Main Applications

　　Dissolution and Processing of Polymer Materials

　　As a solvent for high-temperature engineering plastics such as polyimide, polysulfone, and polyphenylene sulfide, it is used to prepare films, fibers, or coatings (e.g., polyimide films for the production of insulating materials in the electronics industry).

　　Dissolving synthetic fibers (such as acrylic fibers) for spinning processes to improve fiber uniformity and mechanical properties.

　　Organic Synthesis and Pharmaceutical Intermediates

　　As a reaction solvent for catalytic reactions, condensation reactions, etc., it is particularly suitable for reactions requiring a polar environment but avoiding proton interference (e.g., Grignard reactions, nucleophilic substitution reactions).

　　In the pharmaceutical field, it is used for the synthesis and purification of antibiotics, hormones, and other drugs, improving reaction efficiency and product purity.

　　Coatings and Inks Industry

　　As a solvent or co-solvent for high-end coatings (such as automotive paints and anti-corrosion paints) and inks, it can dissolve resins and pigments, enhance the leveling and adhesion of coatings, and has a moderate evaporation rate, facilitating application.

　　Other Fields

　　Used in extraction and separation processes, such as extracting aromatic hydrocarbons from petroleum fractions or separating metal ions from organic phases.

　　As a textile auxiliary for fiber dyeing and finishing, improving the solubility of dyes and dye uptake rates.
