Manufacturing Process of Diethanolamine: Step-by-Step Overview

Figure: Diethanolamine Manufacturing Flow – Ethylene Oxide and Ammonia undergo ammonolysis in reaction vessels, followed by product separation via controlled distillation, rigorous ISO/QC analysis, and packaging for industrial use. Rapid batch changeover, feedstock traceability, and in-line GC testing are maintained throughout.

Technical Advantages of Leading Diethanolamine Manufacturers

High Purity & Low Color: Advanced fractional distillation and closed-loop ammonolysis ensure DEA purity ≥99.5% with APHA color ≤30, key for surfactant and pesticide intermediate production.
Material Traceability: PP/PE lined steel drums/totes (UN-rated) and in-tank RFID tracking enable full backward traceability across supply chains, meeting FDA and EU REACH standards.
Process Automation: DCS/PLC digital controls and automated GC feedback minimize batch-to-batch variation, boosting consistency for high-spec applications (polyurethane catalysts, gas sweetening units).
Certifications: Most premium diethanolamine manufacturers (including DS Biochemical) maintain ISO 9001:2015 and SGS, often supported by third-party compliance audits for food-contact indirect applications.
Environmental Safety: Waste heat recovery and ammonia/EO abatement skids lower GHG emissions up to 19% per ton output (reference: Chemical Engineering Progress, 2023).

Customizable Solutions by Diethanolamine Supplier

Whether for complex amine blend gas treaters, specialty surfactant R&D, or advanced polycarbonate chain extenders, leading diethanolamine supplier companies offer bespoke DEA formulations:

Aminopropyl diethanolamine grades for corrosion inhibitors and polymer intermediates
Low-water DEA (<0.1%) for semiconductor and electronics process chemicals
High-permittivity variants for polyurethane catalyst/dye manufacture
Bulk, ISO tank, 500kg tote, or 200L drum supply with dedicated lot numbers
Formulation support, REACH/OSHA/FDA documentation, COA and MSDS on batch
Colorless & odor-stabilized options for personal care/toiletries

Key Applications & Industrial Case Studies

Gas Sweetening (Amine Treatment): DEA is widely blended with MEA/MDEA in CO₂ and H₂S removal units for LNG, petrochemical, and refinery streams. Compared to simpler amines, DEA offers a balance of absorption efficiency, solvent longevity, and corrosion rate (per ACS Ind Eng Chem Res 2021).
Detergents & Surfactants: Linear alkylbenzene sulfonate DEA salts and coconut fatty acid DEA amides provide excellent foam stability/cleaning for homecare and I&I detergents—DEA-based amides outperform monoethanolamine/glycerol blends in oil emulsion stability and viscosity control.
Personal Care/Cosmetics: DEA neutralizes fatty acids in shampoos and creams, greatly enhancing emulsion uniformity. Top-tier diethanolamine manufacturers deliver colorless, low-odor grades for global direct-touch compliance (see FDA Safety/Cosmetic Use).
Textiles & Leather: DEA-based lubricants/sIz.ing agents are prized for their biodegradability and anti-static properties in high-speed looms and tanning drums.
Metalworking & Corrosion Inhibition: DEA is an efficient steel corrosion inhibitor in water-based coolants and closed heating/cooling loops, with field tests showing up to 37% service life extension vs. monoamines.

Expert FAQ: Diethanolamine Procurement & Technical Topics

Q1. What is the typical shelf life and proper storage condition of DEA?

DEA is stable for 12–18 months in sealed container111s at 5–25°C, protected from sunlight and humidity. Contact with copper, zinc, or brass must be avoided to prevent degradation.

Q2. Which international chemical and packaging standards cover DEA?

DEA is regulated under ISO 9001:2015, ASTM D2074/D1209 (testing), UN (hazard packaging), REACH (EU), OSHA (US). Drums/totes comply with UN2014 and DOT49CFR.

Q3. How do aminopropyl diethanolamine and standard DEA differ?

Aminopropyl diethanolamine (APDEA) features a C3-aminopropyl group, enhancing reactivity and anti-corrosion effect for specialty applications, unlike unbranched DEA. APDEA is produced via propyleneamine functionalization.

Q4. Which DEA spec is best for gas treating vs. surfactants?

For gas treating, industrial-grade DEA (≥99.5% purity, low water, low iron/Na) is advised; for surfactants/personal care, cosmetic or technical-grade (colorless, APHA ≤20–30, odor controlled) is preferred.

Q5. What are the key quality control checks before shipment?

Mandatory tests: Purity by GC, water content (KF), amine number, heavy metals (ICP-MS), color (APHA), pH stability. Full COA, MSDS, and lot traceability delivered with each order.

Q6. What is a typical DEA delivery lead time, MOQ, and support level?

Lead time is 7–21 days (spot to bulk), MOQ is usually 1 MT. Technical support includes pre-shipment sample approval, blending and logistics consulting, and post-sale product application guidance.

Q7. Is DEA FDA-approved for direct food or pharma usage?

DEA (CAS 111-42-2) is not FDA-approved for direct food/pharma use but is allowed in indirect uses (e.g., processing aids, adhesives) as per 21 CFR 177.2600. Always verify regulatory scope per geography.
