Dimethylacetamide (DMAC) Product Description

 

【Product Introduction】

Dimethylacetamide, with the chemical formula CH3C(O)N(CH3)2, referred to as DMAC or DMA, is a highly polar non-protonated solvent. DMAC is a colorless, transparent liquid with a slight ammonia smell. It can dissolve a variety of compounds, including water, aromatic compounds, esters, ketones, alcohols, etc., and can activate compound molecules.

 

 

【Product Features】

High Chemical Stability

Dimethylacetamide has a stable chemical structure under common reaction conditions of -20℃ to 150℃ and pH 4-10. The carbonyl and methyl groups in the molecule work together, the configuration is stable, and it is not easy to react with other substances. It can stably act as a medium for complex chemical reactions.

 

Good Thermal Stability

Dimethylacetamide has a boiling point of 166℃ and is not easy to volatilize and decompose at high temperatures.

 

 

【Product Application】

Pharmaceutical Industry

In the pharmaceutical industry, dimethylacetamide is mainly used as a solvent and reaction medium to promote the synthesis and separation of drugs. It is widely used as an important raw material for drugs such as amoxicillin and cephalosporins, and is also used as a solvent or catalyst in many pharmaceutical production processes.

 

Plastic And Fiber Industry

In the plastic industry, dimethylacetamide is mainly used in the production of heat-resistant synthetic fibers and plastic films.

 

Petroleum Processing Industry

In the petroleum processing industry, dimethylacetamide is used as an extraction distillation solvent to efficiently separate important compounds such as styrene from the C8 fraction.

 

Chemical Synthesis And Catalysts

In the field of chemical synthesis, dimethylacetamide is an important organic synthesis solvent and catalyst. It can accelerate reactions such as cyclization, halogenation, cyanation, alkylation and dehydrogenation, and is widely used in the manufacture of polymer resins, such as the synthesis of polyimide resins. In addition, dimethylacetamide can also be used as an intermediate in the reaction and participate in the synthesis process of various organic compounds.
