Application of Dimethyl Carbonate as Solvent and Reagent

Dehydrative Etherification Reactions of Glycerol with Alcohols Catalyzed by Recyclable Nanoporous Aluminosilicates: Telescoped Routes to Glyceryl Ethers

“…Reactions of the less activated diphenylmethanol (DPM) 1d proceeded more slowly, and gave only moderate yields of 2d (entry 9). Reactions carried out with alcohols 1b – 1d under similar conditions in chloroform displayed no significant improvements over DMC, highlighting the effectiveness of DMC as a sustainable and less toxic alternative to commonly employed halogenated solvents …”

“…Reactions carried out with alcohols 1b−1d under similar conditions in chloroform displayed no significant improvements over DMC, highlighting the effectiveness of DMC as a sustainable and less toxic alternative to commonly employed halogenated solvents. 35 An alternative strategy that could effectively address both the issues encountered with the formation of the dimeric ether product, and hence improve selectivity for the 1-alkylated ether products, is to reduce the polarity of glycerol by selective protection of one or more of the hydroxyl groups. This is a widely employed but relatively inefficient strategy, where the protected glyceryl derivative is first synthesized and isolated, and then reacted with an alkylating agent in a separate reaction.…”

Etherification Reactions of Furfuryl Alcohol in the Presence of Orthoesters and Ketals: Application to the Synthesis of Furfuryl Ether Biofuels

“…We next undertook a study of the etherification reaction in dimethyl carbonate (DMC), a solvent which has been proposed as an alternative environmentally benign replacement for more traditional solvents. 26 These reactions proceeded in the absence of an alcohol solvent, with the orthoester itself acting as a source of alcohol. As previously, reaction of FAlc with one equivalent of TMOF in the absence of catalyst provided no ether products ( Table 3, entry 1).…”

Optimization of Catalytic Distillation for the Synthesis of Dimethyl Carbonate by Response Surface Methodology

“…Dimethyl carbonate (DMC) is an important environmentally chemical intermediate, which is widely used in various fields because of its various chemical reaction activities and unique physical properties [1] . As a clean organic chemical reagent, DMC, on the one hand, can replace phosgene, dimethyl sulfate, and other highly toxic substances for carbonylation and methylation reactions to generate a variety of essential chemical products; [2] On the other hand, DMC has been widely used in lithium‐ion batteries in recent years due to its high ionic conductivity, low melting point, high boiling point, chemical stability, and electrochemical stability [3] . Third, DMC can also be used as a low toxic solvent [4] and a fuel additive [5] due to its good solubility and high oxygen content (53.3 %).…”
