| Triethanolamine 1. English name: Triethanolamine 2. CAS: 102-71-6 3. Molecular formula: C6H15O3N Structural formula: N (CH2CH2OH) 3 4. Relative molecular weight: 149.19 Density: 1.1242 5. Melting point: 21.2 ℃ 6. Boiling point: 360 ℃ 7. Flash point: 193 ℃ 8. Refractive index: 1.4852 9. Solubility: It has hygroscopicity and can be mixed with water, ethanol, acetone, etc. The solubility in benzene is 4.2% at 25 ℃. 10. Chemical properties: It is alkaline and can absorb CO2 and H2S. Its aqueous solution is alkaline and can react with inorganic or organic acids to form salts. It can also form lipids with higher fatty acids. 11. Purpose: (1) Used as a surfactant, cutting oil, antifreeze, in the metal processing industry, it can be used to prepare corrosion inhibitors, protect metal surfaces, and prevent oxidation. (2) In the electroplating industry, it can replace sodium cyanide or use micro cyanide electroplating, which is called micro cyanide or non cyanide non-toxic electroplating. The internal quality of the plated parts is completely comparable to that of cyanide plated parts. (3) The main raw materials for cement grinding aids (accounting for about 75% of the total formula of grinding aids) can increase cement production by 10% -20% by adding grinding aids. (4) Directly adding cement clinker as grinding aid (with a ratio of about one in ten thousand) and ball milling after mixing can not only increase cement production, but also increase fineness, improve quality standards, and reduce energy consumption. (5) Concrete water reducing agent raw materials. (6) Concrete early strength agent raw materials. 12. Other uses: (1) Detergent raw materials; (2) Beauty product raw materials; (3) Skincare products, cosmetic ingredients. Triethanolamine Triethanolamine also acts as a neutralizing agent in cosmetics, which can neutralize CP-940, thereby achieving thickening and moisturizing effects.
