Isopropanolamine

　　Main Uses

　　Surfactants and Detergents:

　　Used as an emulsifier, foaming agent, and thickener in the preparation of liquid detergents and cosmetics (such as shampoos and body washes) to improve the decontamination ability and stability of the products.

　　Reacts with fatty acids to produce fatty acid isopropanolamides, which are used as softeners and antistatic agents in the textile industry.

　　Metal Processing and Corrosion Protection:

　　Added as a corrosion inhibitor to metal cutting fluids and cooling fluids; it forms a protective film by adsorbing onto the metal surface to prevent corrosion of metals such as steel and copper.

　　Used in metal surface treatment (such as rust removal and phosphating) to adjust the pH value of the solution and enhance the treatment effect.

　　Gas Purification:

　　Used as a substitute for ethanolamine (MEA) for the removal of CO₂ and H₂S from natural gas and syngas; it has high absorption capacity and low regeneration energy consumption, making it suitable for low-temperature desulfurization processes.

　　Pharmaceutical and Pesticide Intermediates:

　　Synthesizes drugs such as antihistamines and local anesthetics, for example, preparing carbamate derivatives through acylation reactions.

　　Used as an intermediate to synthesize herbicides and insecticides, improving the water solubility and biological activity of the pesticides.

　　Other Applications:

　　Used in coatings and inks to adjust pH value and enhance pigment dispersibility;

　　Used as a concrete admixture to improve the frost resistance and strength of concrete;

　　Used to prepare textile auxiliaries to improve the dyeing uniformity of fibers.
