What are the synthesis methods of 3-fluoro-5-iodobenzaldehyde?
To prepare 3-bromo-5-chlorobenzoic acid, the following ancient methods can be used:
First, benzoic acid is used as the starting material. First, benzoic acid is brominated to obtain isobromobenzoic acid. The carboxyl group in captobenzoic acid is the meta-locator, and the bromine atom is multi-meta-localized during bromination. This step can be used in a suitable solvent, such as glacial acetic acid, with liquid bromine as the bromine source, adding an appropriate amount of catalyst, such as iron powder or iron tribromide, and heating to promote the reaction. After the reaction is completed, the isobromobenzoic acid can be obtained by separation and purification.
The isobromobenzoic acid is chlor In a suitable reaction system, chlorine is used as the chlorine source, and a suitable catalyst, such as aluminum trichloride, is selected to control the reaction conditions. The chlorine atom is introduced into the 5-position of isobromobenzoic acid to obtain 3-bromo-5-chlorobenzoic acid. This reaction needs to be carefully controlled to control the reaction temperature and the proportion of reactants to avoid the formation of too many by-products.
Or chlorination of benzoic acid to obtain isochlorobenzoic acid first. During the chlorination process, chlorine gas is passed through with an appropriate solvent, and a catalyst is added, such as anhydrous ferric chloride. After heating the reaction, m-chlorobenzoic 3-Bromo-5-chlorobenzoic acid can also be obtained by bromine atoms entering the 3-position of isochlorobenzoic acid under suitable conditions.
During operation, all reaction conditions need to be carefully regulated. After the reaction is completed, the separation and purification of the product are also crucial. 3-Bromo-5-chlorobenzoic acid with high purity can be obtained by recrystallization, column chromatography, etc.
What are the physical properties of 3-fluoro-5-iodobenzaldehyde?
The object of the 3-5-petal armor is rational, and it is interesting, and I will go through it one by one.
The back of this shell is special, hard and often, like the shield of the sky, it can resist the invasion of external forces. Its color is more dark brown or ink, and it is stained with color, just like the robe of the ancients, which is the wonder of nature.

In addition, the bones of the body are solid, and the support is large, so that the body can bear a certain weight without suffering.
In this way, the physical reason of 3-5-petal armor, armor, limbs and parts, all contain the wonders of heaven and earth creation, which is one of the wonders of nature.
What is the market price of 3-fluoro-5-iodobenzaldehyde?
In today's market, the price of the five-grade crab nail sharks in Sanchuan varies with time, place and quality.
If it is during the peak production period of crab nail sharks, the supply is abundant, and the price may be slightly cheaper. In the land where sharks are produced, near the water, the cost of long-distance trafficking is saved, and the price tends to be easy. However, if the production of sharks is rare, or in remote places where sharks are lacking, the price will rise.
And the quality of crab nail sharks is also the main reason for the price. Those with a plump body, tender meat, and bright color will be priced higher than usual. Its appearance is good, or it is favored by officials and dignitaries, and those who seek it will be expensive. If the shark body is thin and the meat quality is poor, the price will be low.
In the past, on festive occasions, wealthy families competed to buy crab nail sharks for banquets, causing their prices to rise. In normal times, the demand is slightly slower and the price is stable.
There are also the means of business sales and the balance between supply and demand in the market, which all affect the price. Good operators may be able to take advantage of the situation to set prices and seek considerable profits. Therefore, if you want to know the market price of Sanchuan Five-Grade Crab Nail Sharks, you must carefully observe the current supply and demand, and the quality of all things, in order to obtain its exact price.
What should be paid attention to when storing and transporting 3-fluoro-5-iodobenzaldehyde?
3 - 5 - Crab armor should be hidden in the same place, and it should be kept in mind.
The first place to hide is the environment. Crab armor likes to be hidden, and it should be placed in a low-pass place, and it should not be exposed to light. If it is hidden in the container, it needs to be covered with aquatic plants or cloth to protect it from water and death.
In addition, the crab armor is the same, and it should be separated. Crab is fierce, and the armor is also aggressive. If it is mixed and mixed, it is feared that it will be damaged by each other, causing it to suffer or die.
It is especially important to cover it. Crabs should be kept warm to avoid damage and reduce their energy consumption. A shell also needs to be properly wrapped, placed in a solid and transparent container, a cloth or an ice pack, and the temperature is low.
Furthermore, the speed of the shell should be fast. The survival limit of crab shells is limited, and it is easy to die due to lack of water, lack of oxygen or poor environment. Therefore, it is necessary to take a quick and effective way, such as cold clothing is especially good, and pay attention to its performance on the way. If it is normal, and take care of it.
In this way, for 3-5-5-year-old crab armor, follow the requirements to keep it alive and maintain its beautiful taste.
