BEST QUALITY/Dimethyl carbonate/DMC/616-38-6 CAS NO.616-38-6

with big and strong MFG

There are three main types of dimethyl carbonate: industrial grade, medical grade and battery grade. Industrial grade dimethyl carbonate occupies more than half of the market share. These produced dimethyl carbonate are mainly used in the production of polycarbonate and electrolyte solvents. The Chemicalbook production of dimethyl carbonate in foreign countries mainly consists of gas phase oxidative carbonylation and liquid phase oxidative carbonylation. The main domestic processes are PO transesterification, two-step urea, one-step urea, coal to ethylene glycol, methanol carbonyl oxidation and EO transesterification.

Dimethyl carbonate (DMC) has a unique molecular structure (CH3O-CO-OCH3), which contains carbonyl, methyl, methoxyl and carbonyl methoxyl in its molecular structure, so it can be widely used in organic Chemicalbook synthesis reactions such as carbonylation, methylation, methoxylation and carbonyl methylation, so it has a very wide range of uses. Mainly used as carbonylation and methylation reagents, gasoline additives, synthetic polycarbonate (PC) raw materials, etc. The large-scale production of DMC was developed along with the non-phosgene synthesis process of polycarbonate.

Dimethyl carbonate can replace traditional toxic raw materials such as phosgene, dimethyl sulfate and methyl chloride. It can be used for non-phosgene synthesis of polycarbonate, diphenyl carbonate, isocyanate and allyl diethylene glycol carbonate; Used for the synthesis of various carbamate pesticides, such as ceverine, etc. Organic synthesis intermediates Chemicalbook, such as anisole, dimethyl ether, alkyl arylamine, symmetric diaminourea, hydrazyl formate, etc. In pharmaceutical industry, it can be used to produce aminoxazolidone, ciprofloxacin, β -ketone carboxylic acid ester pharmaceutical intermediates, etc. In addition, it can also be used as gasoline, diesel additives, refrigerating machine oil and solvent.
