Daily ChemicalsDodecyl Dimethyl Benzyl Ammonium Chloride CAS #122-19-0
Stearic dimethyl benzyl ammonium chloride is a white solid or viscous liquid with slight odor.
Synthesis of benzyl dimethyl stearyl ammonium chloride: put 450kg dimethyl octadecylamine into a reactor, heat it to 80~85 ℃, and slowly add 180kg benzyl chloride within 1.5~2h under stirring. The temperature shall be kept at 80~90 ℃ during the dropping process. After dosing, temperature rise to 100~105 ℃, keep the reaction for several hours, and take samples to determine the pH value. When the pH value of 1% aqueous solution reaches 6~6.5, the reaction is completed. Lower the temperature to 60 ℃ and discharge to obtain benzyl dimethyl stearyl ammonium chloride.
