Add equal amounts of o-phenylenediamine and stearyl chloride to a condensation kettle in sequence, stir at 0-5 ℃ for acylation reaction, and the reaction takes place between pH values of 8-9. After the reaction is completed, add the water-based agent toluene, raise the temperature, and continuously steam the azeotrope of the water and toluene under reflux. After a few hours of reaction, check the residual amount of o-phenylenediamine, complete conversion of aniline as the endpoint, press the product into a second condensation kettle, and add benzyl chloride dropwise for alkylation reaction. Finally, fuming sulfuric acid is added for sulfonation neutralization reaction, cooling, crystallization, and drying to obtain the finished product.
This product can be managed according to general industrial chemicals. When using it, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
equimolar o-phenylenediamine and stearoyl chloride were successively added into the condensation kettle, and the acylation reaction was carried out by stirring at 0~5 ℃, and the reaction was carried out at pH 8~9. After the reaction, add the water-carrying agent toluene, heat up, and continuously evaporate the water and the azeotropic liquid of toluene under reflux. After a few hours of reaction, check the residual amount of o-phenylenediamine, take the complete conversion of aniline as the end point, press the product into the second condensation kettle, and drop benzyl chloride for alkylation reaction. Finally, fuming sulfuric acid is added for sulfonation neutralization reaction, cooling, crystallization and drying to obtain the finished product.
