What are the synthesis methods of 3-chlorothiophenol?
The method of synthesizing mercury is very good.
One method is to take the amount of mercury, put it in a crucible, and set it on a fire for roasting. The fire needs to be made of charcoal to make the firepower uniform and long-lasting. When the mercury is melted into the liquid, it is mixed and thoroughly mixed. However, the mixing liquid needs to be cooled slowly, and the cooling speed needs to be carefully controlled. It is not urgent, nor can it be used. Cold, or mercury can be obtained.
The second method is to use the mercury as the starting material. First, the two are divided and dissolved in water to obtain a clear solution. Then mix the two solutions. Mix the two solutions, and do not need to be mixed, so that the reverse is uniform. In this case, a precipitate is formed in the solution. The precipitate, or the precipitate before the mercury. The precipitate, the precipitate is released, and the water is reversed and washed with clean water to remove it. Then the precipitate is placed in an oven and dried at a low temperature, and it can also become mercury.
The third method is to fill a dense container and fill it into a suitable environment, such as nitrogen and other inert conditions, to prevent oxidation. The powder of mercury is placed in it in a certain proportion, applied with high temperature, and added together. Under high temperature and high temperature, mercury may be able to combine with mercury. However, this method needs to be used, and the operation degree is large, and the control of the degree and force needs to be especially precise. The
method has its own advantages and disadvantages, and it needs to be balanced according to factors such as the required materials and the required materials.

What are the precautions for using 3-chlorothiophenol?
The use of koji sand is related to life, and it is necessary to pay attention to many matters.
When using koji sand, the first thing to pay attention to is its quality. It must be pure and refined, if it contains impurities, or causes the effect of the medicine to be surly, endangering the human body. When purchasing, when you look carefully, observe its color, observe its luster, and examine its shape, you must obtain a pure and flawless product.
Secondly, the dosage system is very important. The sand is fierce and powerful. Although it has the ability to remove diseases, the dosage is slightly poor, and it is a disaster. It should be used with caution. According to the severity of the disease and the strength of the body, the doctor will weigh and consider, and the dose will be accurately determined. Never make an assertion without authorization, and increase or decrease it at will, so as not to cause the medicine to go through the disease and change itself.
Furthermore, the method of processing should not be ignored. Correct processing can reduce its toxicity and increase its curative effect. Or calcining and quenching, or vinegar, each has its own suitability. Follow the ancient method of processing to ensure the safety of drug use. If the processing is improper, such as loss of heat and wrong excipients, not only is the efficacy of the medicine difficult to show, but the toxicity is also difficult to remove, and the legacy is infinite.
When used in combination, you must also be cautious. When used in combination with suitable medicines, it can complement each other and improve the curative effect; if used with the opposite medicine, it will be like ice charcoal, which will cause disaster for a while. Doctors should understand the contraindications of drug compatibility, and choose the drug combination reasonably.
In addition, those who use the drug should also be scrutinized in detail. The old and weak women and children, with poor constitution, have poor tolerance to kaosan, and should be especially careful when using it; those with chronic diseases have insufficient visceral functions, and must also use the drug cautiously. During the medication period, closely observe the body's reaction. If there is any discomfort, immediately stop the drug and seek medical treatment.
In short, although kaosan is a good medicine, its sex is fierce and poisonous. During the use process, it is necessary to be cautious about various matters such as texture, dosage, processing, compatibility, and the person who uses it, in order to seek advantages and avoid disadvantages and protect Kangtai.

What are the preparation methods of 3-chlorothiophenol?
There are several ways to prepare 3-bromovaleric anhydride. One method is to use 3-bromovaleric acid as the base, followed by a dehydrating agent for dehydration and condensation. Usually acetic anhydride, phosphorus oxychloride and the like are used as dehydrating agents. Take an appropriate amount of 3-bromovaleric acid, place it in a clean reaction vessel, slowly add the dehydrating agent, and apply moderate heating and stirring to promote the homogeneity of the reaction. When reacting, pay close attention to the change of temperature, and do not make it too high to avoid side reactions. After the reaction is completed, the product can be purified by appropriate separation methods, such as distillation and recrystallization, to obtain 3-bromovaleric anhydride.
Another method can be used to make its acid chloride from 3-bromovaleric acid, and then react with 3-bromovalerate sodium. First, 3-bromovalerate acid is reacted with chlorination reagents such as thionyl chloride to make 3-bromovaleryl chloride. This step needs to be carried out in an anhydrous environment to prevent hydrolysis of the acid chloride. When the acid chloride is made, it is slowly dripped into the solution of 3-bromovalerate sodium, which also needs to be maintained at an appropriate temperature and pH value. After the dripping is completed, continue to stir for a period of time to complete the reaction. After the reaction, pure 3-bromovalerate anhydride can be obtained through extraction, drying, distillation and other steps.
In another method, if glutaric anhydride is used as the starting material, bromine atoms are introduced through bromination reaction first. Appropriate brominating reagents can be selected, such as bromine, N-bromosuccinimide (NBS), etc. Under suitable reaction conditions, such as light and the presence of initiators, the brominating reagent is reacted with glutaric anhydride to introduce bromine atoms into a specific location to generate 3-bromoglutaric anhydride. After appropriate treatment, the target product 3-bromovaleric anhydride can be obtained. All methods have advantages and disadvantages. When operating, it is necessary to choose carefully according to the availability of raw materials, cost, product purity and other factors.
