“…The maximum loading is dependent on the number of silanols on the surface of SBA-15 and can reach 6.5 mmol g À1 , which is obviously higher than the amount of amine that could be introduced. 152,153 Traditionally, DMC is synthesized in the presence of homogeneous strong bases. 19).…”

Mesoporous solid bases are extremely desirable in green catalytic processes, due to their advantages of accelerated mass transport, negligible corrosion, and easy separation. Great progress has been made in mesoporous solid bases in the last decade. In addition to their wide applications in the catalytic synthesis of organics and fine chemicals, mesoporous solid bases have also been used in the field of energy and environmental catalysis. Development of mesoporous solid bases is therefore of significant importance from both academic and practical points of view. In this review, we provide an overview of the recent advances in mesoporous solid bases, which is basically grouped by the support type and each category is illustrated with typical examples. Cooperative catalysts derived from the incorporation of additional functionalities (i.e. acid and metal) into mesoporous solid bases are also included. The fundamental principles of how to design and fabricate basic materials with mesostructure are highlighted. The mechanism of the formation of basic sites in different mesoporous systems is discussed as well.

“…This catalytic system, using the SILP concept, was tested over 50 h time-on-stream, achieving a total turnover number of more than 600, which is an unprecedented productivity in the gasphase homogeneous oxycarbonylation. 79 The process design requires a smaller reactor size than the existing technology, in order to obtain the same productivity, which makes the SILP carbonylation concept potentially interesting for technical applications.…”

“…Nevertheless, researches on oxy-carbonylation of methanol and methyl nitrite are continually explored, since these routes are the main source of industrial produced DMC, especially the development of new catalysts. Recently, the use of the Cl-free catalyst Cu/ starch [55] or supported ionic liquid phase ([OMA]Br) over polymer-based in order to overcome the Cu deactivation [56] was reported. A reactor design for the production of dimethyl carbonate from the oxidative carbonylation of methanol is disclosed in this patent.…”

Review for the Direct Synthesis of Dimethyl Carbonate

et al. 2014

This review summarizes the state-of-the-art for direct synthesis of dimethyl carbonate (DMC) from carbon dioxide and methanol. In addition, conventional and alternative processes are also discussed in order to understand the advantages and disadvantages of the direct synthesis of DMC. Furthermore, the major applications of DMC are described: solvent, fuels additive, and building block for organic synthesis. The major drawbacks of the direct synthesis of DMC are the low yield and reaction rate, mostly induced by the highly stable carbon dioxide molecules. The development of novel catalyst and strategies to enhance the DMC yield -such as dehydrating agents that remove the water from the reacting mixture -are pointed out as the key solution for this route. Therefore, the main catalysts (homogeneous and heterogeneous catalysts) used so far are presented, together with the respective operating conditions and catalyst performance. The use of different dehydrating agents to increase the DMC yield is also discussed.
