What are the physical properties of 2 '-iodo-5' -fuoroacetophenone?
2% 27 - iodo - 5% 27 - fluoroacetophenone is 2 '-iodine-5' -fluoroacetophenone, which is an organic compound with unique physical properties.
Looking at its properties, it is mostly crystalline solid under normal conditions, fine and regular, and solid to the touch. Its color may be colorless to light yellow, such as the first light of the morning, pure and elegant. This color is derived from the specific absorption and reflection of light by the molecular structure.
When it comes to the melting point, around [specific melting point value], at a specific temperature, the lattice structure begins to disintegrate, gradually melting from the solid state to the liquid state, just like ice and snow melting in spring. The boiling point also has a fixed number, which is about [specific boiling point value]. At this temperature, the molecule can break free from the liquid phase and escape into the gas phase.
In terms of solubility, in organic solvents such as ethanol and ether, such as fish in water, it can be well miscible. Due to the principle of similar phase solubility, its organic structure is adapted to the force between organic solvent molecules. However, in water, the solubility is very small, just like oil and water are difficult to melt, because its hydrophobic structure is contrary to the polarity of water molecules.
The density is [specific density value] compared to water. If placed in water, such as a stone sinking abyss, it will sink to the bottom. In addition, 2 '-iodine-5' -fluoroacetophenone is volatile and gradually dissipates in the air. Although it is invisible, its unique odor can be observed, which poses challenges for related operations and requires careful precautions.
What are the synthesis methods of 2 '-iodo-5' -fuoroacetophenone?
2% 27 - iodo - 5% 27 - fuoroacetophenone, that is, 2 '-iodine-5' -fluoroacetophenone, is synthesized as follows:
First, by using 5 - fluoroacetophenone as the starting material. This is due to the presence of fluorine atom substitution on the benzene ring in the 5 - fluoroacetophenone structure, which lays the foundation for the introduction of 5 '-fluorine in the target product. 5 - fluoroacetophenone is dissolved in a suitable organic solvent, such as glacial acetic acid, which allows the reactant to be sufficiently dispersed and facilitates the reaction. Then, an appropriate amount of iodizing reagent, such as N - iodosuccinimide (NIS), is slowly added to the system. NIS is a commonly used iodizing reagent, which can effectively provide an iodine source. The reaction process needs to control the temperature, usually at a low temperature, such as 0 ° C - 5 ° C. Because of the low temperature, the reaction can occur smoothly and avoid too many side reactions. After the reaction for a period of time, TLC (thin layer chromatography) tracks and monitors the reaction process. When the raw material point is basically eliminated, it indicates that the reaction has reached the expected level. Then, after the reaction is completed, the post-treatment is carried out. The reaction liquid is poured into ice water, and the precipitation is precipitated. This operation allows the product to be precipitated from the reaction system and initially separated from impurities. After that, the precipitation is collected by filtration, and then recrystallized with a suitable solvent, such as ethanol, and the product is further purified to obtain a relatively pure 2 '-i
Secondly, another synthesis idea is to use 2-iodobenzoic acid as the starting material. First, 2-iodobenzoic acid and ethanol are esterified under the catalysis of concentrated sulfuric acid to generate ethyl 2-iodobenzoate. Concentrated sulfuric acid acts as a catalyst to speed up the esterification reaction rate. The reaction is carried out under the condition of heating and reflux to fully react the reactants. Afterwards, using the principle of reacting magnesium metal with halogenated hydrocarbons to prepare Grignard reagents, 2-iodobenzoic acid ethyl ester is reacted with magnesium chips in anhydrous ether to make Grignard reagents. Anhydrous ether provides an anhydrous environment for the reaction and ensures the stable generation of Grignard reagents. Then, an appropriate amount of fluoromethane gas is introduced into the Grignard reagent, and fluoromethane participates in the reaction as a fluorine source, and a nucleophilic substitution reaction occurs to form new carbon-carbon bonds and carbon-fluorine bonds. After the reaction is completed, 2 '-iodine-5' -fluorobenzene is finally obtained through conventional post-processing steps such as hydrolysis and acidification.
2 '-Iodo-5' -fuoroacetophenone What to pay attention to when storing and transporting
2% 27 - iodo - 5% 27 - fluoroacetophenone, that is, 2 '-iodine-5' -fluoroacetophenone, should be carefully stored and transported.
It is an organic compound with certain chemical activity. When storing, the first choice of environment. It should be placed in a cool, dry and well-ventilated place. It may cause quality deterioration if it is placed in a high temperature and humid place, or it may cause chemical reactions. For example, high temperature may cause it to decompose, humid environment or cause it to react with water vapor, resulting in impurities.
Furthermore, storage containers should also be carefully selected. Corrosive-resistant materials such as glass or specific plastic containers should be used. Due to the reaction of 2 '-iodine-5' -fluoroacetophenone or with certain metals, the container is corroded and its own purity is affected.
When transporting, safety is of the utmost importance. It is necessary to ensure that the packaging is tight to prevent leakage. If it leaks, it will not only damage the goods, but also may endanger the transporter and the surrounding environment. And the transportation process should avoid high temperature, vibration and collision. High temperature or cause it to evaporate and decompose, and vibration and collision may cause damage to the package, causing the risk of leakage.
In addition, relevant regulations and standards must be followed regardless of storage or transportation. Operators should be familiar with the characteristics of this object and emergency treatment methods. In the event of an accident, they can quickly and properly dispose of it to reduce hazards.
What is the market price of 2 '-iodo-5' -fuoroacetophenone?
The price of "2 '-iodine-5' -fluoroacetophenone" is straight, and it is difficult to determine it. The price of the cap depends on many reasons.
First, it is difficult to make. If it is difficult to make, special materials and precise and strict methods are required, and the price will be high; if it is easier to make, and the materials are also easy to obtain, the price will be low.
The second one is the state of demand and supply. If there is a lot of demand in the city, and the supply is small, the price will increase; if the supply exceeds the demand, the price will drop.
The second time, the quality is good or bad. Those who are of high quality, the price is always high; those who are of lower quality, the price is low.
There are also factors such as competition in the market, changes in time, etc. In today's world, merchants hold their own prices, and the market conditions are transient, so it is difficult to determine their prices. To know the price, you should consult the merchants, or the common conditions of the market, to get a rough outline. To be sure, the exact number of prices is difficult to hide, but you must consider all the reasons and then be able to judge.
