power plants are discussed in this article. The existing and under-development technologies for CO 2 utilization in the world are briefly reviewed. Two categories, direct utilization of CO 2 and conversion of CO 2 to chemicals and energy products, are used to classify different forms of CO 2 utilization. Regarding the direct utilization of CO 2 , in addition to its use in soft drinks, welding, foaming, and propellants, as well as the use of supercritical CO 2 as a solvent, CO 2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO 2 into chemicals and energy products via this approach is a promising way to not only reduce the CO 2 emissions, but also generate more economic value. Since CO 2 is just a source of carbon without hydrogen, a clean, sustainable and cheap source of hydrogen should be developed. This article reviews the literature on the production of biofuel from microalgae cultivated using captured CO 2 , the conversion of CO 2 with hydrogen to chemicals and energy products, and sustainable and clean sources of hydrogen, in order to demonstrate the potential of CO 2 utilization.
