A comprehensive review on zinc-based mixed metal oxide catalysts for dimethyl carbonate synthesis via urea alcoholysis process

Decarbonylation of dimethyl oxalate to dimethyl carbonate over Cs2CO3/HZSM-5

“…Dimethyl carbonate (DMC) is a green chemical with low toxicity and easy degradability, [1][2][3] which has extensive applications in the fields of pharmaceuticals, coatings, and lithium-ion battery electrolytes. 4,5 Currently, the main techniques used for synthesizing DMC include methanol phosgenation, 6 oxidative carbonylation of methanol, 7 tranesterification, 8 urea alcoholysis, 9,10 direct synthesis from carbon dioxide, [11][12][13] and decarbonylation of dimethyl oxalate. 14 The phosgene process was the first to be used for large-scale production of DMC and has been limited in the industry owing to the toxic raw material involved.…”
