What is the synthesis method of 4-chloro-3-nitrobenzenesulfonic Acid, Sodium Salt?
To prepare 4-chloro-3-nitrobenzene sulfonate sodium salt, you can follow the following method.
First take benzene as the starting material, use chlorine as the reagent, and under the catalysis of ferric chloride, make benzene and chlorine substitution reaction to obtain chlorobenzene. This reaction needs to be controlled at a certain temperature range to make the reaction proceed smoothly, and there are many para-and ortho-substituted products, but the main product is chlorobenzene.
Then, make chlorobenzene react with mixed acid (mixture of nitric acid and sulfuric acid), nitric acid under the action of sulfuric acid produces nitroyl positive ion, which is an electrophilic reagent, and undergoes an electrophilic substitution reaction with chlorobenzene. Nitro is introduced into the ortho-position of chlorob In this step, the reaction conditions need to be precisely controlled. The ratio of sulfuric acid to nitric acid and the reaction temperature all affect the yield and purity of the product.
Then, with o-nitrochlorobenzene as the substrate, the sulfonation reaction is carried out by co-heating with fuming sulfuric acid. The sulfonic acid group (-SO 🥰 H) replaces the hydrogen at a specific position on the benzene ring to obtain 4-chloro-3-nitrobenzene sulfonic acid. In this reaction, factors such as the concentration of fuming sulfuric acid, reaction time and temperature are critical, which affect the location and degree of sulfonic acid group introduction.
Finally, 4-chloro-3-nitrobenzenesulfonic acid is reacted with a base such as sodium hydroxide or sodium carbonate, and the hydrogen of the sulfonic acid group is replaced by sodium ions to obtain 4-chloro-3-nitrobenzenesulfonic acid sodium salt. After the reaction, after crystallization, filtration, washing, drying and other steps, a pure product can be obtained.
After each step of the reaction, it needs to be separated and purified, such as distillation, extraction, recrystallization, etc., to remove impurities and extract the purity of the product, so that the product of each step meets the requirements of the next reaction, so that the sodium salt of 4-chloro-3-nitrobenzenesulfonic acid can be effectively synthesized.
