Recent progress in dimethyl carbonate synthesis using different feedstock and techniques in the presence of heterogeneous catalysts

Catalytic processes for the direct synthesis of dimethyl carbonate from CO2 and methanol: a review

“…12,13 DMC can be used as gasoline or diesel additives due to its high oxygen content (53%) and high-octane number (105). 14 Given its high dielectric constant and capability of solvating lithium salts, DMC is also an ideal solvent for lithium-ion batteries. 15 In addition, the usage of DMC as a green reagent for the replacement of toxic and hazardous chemicals, such as dimethyl sulphate, phosgene (COCl 2 ), and acetate esters, is also a potential application because of its low toxicity, low viscosity and good dissolving ability.…”

Synthesis of Dimethyl Carbonate via Transesterification of Ethylene Carbonate and Methanol using Recyclable Li/NaY Zeolite

“…As another kind of homogeneous catalysts, ionic liquids have also been investigated in this kind of reaction, showing excellent catalytic efficiency. However, the cumbersome synthetic process and energy‐intensive separation hinders their application in large scale production [18–19] . In this context, heterogeneous catalysis has drawn increasing consideration.…”

Dimethyl Carbonate Synthesis via Transesterification of Propylene Carbonate Using an Efficient Reduced Graphene Oxide-Supported ZnO Nanocatalyst

“…Dimethyl carbonate (DMC) is a green molecule which has found applications in several industries because of its versatility such as nontoxicity, biodegradability and also used as a vital reactant for the synthesis of diphenyl carbonate and glycerol carbonate. − It is used as a fuel additive in gasoline because of its high oxygen content of 53% . It is also employed as a solvent in the synthesis of polymers or pharmaceutical compounds, as an electrolyte in lithium-ion batteries, and biodiesel production. − There are several routes of producing DMC such as methanolysis of urea, transesterification of propylene carbonate (PC)/ethylene carbonate with methanol, and direct synthesis from methanol and carbon dioxide. − Various metal-based heterogeneous catalysts have been evaluated for the synthesis of DMC.…”

“…The hydrotalcite-type material of Mg–Al–NO 3 showed 54% EC conversion, whereas Mg–Al–CO 3 revealed a high PC conversion ratio of 72.2%. , The reason for this behavior could be the formation of a hydrogen bond between the internal −OH and −CO 3 ion which facilitates the activation of methanol. Therefore, it can be concluded that quantity of acidic and basic functional groups is an important parameter for achieving a high DMC yield …”

“…Therefore, it can be concluded that quantity of acidic and basic functional groups is an important parameter for achieving a high DMC yield. 1 Graphene is a promising carbon allotrope which has found several applications in industries. Graphene exhibits excellent physicochemical properties like a high surface to volume ratio, high electrical conductivity, high tensile strength, and so forth, which has attracted many researchers around the world.…”
