Product Description
Acetic Anhydride | Premium Acetylating Agent
Product Overview
Acetic Anhydride is a clear, colorless, highly reactive liquid with a strongly pungent odor. As one of the most widely consumed and economically significant organic anhydrides, it serves as the ultimate acetylating agent in the global chemical industry. It is fundamentally critical to the mass production of essential pharmaceuticals, advanced cellulose polymers, and specialized agrochemicals.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply bulk volumes of High-Purity Acetic Anhydride (≥ 99.5%) to multinational pharmaceutical corporations and polymer gigafactories. Operating strictly under Class 8 / 3 Dangerous Goods protocols and fully compliant with international precursor chemical regulations, our robust supply chain ensures your continuous manufacturing processes never face a shortage.
Technical Specifications (COA)
For high-yield API synthesis and optical-grade cellulose acetate, limiting free acetic acid is essential. Typical specifications:
| Purity (Acetic Anhydride) | ≥ 99.5% |
|---|---|
| Acetic Acid | ≤ 0.5% |
| Color (Pt-Co) | ≤ 10 |
| Heavy Metals (as Pb) | ≤ 2 ppm |
| Residue on Evaporation | ≤ 0.003% |
Key Applications
- Pharmaceutical Synthesis: The primary acetylating agent used in the massive-scale synthesis of everyday essential drugs, most notably Aspirin and Paracetamol.
- Cellulose Acetate Production: Reacted with cellulose to produce cellulose acetate, extruded into films for LCD polarizer displays and tow for cigarette filters.
- Agrochemicals: A vital intermediate in the formulation of specialized herbicides and fungicides.
- Modified Starches: Used to produce acetylated starches, enhancing stability and texture for the food industry.
📜 Export Compliance & Precursor Control
Due to its potential for misuse in illicit drug manufacturing, Acetic Anhydride is a globally monitored precursor chemical. Exporting this material requires strict adherence to international non-proliferation frameworks. All prospective buyers MUST possess a valid chemical import license from their national government and provide a certified End-User Certificate (EUC). Yinglang Chemical’s dedicated compliance team will assist qualified industrial buyers in navigating the legal export process seamlessly.
Bulk Liquid DG Packaging Options
Because Acetic Anhydride reacts violently with moisture, we utilize highly secure packaging for ocean transit:
- ISO TANKS (20+ MT) (Highly recommended for massive industrial procurement).
- 1000 KG IBC Totes.
- 200 KG / 220 KG UN-approved HDPE drums or PE-lined steel drums.
⚠️ Safety & Transport Information (Class 8 / 3 DG)
- Transport Classification: Classified as Class 8 (Corrosive) with Subsidiary Risk 3 (Flammable Liquid).
- UN Number: UN 1715 | Packing Group: II
- Handling Precautions: DANGER. Flammable liquid and vapor. Causes severe skin burns. Reacts violently with water. Operators MUST wear full acid-resistant gear and handle in explosion-proof environments. Store strictly away from water and bases.
