What are the methods for preparing 4,4 '-dichlorobenzenesulfonylaniline?
4,4 '-Dihydroxybenzophenone is an important intermediate in organic synthesis and is widely used in many fields. The common preparation methods are as follows:
First, resorcinol and benzoic acid are used as raw materials and prepared by Fu-gram acylation reaction. This reaction requires Lewis acid such as anhydrous aluminum trichloride as a catalyst. At a suitable temperature, resorcinol interacts with benzoic acid to generate 4,4' -dihydroxybenzophenone. The raw materials of this method are relatively easy to obtain, and the reaction conditions are relatively mild. However, during the reaction process, the catalyst anhydrous aluminum trichloride is very easy to decompose in contact with water, which requires a high reaction environment. During subsequent treatment, the catalyst residue needs to be carefully removed to avoid affecting the purity of the product.
Second, phenol and phosgene are used as starting materials. Phosgene is acylated with phosgene first, and then the target product can be obtained through steps such as hydrolysis. Although this path can effectively synthesize 4,4 '-dihydroxybenzophenone, phosgene is a highly toxic gas. During use, storage and transportation, extra caution is required, and safety procedures are strictly followed to prevent serious harm caused by leakage.
Third, the reaction is carried out with p-hydroxybenzoic acid and p-hydroxybenzoyl chloride as raw materials. The two can be condensed under appropriate conditions to obtain 4,4 '-dihydroxybenzophenone. The reaction steps of this method are relatively simple, and the purity of the product is easy to control. However, the chemical properties of the raw material p-hydroxybenzoyl chloride are active, and its stability should be paid attention to when storing, and a certain amount of by-products may be produced during the reaction process, which needs to be purified by suitable separation methods.
When preparing 4,4' -dihydroxybenzophenone, it is necessary to carefully select the appropriate preparation method according to the actual situation, considering the cost of raw materials, reaction conditions, safety factors and product purity, etc., in order to achieve the goal of efficient, safe and economical synthesis.

What are the environmental effects of 4,4 '-dichlorobenzenesulfonylaniline?
4,4 '-Dihydroxybenzophenone, this substance is extremely harmful to the environment. It has endocrine disrupting properties, like an undercurrent hidden in the environment, quietly affecting the normal physiology of organisms. Many studies have shown that it can interfere with the secretion, synthesis and metabolism of hormones in organisms, causing hormone imbalance. For example, in aquatic organisms, it can cause abnormalities in the reproductive system of fish, reduce the amount of eggs laid, reduce the hatching rate, and cause concern for the survival of the population.
And because of its stable chemical structure, it is difficult to degrade naturally and persists in the environment. Once released into soil and water bodies, it will accumulate for a long time and pollute soil and water sources. This pollution will be transmitted and enriched along the food chain, from tiny plankton to huge mammals and even humans. If people consume it through diet, respiration, or cause health problems, such as affecting reproductive function and increasing the risk of cancer, it also poses a threat to the development of children's nervous system.
In terms of ecosystems, 4,4 '-dihydroxybenzophenone disrupts ecological balance. It affects the activity and community structure of microorganisms, hinders material circulation and energy flow. If soil microorganisms are affected by it, the decomposition of organic matter slows down and soil fertility is damaged. And it is also harmful to plants, interferes with plant hormone balance, affects growth and development, causes crop production, and affects the stability and function of the entire ecosystem. Therefore, the impact of 4,4' -dihydroxybenzophenone on the environment should be given high attention, and efforts should be made to properly deal with it to protect ecological security.
