This is a market dataset, representing the consumption market of the region. The dataset includes transport from the factory gate to the point of consumption, with transport services calculated based on the transport situation of the product in that region. The main applications of dimethyl carbonate include: (1) electrolyte in lithium-ion batteries (2) production of carbamate, polycarbonate, oxalate esters, oxalic acid, etc. (3) as a solvent used in coatings, adhesives, detergents, inks, batteries, and glue industries (4) it can also be used as a gas thickener in some organic synthesis reactions; this dataset includes primary raw materials, energy and atmospheric emissions in the production process, but infrastructure such as production equipment manufacturing and plant construction are not within the scope of the dataset boundaries; the data inventory is formed by merging data from multiple sources; DMC is produced by the ester exchange reaction of ethylene carbonate with methanol. Chemical reaction: C3H4O3 + CH3OH -> C3H6O3 + CH2O.
