The usage of DMC

Dimethyl carbonate of Evergreen Chemical is insoluble in water, but can be mixed with alcohol, ether, ketone and almost all organic solvents. DMC, with low toxicity, was listed as a non-toxic product in Europe in 1992. It is an environment-friendly chemical material in line with the requirements of modern "clean technology".

Dimethyl carbonate (DMC) is an important organic chemical intermediate. Because its molecular structure contains carbonyl, methyl, methoxide and carbonyl methoxide, it can be widely used in organic synthesis reactions such as carbonylation, methylation, methoxylation and carbonyl methylation. It used in the production of polycarbonate, isocyanate, polyurethane, polycarbonate glycol, allyl diethylene glycol carbonate, methyl amino formic acid naphthalene ester (carbaryl), benzene methyl ether ammonium, four methyl alcohol, long chain alkyl carbonate, carbon hydrazide, malonic ester, propylene urethane, diethyl carbonate, three phosgene, furazolidone, hydrazine methyl formate, aniline methyl formate and other chemical products.

1、Instead of phosgene to synthesize polycarbonate

2、As a non-toxic or low-toxic solvent, alternative to the traditional toxic solvents such as toluene, xylene, acetone, butanone, ethyl acetate, butyl acetate, etc., DMC used in the paint (nitro paint, furniture paint, automotive paint) and adhesive industry.

3、In the field of pesticides, DMC is mainly used to produce methyl isocyanate and then some carbamate pesticides. The varieties of pesticides that can be produced include: carbaryl, baylor, carbaryl, budweiser, methadol, etc.

4、In the part of medicine, it is mainly used to synthesize anti-infective drugs, antipyretic and analgesic drugs, vitamin drugs and drugs for the central nervous system. DMC is mainly used for the synthesis of ciprofloxacin, norfloxacin (norfloxacin), piperic acid, ciprofloxacin lactate and other raw materials, mainly used as methylation agent.

5、Replacing MTBE as gasoline additive to improve octane value of gasoline (this use is mainly in China)

6、Lithium battery electrolyte
Lithium battery electrolyte is mainly composed of organic solvents, such as propylene carbonate, (vinyl carbonate), (diethyl carbonate), (ethyl methyl carbonate).

7、Developer
Tetramethyl alcohol amine can be produced by dimethyl carbonate. P type photoresist developer which is widely used as photoresist developer in large scale advanced integrated circuit lithography.

Linyi Evergreen Chemical Co., Ltd., founded in October 2013, is a wholly-owned subsidiary of ECHEMI group, covering an area of 85 Acres, with a registered capital of 30.5 million yuan, the main production and operation of propylene oxide and other products, propylene carbonate, propylene glycol, dimethyl carbonate and so on.

Evergreen is located in Shandong Linyi Lingang economic development zone, 30 km from lanshan port, 50 km from rizhao port, 100 km from lianyungang port, 120 km from huangdao port. In 2018, Evergreen had passed the work review of enterprise safety production standardization, safety risk hierarchical management and control, and the construction of double prevention system of accident hidden danger investigation and treatment.
