Application
α-pyrrolidone is an important chemical raw material and high-polarity organic solvent. It is widely used in the pharmaceutical, textile, cosmetic, solvent, electronic cleaning and other industries.
1. As an organic synthetic raw material and intermediate, it is mainly used polyvinylpyrrolidone, piracetam, γ-aminobutyric acid, nylon -4, polyamide fibers etc.
2. As a solvent, it is mainly used in synthetic resins, pesticides, plasticizers, coloring agent, floor polishes, polyhydric alcohols, printing inks, coatings, iodine, electronics cleaning etc.
Packaging
It is packaged with galvanized buckets (net weight: 200KG), paint coated buckets (net weight: 200KG), HDPE buckets (net weight: 200KG), IBC buckets (net weight: 1,000KG), ISOTANK (NW: 20MT) and stainless land tankers (30MT). |
