Diethanolamine

Description

1. Product Overview
Diethanolamine (DEA) is a high-purity organic amine used primarily as a chemical intermediate and pH stabilizer in industrial formulations. Its primary industrial use spans gas treatment (sour gas sweetening), metalworking fluids, and agricultural chemical production. The key value proposition is its exceptional ability to neutralize acidic components while providing stable alkalinity and surface activity. Strategically, DEA is critical for downstream industries requiring consistent performance in gas purification and corrosion control, where formulation failure carries high operational risk.

2. Key Specifications & Technical Characteristics

• Chemical composition: HN(CH₂CH₂OH)₂ – Secondary amine with two hydroxyl groups

• Purity level: ≥99.0% (typical industrial grade); ≤0.5% water, ≤0.3% triethanolamine

• Physical characteristics: Colorless to pale yellow viscous liquid; mild ammonia odor; freezing point ~28°C (82°F); density 1.09 g/mL at 20°C; viscosity ~380 cP at 30°C

• Packaging options: 225 kg net steel drums, 1,100 kg IBC totes, bulk ISO tanks, flexitanks

• Shelf life: 24 months in original sealed containers below 40°C; avoid moisture absorption and CO₂ exposure

3. Core Industrial Applications

• Oil & gas: Sour gas sweetening (removal of H₂S and CO₂) – DEA offers higher selectivity and lower regeneration energy than MEA

• Metalworking fluids: Corrosion inhibitor and pH stabilizer in coolants – outperforms caustic alternatives by reducing skin irritation and extending fluid life

• Agrochemicals: Production of glyphosate, 2,4-D salts, and other herbicides – DEA enables water-soluble, high-load formulations with superior tank-mix stability

• Textiles & detergents: As a cocatalyst in fabric softeners and as an emulsifier – delivers lower foaming than monoethanolamine (MEA)

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified batch-to-batch variance <0.2% via in-line FTIR monitoring

• Supply reliability: Multi-continent production with 99.5% on-time dispatch track record (36-month average)

• Logistics capability: Dedicated heated transport for freeze-protection during winter months

• Price competitiveness: Long-term contracts at ±5% of ICIS benchmark; volume escalators available

• Sustainability: Biodegradable (>60% in 28 days, OECD 301B) and REACH-compliant; no heavy metals or SVHCs

• Technical support: Full SDS, CoA, TDS, and formulation optimization modeling for gas-sweetening efficiency

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk) / 4.4 MT (IBC) / 1.125 MT (drums)

• Loading capacity: 24 MT per 20-foot container (drums/IBCs on pallets); 23 MT per ISO tank container (bulk liquid)
