Usage
- Serves as a high-performance "universal solvent" to dissolve synthetic fiber raw materials (e.g., polyacrylonitrile for acrylic fibers), plastic resins (e.g., PVC), and pharmaceutical intermediates.
- Aids in organic synthesis reactions (e.g., nucleophilic substitution) and pharmaceutical purification (e.g., extraction, recrystallization).
- Used in coatings/inks to dissolve resins and colorants, improving coating adhesion and ink spreadability.
- Acts as a reaction reagent or catalyst carrier in certain chemical processes (e.g., formylation reactions).
