2-Amino-4,4 '-dichlorodiphenyl ether-2' -sulfonic acid, sodium salt preparation method, although the ancient "Tiangong Kaiwu" does not specify this material, it can be deduced from similar materials and ancient principles.
To make this product, the first thing is to choose suitable raw materials. With compounds containing chlorine, amino and phenyl ether structures as the base, or natural products containing corresponding groups can be found, refined and purified to obtain usable raw materials. For example, in ancient chemical operations, natural sources such as ores and plants are often obtained from natural sources, and purified through multi-step treatment.
The raw materials are ready, and appropriate reaction conditions need to be selected. The temperature, time, solvent, etc. of the reaction are all crucial. In ancient methods, the temperature of the reaction was often controlled by fire, and the reaction time was measured by sundials. In this reaction, a mild temperature may be required, and in a special kettle, water or organic solvent is used as the medium to interact with the raw materials.
During the reaction process, it is necessary to pay attention to the process of the reaction. The degree of the reaction can be roughly judged by ancient methods such as observing the color change of the solution and the formation of precipitation. If the color of the solution changes from light to dark, or there is precipitation gradually emerging, it is a sign that the reaction is going on.
After the reaction is completed, the separation and purification of the product are also key. Filtration, distillation, crystallization and other methods can be used. For example, filter with filter paper or fine fabric to remove insoluble impurities; use distillation to separate solvents and products according to different boiling points; use crystallization to control temperature and solvent concentration to crystallize and precipitate products to obtain pure 2-amino-4,4 '-dichlorodiphenyl ether-2' -sulfonic acid, sodium salt.
Although there is no exact ancient method to follow, according to chemical principles, with ancient skills and wisdom, the method of making this substance can be explored.

In today's world, the business situation is complicated, and the price of things in the market is impermanent. If you want to ask 2 - Amino - 4,4 '- Dichlorodiphenyl Ether - 2' - Sulfonic Acid Sodium Salt in the inter-market price range, it is difficult to say for sure. The price is influenced by many factors. The abundance of raw materials, the difficulty of craftsmanship, the urgency of supply and demand, and the change of times can all make it impermanent.
In the past, or because of the abundance of raw materials and the ease of production, the price may be slightly flat. However, if raw materials are scarce, or the production techniques are complicated, and the cost of manpower and material resources is quite huge, the price will rise. And the demand of the market, if there are many applicants and few suppliers, the price will be higher; if the supply exceeds the demand, the price will be lower.
In addition, in four places, prices are also different. Prosperous cities, convenient transportation, merchants converge, or because of the smooth circulation, the price may be moderate; and remote places, difficult transportation, the price may be high. And different merchants, due to different business policies and cost calculations, set different prices. Therefore, to know the exact price, when you go to the market, ask the merchants, or visit people in the industry, and carefully observe the current situation, you can get it. It is difficult to say a word to cover its price range.
