Main applications of monoethanolamine

(1) Gas purification: Absorb carbon dioxide and hydrogen sulfide from the gas.

(2) Solvent: Gas chromatographic stationary liquid (the highest use temperature is 50℃, the solvent is ether), used to separate low-carbon alcohols, pyridine and its derivatives.

(3) Pharmacy: synthetic bactericide, antidiarrheal agent.

(4) Printing and dyeing: synthetic high-grade dyes (condensation turquoise blue 13G).

(5) Textile: used as fluorescent whitening agent, antistatic agent, mothproofing agent and detergent.

The main application of diethanolamine

Used as a raw material for corrosion inhibitors in the pharmaceutical industry, as a crosslinking agent in the production of high resilience polyurethane foam; mixed with triethanolamine as a decaking agent for aircraft engine pistons; reacted with fatty acids to produce alkyl alcohol amides; also used in organic synthesis Raw materials, raw materials for the production of surfactants and acid gas absorbents. Used as a thickener and foam modifier in shampoos and light detergents, as an intermediate in the organic synthesis industry, as a solvent in the pharmaceutical industry, in the washing industry, cosmetics industry, agriculture, construction and There are larger uses in the metal industry.

The main application of triethanolamine

Used as a clean liquid for removing carbon dioxide or hydrogen sulfide in gas. The esters formed by triethanolamine and higher fatty acids are widely used as detergents, emulsifiers, humectants and lubricants, and are also used to formulate cosmetic balsams. Triethanolamine is also used as preservative and waterproofing agent, analytical reagent and solvent. Used as an activator in the polymerization of nitrile rubber, it can also be used as an emulsifier and stabilizer for oils and waxes, and a softener for textiles under acidic conditions. It is one of the components of synthetic fiber spinning finishes such as polyester. Used in metal cutting, cooling, rust prevention in metal processing, acid-base neutralizer in cosmetics industry, emulsifier, grinding aid in cement, early strength agent in concrete construction; curing agent in ink industry; also Used in surfactants, rust inhibitors, complexing agents in electroplating, pH regulators and acid gas absorbents.
