dimethyl carbonate (DMC) is a chemical raw material with low toxicity, excellent environmental performance and wide application. As an important intermediate of organic synthesis, Dimethyl Carbonate (DMC) contains functional groups such as carbonyl group, methyl group and methoxy group in its molecular structure, and has various reaction properties. In production, it has the characteristics of safe use, convenient, less pollution and easy transportation. Dimethyl carbonate is a promising "green" chemical product because of its low toxicity
Storage and transportation precautions
Folded reserve attention
Flammable, its vapor mixed with air, can form an explosive mixture stored in a cool, dry, well-ventilated non-combustible warehouse.
Keep away from fire and heat. The storage temperature should not exceed 37ºC. Keep the container sealed. It should be stored separately from oxidants, reducing agents, acids, etc., and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark.
Storage area should be equipped with leak emergency treatment equipment and appropriate containment materials stored in a cool, dry, well-ventilated non-combustible warehouse.

Dimethyl carbonate is an important organic chemical intermediate with many uses, the following are some of the main application areas:
Replace phosgene as carbonylation agent: phosgene is a highly toxic gas, and dimethyl carbonate has a similar chemical reaction activity, can replace phosgene in many reactions, for the synthesis of polycarbonate, isocyanate, etc., so that the production process is safer and more environmentally friendly.
Methylation reagent: Dimethyl carbonate can be used as a mild methylation reagent in organic synthesis to introduce methyl groups into substrate molecules.
Synthesis of other organic compounds: can be used to synthesize a variety of organic compounds, such as diethyl carbonate, ethylene glycol dimethyl ether, etc., these compounds also have important uses in chemical production, such as as solvents, extractants and so on.
Coating solvent: dimethyl carbonate has good solubility, can dissolve a variety of resins and coating components, can be used as a coating solvent, help the coating uniform coating and drying, but also improve the leveling and gloss of the coating.
Reduced VOC emissions: Due to its relatively low volatile organic compound (VOC) content, the use of dimethyl carbonate in coatings and adhesives can reduce VOC emissions, meet environmental requirements, and help improve environmental quality.
Improve the bond performance: Adding dimethyl carbonate to some adhesives can interact with other components in the adhesive, improve the bond strength and stability of the adhesive, and make it show better performance in the bond of different materials.
Solvent: Dimethyl carbonate has a high dielectric constant and low viscosity, which can dissolve lithium salts, such as lithium hexafluorophosphate, etc., to form a stable electrolytic liquid system to ensure the effective transmission of lithium ions between the positive and negative electrodes of the battery.
Film forming additive: Adding an appropriate amount of dimethyl carbonate to the lithium battery electrolyte can form a stable passivation film on the electrode surface, which can prevent further reaction between the electrolyte and the electrode material, and improve the cycle life and safety of the battery.
Drug intermediates: It is an important intermediate for the synthesis of a variety of drugs, such as in the synthesis of anti-malarial drugs, cardiovascular drugs, nervous system drugs and other processes have applications, can be used to build the specific structure of drug molecules, so as to achieve the specific pharmacological activity of drugs.
Drug carrier: Dimethyl carbonate can react with some biocompatible materials to prepare drug carriers, which can be used to wrap and deliver drugs, achieve sustained release and targeted drug delivery, improve drug efficacy and reduce toxic side effects.
Pesticide intermediates: as a key intermediate for the synthesis of a variety of pesticides, such as for the production of carbamate pesticides, pyrethroid pesticides, etc., by reacting with other compounds, specific functional groups are introduced to give pesticides different insecticidal, bactericidal or herbicidal activities.
Solvent and diluent: In pesticide preparations, dimethyl carbonate can be used as a solvent and diluent, which helps to evenly disperse the active ingredients of pesticides in the preparation, improve the use effect and safety of pesticides, and reduce the pollution of pesticides to the environment.
Synthetic spices: can be used to synthesize some flavor compounds with specific aroma, such as in the process of synthesizing fruit ester spices, flower fragrances, etc., as reaction raw materials or intermediates, providing a green and efficient method for the synthesis of spices.
Fragrance extraction solvent: Due to its good solubility and relatively low toxicity, dimethyl carbonate can be used as a solvent for natural fragrance extraction, which can effectively extract fragrance components from plants, while not adversely affecting the quality and aroma of spices.
