Product Description：

Properties and Usage:

N,N-dimethylacetamide (CAS 127-19-5) is a colorless, transparent, slightly ammoniacal, and highly hygroscopic organic solvent. It is completely miscible with a variety of organic solvents such as water, alcohols, ethers, ketones, and esters, and has excellent solubility and high boiling point.

Application areas:

1. Textile and fiber industry: N,N-dimethylacetamide is a key solvent in the production of aromatic polyamides (such as Kevlar) and polyacrylonitrile (PAN) fibers. Its strong solubility enables the polymer material to be effectively dissolved during the spinning process, ensuring the smooth formation of the fiber.

2. Pharmaceutical industry: In the pharmaceutical field, N,N-dimethylacetamide is used as a reaction medium, especially for complex organic synthesis reactions that require a highly polar environment, such as the synthesis of antibiotics and vitamins. It is also used in the development of pharmaceutical preparations to improve drug solubility and stability.

3. Coatings and coatings: N,N-dimethylacetamide is a raw material for the manufacture of polyurethane, polyamide, and polyester coatings, and is widely used in the construction, automotive, and electronics industries. Its excellent solubility ensures uniform distribution of the coating, smooth coating and strong adhesion, which improves the durability and protective performance of the product.

4. Battery industry: In the production of lithium-ion batteries, N,N-dimethylacetamide as an electrolyte solvent shows good solubility and conductivity, which improves the charging and discharging efficiency and service life of the battery.

5. Organic synthesis: N,N-dimethylacetamide, as a highly polar organic solvent, not only provides the necessary polar environment in a variety of organic reactions such as amidation, hydroxylation, and esterification, but also because of its high boiling point, it is suitable for chemical reactions at high temperatures, thus providing reliable guarantees for complex synthesis processes.

6. Membrane separation technology: N,N-dimethylacetamide is used to manufacture reverse osmosis membranes and hollow fiber membranes, which play an important role in water treatment, gas separation, and hemodialysis. Its solubility helps to improve the separation efficiency and durability of membrane materials.
