Isopropanolamine Series Product Introduction

1. Product Overview

Isopropanolamines are a class of organic compounds containing both amino and hydroxyl functional groups, belonging to the alkanolamine family. Due to the presence of both the basicity of the amine group and the hydrophilicity of the hydroxyl group, isopropanolamines exhibit unique reactivity and can participate in various chemical reactions including esterification, amidation, and salt formation.

Isopropanolamine series products are primarily produced through the reaction of propylene oxide with ammonia, forming different homologs depending on the number of hydrogen atoms replaced by isopropanol groups in the ammonia molecule. These products are characterized by low toxicity and environmental friendliness, and are widely used in surfactants, pharmaceutical and pesticide intermediates, metalworking fluids, gas treatment, and cement additives.

2. Product Classification

Isopropanolamine series products are divided into five main types based on molecular structure:

1. Monoisopropanolamine (MIPA)

2. Diisopropanolamine (DIPA)

3. Triisopropanolamine (TIPA)

4. Diethanolisopropanolamine (DEIPA)

5. Ethanol Diisopropanolamine (EDIPA)

3. Main Applications

1. Cement Grinding Aids and Additives

TIPA, DEIPA, and EDIPA are important raw materials for cement grinding aids, playing significant roles in cement production:

• TIPA: Primarily used to improve the late-strength of finished cement and enhance cement fluidity

• DEIPA: Capable of improving both early-strength and late-strength of cement, serving as a novel high-efficiency grinding aid raw material

• EDIPA: Helps reduce energy consumption in cement production, increase output per unit time, and improve overall cement performance

When used in cement grinding aids, triisopropanolamine does not cause rapid cement setting due to its weak basicity, while improving cement fluidity and late-strength. Research shows that DEIPA can be used in combination with triethanolamine and sodium formate to significantly enhance both early and late strength of cement.

2. Gas Treatment

MIPA and DIPA have important applications in gas purification:

• DIPA: Widely used in refinery and natural gas desulfurization processes. Due to its optimal balance between absorption selectivity, regeneration energy consumption, and degradation rate, it is known as the "gold standard" of desulfurization agents

• MIPA: Suitable for applications requiring rapid reaction and deep removal of acid gases

3. Surfactants and Personal Care Products

MIPA and DIPA are important raw materials for surfactant production:

• React with fatty acids to form fatty acid isopropanolamides, which exhibit excellent foaming properties, foam stability, and oil dissolution capabilities

• Alkylolamides produced from DIPA and lauric acid serve as important thickeners and foam stabilizers in shampoos and body washes

4. Pharmaceutical and Pesticide Intermediates

MIPA, with its high reactivity, can be used to synthesize various pharmaceutical and pesticide active molecules.

5. Metalworking Fluids

MIPA and DIPA are used as neutralizers and corrosion inhibitors in metalworking fluids:

• Provide good pH adjustment capabilities

• Organic acid esters formed from reactions with fatty acids can be used as antioxidants in lubricating oils and cutting oils

6. Other Applications

• Polyurethane Catalysts: TIPA can serve as a mild reaction catalyst for producing flexible foams

• Coatings and Paints: Used to adjust pH and stability of coating systems

• Textile Auxiliaries: Used as scouring agents, antistatic agents, dyeing aids, and fiber wetting agents in the textile industry

• Cosmetic Ingredients: Reaction products with thioglycolic acid can be used in cosmetic formulations

• Detergents: Neutralization products with oleic acid or lauric acid are important raw materials for detergents and cosmetics

4. Packaging and Storage

200kg/drum or IBC tank. Keep cool, ventilated; away from ignition sources.

Storage Precautions:

• Store in a cool, well-ventilated, dry warehouse away from direct sunlight

• Store separately from strong oxidizing agents and strong acids

• Keep containers sealed to prevent moisture absorption and contamination
