Dimethyl carbonate, also known as methyl carbonate, is a colorless transparent liquid with a relative molecular weight of 90.08, a relative density of 1.0694, a melting point of 2-4 ℃, a boiling point of 90-91 ℃, 42 ℃ (1.60 × 104Pa), flash point 21.7 ℃, 16.7 ℃ (closed), refractive index 1.3687. Soluble in water (13.9 at 20 ℃), chloroform, toluene, and easily soluble in ethanol, inorganic acids, and alkali solutions. With strong chemical reactivity, it can provide methylation, carbonylation, and acylation groups to replace environmental pollutants such as phosgene and dimethyl sulfate, and has received widespread attention. Rat oral LD5013.80ml/kg. Due to its extremely low toxicity, this product is widely used as a pharmaceutical raw material for the production of furazolidone; An intermediate of pesticides, used to prepare the insecticide carbaryl (also known as carbaryl) and the acaricide furan for the control of diseases and pests in vegetables, fruit trees, and cotton; Preparation of diphenyl phosphate as a raw material for polycarbonate, which is widely used as engineering plastics and optical materials; Used as a raw material for isocyanates, from which polyurethane can be produced; Used for the production of thermosetting tree chemical book allyl diethylene glycol carbonates, used as optical materials; Used as a raw material for the production of p-diaminourea, which is a boiler cleaning agent; Used as a raw material for long chain alkyl carbonates and tetramethylammonium hydroxide; Raw materials for the preparation of anisole, spices, N-methylcarbazole, and metasemicarbazide; It can be used as a gasoline additive to increase the octane number; It is also used as an intermediate in other organic synthesis, methylation agent, and carbonylation. This product can be prepared by reacting methanol and phosgene to produce methyl chloroformate, which is further reacted with methanol; It can also be obtained by vapor phase (or liquid phase) carbonylation and oxidation of methanol and carbon monoxide using a cuprous chloride catalyst at 100 to 140 ℃ and 2.0 to 2.5 MPa; Ethylene oxide can also be used as a raw material to react with carbon dioxide to generate vinyl carbonate, which is then transesterified with methanol to obtain; Using methyl nitrite as a raw material, it can also be prepared by reacting with carbon monoxide under the action of platinum and palladium catalysts. Dimethyl carbonate, as an important chemical product in the 21st century, is currently receiving increasing attention from countries around the world, and has gradually formed a new cornerstone of organic synthesis with DMC as the core.
