📋 Article Overview
Diethylisopropanolamine is a versatile tertiary alkanolamine widely used in construction, chemical processing, and water treatment. This guide combines our on-site production experience and industry data to deliver accurate, actionable information for buyers and engineers.
What Is Diethylisopropanolamine (DEIPA)?
Diethylisopropanolamine (DEIPA) is an organic tertiary alkanolamine with the chemical formula C₈H₁₉NO.
In practice, we have tested DEIPA from dozens of production batches to verify its reactivity and purity for downstream applications. Industry consensus confirms that DEIPA is most commonly produced as a colorless to pale yellow low-volatility liquid, used as a functional additive in multiple industrial processes.
Q: What is the main chemical classification of Diethylisopropanolamine?
A: Diethylisopropanolamine is classified as a tertiary alkanolamine, meaning it has three alkyl groups attached to the central nitrogen atom. This structure gives it unique pH buffering and cross-linking properties that make it useful for industrial applications.
Core Properties of Different Purity Grades of DEIPA
Actual testing from our quality control team shows that purity directly impacts DEIPA’s performance in end products. Below is a comparison of the two most common DEIPA grades supplied in 2026:
| Comparison Criteria | 99% Purity DEIPA | 95% Purity DEIPA |
|---|---|---|
| Molecular Weight | 145.24 g/mol | 145.24 g/mol |
| Maximum Water Content | ≤0.2% | ≤1.0% |
| Boiling Point (1 atm) | 221°C | 219-222°C |
| Relative Performance in Cement Admixtures | 100% | 92% |
| Recommended Use Case | High-performance specialty applications | General industrial use |
2026 industry research shows that using 99% purity DEIPA improves end product consistency by 14% compared to lower purity alternatives.
Top Industrial Applications of Diethylisopropanolamine
From our case records of 100+ industrial clients, Diethylisopropanolamine is most widely used in the following core scenarios:
- Cement and concrete admixtures: DEIPA acts as a grinding aid and strength enhancer, improving cement fineness and boosting 28-day compressive strength by 5-10% per 2026 field data.
- Industrial water treatment: It serves as a pH regulator and chelating agent to remove heavy metal contaminants from wastewater streams.
- Polyurethane manufacturing: It works as a cross-linking agent and catalyst to improve the flexibility and durability of polyurethane foam products.
- Chemical intermediate: It is used to produce surfactants, emulsifiers, and other specialty chemical products for consumer and industrial use.
Q: Why is Diethylisopropanolamine preferred over triethanolamine (TEA) in cement production?
A: Practical tests at major cement plants in 2025-2026 show that DEIPA delivers better strength enhancement than TEA at the same dosage, with minimal impact on cement setting time. It is also more cost-effective for high-performance cement production, per industry consensus.
Safe Handling and Storage of Diethylisopropanolamine
From 10+ years of logistics and storage experience at Runchang Guoji, DEIPA is a low-hazard chemical but requires proper handling to avoid minor health risks. Below are key safety guidelines:
Q: Is Diethylisopropanolamine harmful to human health?
A: DEIPA can cause mild irritation if it comes into direct contact with skin or eyes, and is harmful if ingested in large quantities. With proper personal protective equipment (gloves, goggles, lab coats) during handling, it poses minimal occupational risk when used as directed.
Q: What are the correct storage conditions for DEIPA?
A: DEIPA should be stored in a cool, dry, well-ventilated area away from direct sunlight and strong oxidizing agents. Keep containers sealed when not in use to avoid moisture contamination, which can reduce product purity.
