What is the preparation method of 4-fluorobenzene-1,2-dicarboxylic acid?
To prepare 4-bromo-1,2-diacetic acid, you can do it according to the following method.
First take an appropriate amount of 1,2-dibromoethane and place it in the reactor. Add excess sodium cyanide to it, and under the action of appropriate temperature and catalyst, make the cyano group replace the bromine atom. The reaction formula is: $BrCH_ {2} CH_ {2} Br + 2NaCN\ stackrel {catalyst} {\ longrightarrow} NCCH_ {2} CH_ {2} CN + 2NaBr $. This step needs to pay attention to the precise control of the reaction conditions. Sodium cyanide is highly toxic, and the operation must be cautious.
When the reaction is fully completed, take out the product NCCH_ {2} CH_ {2} CN, put it in another reaction vessel, add an appropriate amount of dilute sulfuric acid and heat to promote the hydrolysis of cyanide to carboxyl groups, the reaction formula is as follows: $NCCH_ {2} CH_ {2} CN + 4H_ {2} O + 2H_ {2} SO_ {4}\ stackrel {\ triangle} {\ longrightarrow} HOOCCH_ {2} CH_ {2} COOH + 2NH_ {4} HSO_ {4} $.
So far, after this two-step reaction, 4-bromo-1,2-diacetic acid can be obtained. However, during the preparation process, the temperature, time, and proportion of reactants in each step of the reaction need to be carefully controlled, and the reagents used are often dangerous, such as sodium cyanide, which is highly toxic, and sulfuric acid, which is corrosive. Therefore, safety procedures must be strictly followed during operation, and protective measures must be taken to ensure the safety and success of the experiment.
What are the precautions for 4-fluorobenzene-1,2-dicarboxylic acid in storage and transportation?
4-Hydroxynaphthalene-1,2-diacetic acid is a commonly used raw material in chemical industry. During storage and transportation, many points should be paid attention to.
First words storage. This substance should be placed in a cool, dry and well-ventilated place. Cover because of its nature, if in a humid environment, it is easy to absorb moisture and deteriorate, causing its chemical properties to change, affecting subsequent use. And it must be kept away from fire and heat sources to prevent fire or other safety accidents. In addition, it should be stored separately from oxidants, acids, bases, etc., and cannot be mixed. It may chemically react with these substances, damage its own quality, and even generate dangerous products. At the same time, the storage area should be equipped with suitable materials to contain the leakage, in case of leakage, it can be dealt with in time.
Second talk about transportation. During transportation, it is necessary to ensure that the container does not leak, collapse, fall or damage. Transportation vehicles should be equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. Summer transportation should be carried out in the morning and evening to avoid high temperature periods, because high temperature may cause it to evaporate or have unstable reactions. During transportation, it should be protected from sun exposure, rain and high temperature. Road transportation should be carried out according to the specified route, and do not stop in residential areas and densely populated areas. If it is rail transportation, it is also necessary to follow relevant regulations to ensure transportation safety. In short, whether storing or transporting 4-hydroxynaphthalene-1,2-diacetic acid, it is necessary to operate in strict accordance with regulations to ensure personnel safety and material quality.
What is the market price range for 4-fluorobenzene-1,2-dicarboxylic acid?
4-Hydroxyquine-1,2-diacetic acid, the price range of this product in the market is difficult to determine. The price often changes due to many reasons, such as the purity of the quality, the supply and demand of the market, the complexity and simplicity of the system, and the distance of transportation, etc., are all related to it.
If the quality is pure and refined, it is the best product, and it is popular in the market, but the supply is thin, and the production is complicated, and the transportation is long, the price will be high, or it can reach the realm of high prices. On the contrary, if the quality is slightly inferior, the market needs to be slow, and the system is easy and easy to transport, the price is relatively low.
I have heard that among the cities, the price is low, or to tens of dollars per catty; while the high, or up to hundreds of dollars per catty, or even more than a thousand dollars. However, these are all approximate values, which are realized in various places at all times, and the price may fluctuate up and down, making it difficult to generalize. To know the exact price, you must carefully consider the local market conditions at that time, and consult the industry and merchants to obtain a close estimate.
