production method | 1molN,N-dimethylcocamidopropylamine, appropriate amount of water (as solvent), an appropriate amount of the chelating agent is put into the reaction kettle, and the temperature is raised to 55 to 60 ° C. With stirring, and hydrogen peroxide is added dropwise at this temperature. After the dropwise addition is completed, the temperature is raised to 70~75 ℃, and the reaction time is usually 4~12H until the end of the reaction. After the reaction is completed, the product is packaged by cooling and discharging. |
