Triethanolamine, namely tris(2-hydroxyethyl)amine, is an organic compound, which can be regarded as a three-substituted product. Similar to other types of compounds, triethanolamine has properties due to the presence of nitrogen atoms. , capable of reacting to produce salt.
Chinese name: 2,2,2-nitrilotriethanol; aminotriethanol; trihydroxyethylamine; tri(2-hydroxyethyl)amine; trihydroxytriethylamine
English name: Tris(2-Hydroxyethyl)Amine;Triethanolamine(2-Hydroxyethyl)amine;
Chemical formula: (HOCH2CH2)3N

Application
1. Triethanolamine is used as plasticizer, neutralizer, lubricant Additives or preservatives for pharmaceuticals, moisturizers for textiles and cosmetics, and dispersants for dyes and resins. Used as a curing agent for epoxy resin, the reference dosage is 12~15 parts (mass fraction), and the curing condition is 80°C/4H or 120°C/2H. It can also be used as a raw material for synthetic surfactants, detergents, stabilizers, and fabric softeners. In cosmetic formulations, it is used to neutralize with fatty acids to form soap, and to neutralize with sulfated fatty acids to form amine salts. It is used as a cleaning solution for removing acid gases such as hydrogen sulfide and carbon dioxide in waste gas treatment. It can also be used as a vulcanization activator for natural rubber and synthetic rubber, as a polymerization activator for nitrile rubber, and as a lubricating oil and anti-corrosion additive.
2. The long-chain fatty acid salt of triethanolamine is almost neutral and can be used as an emulsifier for oil and wax. Its oleic acid soap can increase the washing ability of gasoline; stearic acid soap is used in fragrance cosmetics. Triethanolamine can be used as a solvent for shellac, dyes, etc. It can also be used in industrial gas purifiers, fiber treatment agents, anti-corrosion additives, plasticizers, humectants, chelating agents, rubber vulcanization accelerators, photographic developer additives, detergents, cement reinforcing agents, anti-carbon additives, etc.
3. As a corrosion inhibitor, triethanolamine is an important corrosion inhibitor component in boiler water treatment, automotive engine cold cutting agent, drilling and cutting oil. It can also be used in surfactants, textile products, waxes, polishing agents, herbicides, petroleum demulsifiers, cosmetics, cement additives, cutting oils, etc.
4. Triethanolamine is used as gas chromatography stationary liquid, metal masking agent, compounding agent, emulsifier, dry cleaning agent, solvent, softener and resin synthesis.
5. Mainly used in the preparation of surfactants, detergents, stabilizers, emulsifiers, and fabric softeners. The addition of triethanolamine to liquid detergents can improve the removal of oily dirt, especially non-polar sebum, and at the same time, the decontamination performance can be improved by increasing the alkalinity. In addition, in liquid detergents, its compatibility is excellent.
6. Triethanolamine and its salt solution are used as additives in the cement grinding process, which can not only prevent the aggregation of powder particles and the effect of air cushion in the grinding process, improve the fluidity and filling density of cement, but also reduce the grinding process. The power consumption of the machine
7. It can complex with zinc in alkaline zincate galvanizing, improve the cathodic polarization of the plating solution, and make the coating crystallize finely. If the content is too high, the deposition rate will be reduced, and the If it is low, the coating will be gray and rough, and the dispersion force will be poor. The general content is 20~30ML/L.. However, the high viscosity of triethanolamine reduces the upper limit of the current density of the plating solution.
