In the past, such sulfonic acids were prepared, or phenols were used as the base first. The reaction between phenol and sulfonating agent is very important. Sulfonating agent, often mainly sulfuric acid, especially concentrated. Phenol and sulfuric acid are mixed slowly in an appropriate ratio at a suitable temperature. Temperature control should not be ignored. If the temperature is too high, the reaction will be excessive and the product will be impure; if the temperature is low, the reaction will be slow and time-consuming.
After mixing, it needs to be stirred evenly to make it fully mixed. In this process, the sulfonic acid group gradually enters the structure of the phenol and forms the precursor of 2-aminophenol-4,6-disulfonic acid according to the specific position.
After that, there may be a step of separation and purification. Because the products of the reaction are often mixed with other things, the ancient methods of sedimentation, filtration, crystallization, etc. must be used to remove impurities. For sedimentation, make heavy impurities sink at the bottom of the vessel; filter, take the clear liquid and discard the residue; crystallization method, make the pure substance precipitate from the solution to obtain pure 2-aminophenol-4,6-disulfonic acid.
Or there is a method of introducing amino groups. At an appropriate time, ammonia or an amino-containing reagent is added to the reaction system, so that the amino group is connected to the structure of the phenol, and it is coordinated with the sulfonic acid group that has been connected, and the final product is obtained.
Although this is not detailed in "Tiangong Kaizi", the principle of chemical engineering is the same in ancient times and modern times. By using ancient methods and referring to modern knowledge, the preparation of 2-aminophenol-4,6-disulfonic acid can be known.
