What is DMC liquid?
DMC is a clear colorless liquid synthesized from carbon monoxide and methanol as same as DMC by using UBE’s proprietary nitrite technology, and used as a pharmaceutical intermediate. It is being employed as a raw material for organic synthesis reactions such as methylation, carbonylation, and carbomethoxylation.
Is dimethyl carbonate an ester?
Dimethyl carbonate (DMC) is an organic compound with the formula OC(OCH3)2. It is a colourless, flammable liquid. It is classified as a carbonate ester.

What is dimethyl carbonate used for?
It is used in the manufacturing of lithium-ion batteries, production of polycarbonates, lubricants, polyurethanes, cleaning and degreasing solvents, construction materials such as paints and adhesives, fuel additives, and in biodiesel production. Dimethyl Carbonate (DMC) is also considered a green reagent.
Is DMC a green solvent?
Dimethyl carbonate (DMC) is an established solvent and a green reagent which continues to attract attention. It is a nonpolar aprotic solvent with good miscibility with water, biodegrades readily in the atmosphere, and is non-toxic.
How is dimethyl carbonate made?
Dimethyl Carbonate–Methanol Separation DMC is prepared industrially by the reaction of methanol with carbon monoxide and oxygen. The process produces a mixture of methanol and DMC, which cannot be separated by simple distillation owing to the formation of an azeotrope.
Is carbonic acid an ester?
Carbonic acid monoalkyl esters are elusive molecules. The organic chemistry textbook Houben–Weyl reads as “The monoesters of carbonic acid, known as hemicarbonic acids, are formed by the reaction of alcohols with carbon dioxide. They are unstable and undergo decomposition to alcohols and carbon dioxide.
How is diethyl carbonate made?
It can be made by reacting phosgene with ethanol, producing hydrogen chloride as a byproduct.
How safe is dimethyl carbonate?
DMC is still safer than acetone, methyl acetate and methyl ethyl ketone from a flammability point of view. DMC has a recommended exposure limit (REL) limit of 100 ppm by inhalation over an 8-hour work day, which is similar to that of a number of common industrial solvents (toluene, methyl ethyl ketone).
How do you make DMC?
There are two main sections in the process flowsheet: the synthesis of urea and the synthesis of DMC. In the urea synthesis stage, carbon dioxide and ammonia react to synthesize urea. Then, urea and methanol react in two steps to produce DMC. The synthesis of urea alone from sustainable ammonia is also studied.
What is the chemical name of carbonic acid?
Carbonic acidCarbonic acid / IUPAC ID
carbonic acid, (H2CO3), a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water.
