Dodecyl trimethyl ammonium chloride of the effective content of 49% ~ 52%, the appearance of thick liquid. Freezing point -12 ~ -9℃. Density 0.892 g/cm3. The HLB value of 17.1. Flash point (open cup) < 27℃. Surface tension (10% aqueous solution) 33×10-3 N/cm.
Dodecyl trimethyl ammonium chloride and water miscibility. Chemically stable. Resistant to heat, light, acid and alkali. It has excellent permeability, emulsification, antistatic and bactericidal ability.
430kg dodecyl dimethyl tertiary amine was put into the reaction kettle, a certain amount of isopropyl alcohol and water were added, and alkali was used as catalyst. After air replacement in the pressure kettle, the temperature was gradually increased and 111kg chloromethane was injected, and the reaction was conducted for 4h under the pressure of 0.2 ~ 0.3mpa. After cooled to normal pressure, get Dodecyl trimethyl ammonium chloride.
Melting point:237 ºC
Chemical property:white solid.
Use:Used as cation surface active agent.
