3- (N-Ethyl-3-Methylanilino) Propanesulfonic Acid Sodium Salt
To prepare sodium 3 - (N - ethyl - 3 - methylanilino) propanesulfonate, the following method can be followed.
First take an appropriate amount of 3 - methylaniline, place it in a suitable reaction vessel with bromoethane, and add an appropriate amount of basic catalyst, such as potassium carbonate. When controlling the reaction temperature within a certain range, such as 50 - 70 ° C, and the number of reactions, this step aims to introduce ethyl groups into the nitrogen atom of 3 - methylaniline to generate N - ethyl - 3 - methylaniline.
After the reaction is completed, the reaction system is cooled, extracted with an appropriate organic solvent, such as dichloromethane, separated, dried, and distilled to obtain pure N-ethyl-3-methylaniline.
Then, take this product and sodium 3-chloropropanesulfonate in a certain molar ratio, such as 1:1.2, add it to another reaction vessel, add an appropriate amount of phase transfer catalyst, such as tetrabutylammonium bromide, and react at an appropriate temperature, such as 80-100 ° C. The purpose of this reaction is to substitution the amino group of N-ethyl-3-methylaniline with the chlorine atom of sodium 3-chloropropanesulfonate by nucleophilic substitution, thereby generating the target product 3- (N-ethyl-3-methylaniline) propanesulfonate sodium salt.
After the reaction is completed, the reaction solution is cooled and recrystallized with an appropriate solvent, such as ethanol-water mixed solvent. After multiple crystallization, dry to obtain a pure 3- (N-ethyl-3-methylanilino) propanesulfonate sodium salt product. The whole process requires strict control of the reaction conditions to ensure the smooth progress of the reaction and the purity of the product.
3- (N-Ethyl-3-Methylanilino) Propanesulfonic Acid Sodium Salt
3 - (N-ethyl-3-methylanilinyl) propane sulfonate sodium salt, this is a fine chemical, when storing, pay attention to the following things:
