Embodiment

[0011] The synthetic method of the benzyl ammonium benzoate amide of the present embodiment may further comprise the steps:

[0012] (1) Add the benzyl halide to the reactor containing the raw material lidocaine under stirring and at a certain temperature, the reaction temperature is from room temperature to 130°C, and the ratio of lidocaine and benzyl halide is 1:1;

[0013] (2) After the reaction is complete, add solvent and metal hydroxide;

[0014] (3) Add benzoic acid, and after the reaction finishes, the generated benzyl ammonium amide is filtered, washed, concentrated, and washed to obtain the product benzyl ammonium amide.

[0015] The synthesis method of benzyl ammonium benzoate amide does not require cumbersome post-reaction treatment, greatly improves the product performance, is environmentally friendly and has no pollution, the process flow is easy to implement, the production cost is low, the synthesis yield is high, and the industrialization of the product is bet...

Abstract

The present invention discloses a denatonium benzoate synthesis method, which is characterized in that lidocaine, benzyl halide, a metal hydroxide and benzoic acid are sequentially added to a reactor to produce denatonium benzoate through a one-pot method or two-pot method, and lidocaine, benzyl halide and benzoate are sequentially added to a reactor to produce denatonium benzoate through a one-pot method or two-pot method. With the method of the present invention, the defect that the post-treatment is performed after each step of the reaction is eliminated so as to simplify the production process and reduce the production cost, and the raw material ratio is reasonable, and the product quality can be improved.
