Monoisopropanolamine MIPA: Performance Characteristics, Application Areas, and Selection Guide

1. Product Overview

Monoisopropanolamine (MIPA, CAS No. 78-96-6), also known as 1-amino-2-propanol or isopropanolamine, is an organic amine compound with the molecular formula C₃H₉NO and a molecular weight of 75.11. The product appears as a colorless to light yellow transparent liquid at room temperature. It is optically active, soluble in water and ethanol, and its aqueous solution is alkaline.

MIPA is an important variety in the isopropanolamine series, which also includes diisopropanolamine and triisopropanolamine. MIPA offers relatively low production costs and certain cost-effectiveness advantages. Its molecule contains two reactive functional groups: an amino group and a hydroxyl group. It can react with acids to form esters and with acid halides to form amide compounds. This structural feature provides it with a relatively wide range of application values.

2. Typical Technical Specifications

Note: The above data represent typical specifications. Values may vary by grade or batch. Please refer to the product test report for specific parameters.

3. Key Performance Characteristics

3.1 Surface Activity and Emulsifying Properties

MIPA exhibits good surface activity. When reacted with fatty acids or alkylbenzene sulfonic acids, it produces fatty acid isopropanolamides and alcohol amine salts of alkylbenzene sulfonic acids, which have strong foaming ability and foam stability. This property gives it application value in detergents, cosmetics, and other daily chemical products.

3.2 Alkaline Neutralization Performance

MIPA aqueous solution is alkaline and can neutralize acidic substances. Its neutralization products with oleic acid or lauric acid are important raw materials for detergents and cosmetics. Due to its alkaline nature, it can also be used as an absorbent for acidic gases.

3.3 Retarding and Strengthening Effects

In concrete systems, MIPA has a certain retarding effect. Studies indicate that MIPA alone dissolved in water can serve as a concrete retarder while also providing some strengthening effects. In concrete strength enhancer formulations, MIPA is often used as a component of isopropanolamine-based compound formulations.

3.4 Hygroscopic Properties

MIPA has hygroscopic properties and can be used as a refining agent, antistatic agent, and fiber wetting agent in the fiber industry.

4. Main Application Areas

4.1 Surfactants and Daily Chemicals

MIPA is an important raw material for surfactant synthesis, with main applications including:

• Detergents: Reacts with fatty acids to produce fatty acid isopropanolamides for synthetic detergent formulations

• Cosmetics: Neutralization products with oleic acid or lauric acid are used in cosmetics and soap production

• Emulsifiers and Plasticizers: Its organic acid esters can be used as emulsifiers, plasticizers, and solvents

4.2 Fiber Industry

In the fiber industry, MIPA can be used as a refining agent, antistatic agent, dyeing auxiliary, and fiber wetting agent. Its hygroscopic and surface-active properties provide application value in textile processing.

4.3 Concrete Admixtures

MIPA has multiple uses in the concrete admixture field:

• Retarder: Can be used to formulate retarding air-entraining agents. Studies show that MIPA compounded with air-entraining agents can produce retarding air-entraining agents that help improve workability, freeze-thaw resistance, and durability when added to concrete

• Concrete Strength Enhancer: Used as a component of isopropanolamine-based compound formulations

• Cement Grinding Aid: Can be used as a grinding aid component during cement grinding

4.4 Lubricating Oils and Cutting Oils

The phosphates and nitrites of MIPA can be used as antioxidants in lubricating oils and cutting oils.

4.5 Other Industrial Applications

• Solvents: Used as a solvent in various applications

• Pharmaceutical Intermediates: Can be used in pharmaceutical synthesis

• Electroplating Cleaning: Can be used in electroplating cleaning processes

5. Usage Recommendations and Considerations

5.1 Storage Conditions

The product should be stored in sealed containers in a cool, dry, and well-ventilated area, away from acids, oxidizing agents, and other incompatible materials. Storage temperatures should be kept within appropriate ranges.

5.2 Safety Precautions

MIPA is alkaline in nature. Operators are advised to wear protective gloves and safety goggles and avoid contact with skin and eyes.

5.3 Product Selection

MIPA is available in industrial grade and various purity specifications. Industrial applications such as surfactant synthesis and concrete admixtures can use industrial grade products. For research or pharmaceutical applications requiring higher purity, distilled products with content up to 97%–99% are recommended.

6. How to Choose Monoisopropanolamine Products?

When selecting MIPA products, consider the following aspects:

1. Content
Content is a key indicator of product quality. Industrial grade products typically have content ≥80%–85%, while high-quality products can have content above 98%. The appropriate purity grade should be selected based on the intended use.

2. Appearance and Color
Quality products appear as colorless to light yellow transparent liquids. Darker color may indicate insufficient purity or product degradation.

3. Packaging
Common packaging includes 200 kg per drum. Packaging specifications can be selected based on actual usage requirements.

4. Supplier Qualifications
Choose suppliers that can provide product test reports, stable supply capability, and technical support.
