Glacial acetic acid 99.8%

Description

1. Product Overview

Glacial acetic acid (99.8%) is a colorless, hygroscopic organic acid with a pungent odor, freeze-resistant for controlled handling. It serves as a cornerstone intermediate for vinyl acetate monomer (VAM), purified terephthalic acid (PTA), acetate esters, and pharmaceutical synthesis. The key value proposition lies in its ultra-low water content, which prevents unwanted side reactions and maximizes yield in anhydrous processes. Strategically, it is indispensable for downstream chemical manufacturing, directly impacting production economics in Asia, Europe, and the Americas.

2. Key Specifications & Technical Characteristics

• Chemical composition: Acetic acid (CH₃COOH) ≥ 99.8% by mass; water ≤ 0.15%; acetaldehyde ≤ 0.05%; formic acid ≤ 0.05%

• Purity grade: 99.8% – industrial synthesis grade, suitable for high-precision reactions

• Physical characteristics:

  • Form: Clear, colorless liquid

  • Freezing point: 16.6°C (solidifies below this; re-liquefies with gentle warming)

  • Boiling point: 117–118°C

  • Density: 1.049 g/cm³ at 20°C

• Packaging options:

  • 30 kg HDPE carboys

  • 200 kg UN-certified steel drums

  • 1,000 kg IBC totes

  • Bulk isotanks (20,000–24,000 L)

• Shelf life: 24 months in original sealed container, stored between 15–25°C away from oxidizers

3. Core Industrial Applications

• Chemicals & polymers: Production of VAM (adhesives, paints, coatings), PTA (polyester fibers & bottles), and acetate esters (solvents for inks, coatings)

• Pharmaceuticals: Synthesis of aspirin, paracetamol, and antibiotic intermediates – 99.8% purity eliminates water-induced hydrolysis, improving API yield by 3–5%

• Textile & printing: Neutralization of alkali residues and pH adjustment in dyeing; outperforms dilute acids due to lower dosage requirement and consistent reaction profiles

• Food & feed preservatives: As precursor for calcium/sodium acetate (mold inhibitors) – lower water content reduces bacterial growth during bulk storage, extending mill-to-plant stability

Cost advantage: 99.8% grade reduces catalyst poisoning and side products, lowering downstream purification costs by up to 12% compared to 99.0% grades.

4. Competitive Advantages

• Quality consistency: Batch-to-batch variation < 0.05% via ISO 9001-certified continuous distillation with real-time GC monitoring

• Supply reliability: Multi-plant production (China, India, USA) with 40,000 MT/month capacity and buffer stock in Rotterdam, Houston, and Shanghai hubs

• Logistics capability: Dedicated fleet of stainless steel isotanks and temperature-managed drums; door-to-door tracking with 48-hour emergency response for spills

• Price competitiveness: Direct from producer via long-term methanol feedstock contracts; spot pricing benchmarked to ICIS, plus volume rebates above 500 MT/quarter

• Sustainability: ≥ 30% bio-based acetic acid available upon request; returnable packaging programs reduce single-use drum waste by 60% for committed buyers

• Technical support: Full Material Safety Data Sheet (MSDS), Certificate of Analysis (CoA) per batch, and on-call process engineering advisory for integration into existing lines
