Method for preparing alkylbenzyl morpholine quaternary ammonium salt

摘要

The method for preparing morpholine quaternary ammonium salts by adding and reacting alkyl morpholine and benzyl halide in the presence of a solvent and an alkali catalyst has a strong bactericidal effect on microorganisms such as bacteria, fungi and yeast, and has a low foaming property and low toxicity. The N-alkylbenzyl morpholine quaternary ammonium salt of 1 can be prepared in high purity and high yield in a short time at low temperature.;[Formula 1];In Formula 1, X is a halogen atom, R ₁ is a linear or pulverized alkyl radical having 8 to 18 carbon atoms, and R ₂ is selected from the group consisting of hydrogen, a halogen atom, a hydroxyl group and an alkyl radical having 1 to 4 carbon atoms. .
