TRIMETHYLOCTADECYLAMMONIUM BROMIDE - Reference Information
| Overview | Decyltrimethylammonium bromide (English name: OctadecylTrimethylAmmoniumBromide, abbreviation: OTAB) is a quaternary ammonium salt antibacterial agent, white powder. OTAB is a cationic surfactant with strong bactericidal and mildew-inhibiting and mothproof properties. It is commonly used as waterproofing agent, retarding agent, petroleum demulsifier and oilfield fungicide. |
| chemical properties | this product is a white or yellowish solid (paste). Freezing point 32 ℃,HLB value 15.8. Soluble in water, good stability, heat resistance, light resistance, strong acid, strong alkali resistance, microbial degradation. |
| Use | See trimethyldecadecyl ammonium chloride. Used as a surfactant Used as a surfactant Applied to catalysts, emulsifiers, disinfectants, germicidal groups, antistatic agents, etc. |
| production method | first add dimethylocepamine to the pressure kettle, then add appropriate amount of water and isopropanol as solvent, and use a small amount of alkali as catalyst. Nitrogen filling replaces the air in the kettle (avoiding side reactions), heats to 120~150 ℃, and slowly passes in methyl bromide (theoretical amount). React at 0.4 ~ 0.5MPa for 2 h, cool, depressurize, and dilute to 50% with water. The discharge packaging is the finished product. |
