What is the production method of 4-Chloroaniline-2-Sulfonic Acid?

The preparation method of 4-chloroaniline-2-sulfonic acid has followed the following methods throughout the ages.
First, 4-chloroaniline is used as the initial material and is obtained by the method of sulfonation. In the reaction kettle, add an appropriate amount of 4-chloroaniline and add a sulfonating reagent, such as concentrated sulfuric acid. Concentrated sulfuric acid is both a reactant and a solvent. Control the reaction temperature to a specific range, generally about 100-180 ° C. This temperature range can make the reaction proceed in an orderly manner and ensure a high yield. If the temperature is too low, the reaction will be slow; if it is too high, side reactions will easily occur. During the reaction, closely observe, because the sulfonic acid group will replace the hydrogen atom at a specific position in the benzene ring, after a series of complex chemical changes, 4-chloroaniline-2-sulfonic acid is gradually formed. After the reaction is completed, the reaction liquid can be cooled, and 4-chloroaniline-2-sulfonic acid crystals can often be precipitated. After filtration, washing, drying and other steps, a pure product can be obtained.
Second, other related compounds are also used as starting materials and prepared by multi-step reaction. If a specific halogenated aromatic hydrocarbon is selected, an amino group is first introduced through a substitution reaction and then sulfonated. However, this path has cumbersome steps and strict requirements for controlling the reaction conditions. Each step of the reaction needs to be precisely regulated, from the proportion of reactants, reaction temperature to reaction time, all affect the purity and yield of the final product. In comparison, the direct sulfonation of 4-chloroaniline is more simple and efficient, so it is widely used in industrial production. With its advantages of simple steps and moderate cost, it has become the mainstream method for preparing 4-chloroaniline-2-sulfonic acid.

And it needs to be stored in isolation from oxidants, acids, alkalis, etc. Due to its active chemical properties, contact with such substances may cause violent reactions and cause danger.
As for transportation, the packaging must be tight and firm to prevent damage and leakage. During the handling process, the operator should be light and unloaded, and must not operate brutally to avoid damage to the packaging due to collision and vibration. The transportation vehicle should also be clean and free of other chemicals left behind to avoid adverse reactions with it. And during transportation, high temperature and sun exposure should be avoided, and it is advisable to choose an appropriate time period for driving. If it passes through special road sections, such as densely populated places, it is more prudent to drive to ensure safe transportation.
