Product Introduction:
Dimethyl Carbonate (DMC for short), chemical formula C3H6O3, is an important organic compound with the molecular formula of C3H6O3. DMC exists as a colorless transparent liquid with an aromatic scent, featuring a boiling point of 90.2 deg C, melting point of -4 deg C and density of around 1.07 g/cm3. While water insoluble, DMC miscible with alcohol, ether ester solvents as well as other organic solvents proving excellent solubility.
Dimethyl Carbonate has strong chemical reactivity. As its structure contains both ester and carbonyl groups, its ester group can participate in transesterification reactions such as transesterification, alcoholysis and ammonolysis reactions; its carbonyl group can facilitate ammonolysis reactions. Furthermore, Dimethyl Carbonate can also serve as a methylation reagent to produce compounds like methylphenol and N-methylamine; unlike traditional methylation reagents (such as dimethyl sulfate), it produces only one by-product (methanol), making Dimethyl Carbonate widely considered green chemical.
Dimethyl Carbonate has many applications in industry. First of all, it serves as an effective low-toxicity solvent that has gradually replaced traditional benzene and ketone solvents as an industrial production solvent. Furthermore, in medicine and pesticide synthesis it serves as an essential intermediate in synthesizing a range of nitrogen-containing, oxygen-containing and sulfur-containing organics essential components of various drugs and pesticides; additionally it’s frequently employed as a lithium battery electrolyte solvent due to its high purity and good electrochemical stability – two uses which make Dimethyl Carbonate indispensable industrially.
Dimethyl Carbonate stands out in terms of environmental protection and safety; in Europe it is classified as a non-toxic chemical with low toxicity levels and biodegradability properties. Unfortunately, however, its flammability poses serious fire and explosion risks; strict fire and explosion safety precautions must be observed during storage and transportation, keeping away from oxidizing agents and high temperature environments.

1.Dimethyl Carbonate is one of the main solvents of lithium battery electrolytes. When creating lithium battery electrolyte solutions, Dimethyl Carbonate is often mixed with other carbonate ester solvents (such as vinyl carbonate, propylene carbonate or diethyl carbonate ) to form an electrolytic liquid system with excellent performance and conductivity improvements. With rapid developments within both new energy vehicle industry and energy storage market, Lithium battery electrolyte demand continues to expand exponentially.
2. Chemical Industry
Dimethyl Carbonate is an indispensable intermediate of organic synthesis, used in multiple organic reactions including carbonylation, methylation, methoxylation and carbonyl methylation. It can replace toxic substances such as phosgene or dimethyl sulfate when synthesizing polycarbonates, isocyanates, polyurethanes or polycarbonate diols – products used widely across plastics, coatings, adhesives and other industries with broad market opportunities.
3.Dimethyl Carbonate has become an indispensable reagent in the synthesis of pesticides, offering green and eco-friendly carbonylation and methylation reagent solutions. It can replace traditional reagents such as phosgene and dimethyl sulfate for producing pesticides and their intermediates such as sulfonylurea herbicides, carbendazim, carbaryl pesticides and more, improving efficiency while decreasing environmental pollution. For instance, its carbonylation properties allow its use as an improvement mechanism which both increases efficiency while decreasing environmental pollution levels during production processes involving these types of herbicide synthesis processes.
4. Medicine
Dimethyl is also an integral component in the pharmaceutical synthesis of Carbonate, an anti-infective, analgesic, vitamin and central nervous system drug that has multiple applications. For example, it serves as an important raw material in producing quinolone antibiotics such as Ciprofloxacin, Norfloxacin and Piperidol acid, all highly sought-after medications with good efficacy, low price and safety properties – their market demand being high as a result. In addition to replacing toxic dimethyl sulfate as methylating agent it also acts as an important methylating agent thus decreasing exposure to highly toxic chemicals during production processes of pharmaceutical intermediate production processes.
5. Other Uses
Dimethyl Carbonate can also be used as a non-toxic solvent in coatings, adhesives and developer industries to improve product performance while meeting environmental protection regulations outlined by green chemistry development requirements. Furthermore, Dimethyl Carbonate can also be added as a gasoline additive to increase octane number while decreasing emissions from automobile exhaust emissions.
1. Compared with many traditional solvents, dimethyl carbonate is less toxic and more harmless to the human body. For example, solvents such as benzene, toluene, and methylene chloride can cause death at low concentrations. Therefore, dimethyl carbonate is considered to be a green solvent, which can be used in chemical reactions, pharmaceutical industry, food industry, etc., without harming the environment and health.
2. Dimethyl carbonate can be biodegraded rapidly after use, so there is less pollution to the environment. In addition, its low volatility makes it difficult to evaporate into harmful gases or pollute the atmosphere. These characteristics are in line with the current demand for green chemistry and environmentally friendly products.
3. Dimethyl carbonate can dissolve a variety of organic compounds, even some compounds that are insoluble in water. It can be used as an alternative to traditional solvents, increasing solubility and reducing the amount of harmful solvents in coatings, paints and detergent formulations.
4. In the lithium battery electrolyte, dimethyl carbonate shows good electrochemical stability, and can be mixed with ethylene carbonate EC, diethyl carbonate DEC and other solvents to form an efficient, safe and stable electrolytic liquid system.
5. Dimethyl carbonate is a highly active chemical compound that can react with a variety of organic compounds to produce carbonate compounds. As an important intermediate in organic synthesis, it can be used to synthesize a variety of high-value chemicals: pesticides, pharmaceutical products, plastics, etc.
6. Compared with some traditional organic solvents, dimethyl carbonate has low flammability and high ignition point, so it can be regarded as relatively safe in some high-risk chemical applications. In addition, its stability is also relatively good, and it is not prone to violent reactions or decomposition.
