What are the physical and chemical properties of 2,5-difluorobenzenesulfonamide?

2% 2C5-diethoxybenzaldehyde is an important raw material for organic synthesis. Its physical and chemical properties are as follows:

** Physical properties **:
This substance is mostly colorless to light yellow liquid at room temperature, with a clear appearance and a special aroma. The boiling point is about 265-267 ° C. This boiling point characteristic allows it to be separated and purified by distillation and other means under specific temperature conditions. The melting point is -11 ° C, indicating that it is stable in a liquid state at room temperature. The relative density is about 1.03 (20 ° C), which is slightly lighter than water. In the coexistence system of water and other organic phases, it will be distributed according to the density difference.

** Chemical properties **:
In its molecular structure, aldehyde groups (-CHO) are active. Oxidation reactions can occur. In case of strong oxidants such as potassium permanganate, aldehyde groups are easily oxidized to carboxylic groups, which are then converted into 2,5-diethoxybenzoic acid; when reacted with weak oxidants such as Torun reagent (silver ammonia solution), bright silver mirrors can be formed, which is a typical characteristic reaction of aldehyde groups and is often used for the identification of aldehyde substances. At the same time, aldehyde groups can also participate in reduction reactions. Under the action of reducing agents such as sodium borohydride, aldehyde groups can be reduced to hydroxyl groups to generate 2,5-diethoxybenzyl alcohol.

In addition, the ethoxy group on the benzene ring changes the electron cloud density of the benzene ring, which affects the activity of the electrophilic substitution reaction of the benzene ring. Under suitable conditions, halogenation, nitrification, sulfonation and other electrophilic substitution reactions can occur, and the ethoxy group is an ortho and para-site group, and the substitution reaction mainly occurs in the adjacent or relative position of the benzene ring and the ethoxy group.

What is the production method of 2,5-difluorobenzenesulfonamide?

The preparation method of 2% 2C5 -diethylbenzaldehyde oxime ester is as follows:

First take an appropriate amount of raw materials, including specific benzaldehyde derivatives, and precisely control their dosage. This is the basis for preparation. The obtained benzaldehyde derivatives are placed in a reactor, and the reactor needs to be clean and dry to avoid impurities interfering with the reaction.

Then, add an appropriate amount of oxime reagent. The choice of this reagent is extremely critical and needs to meet the characteristics and requirements of the reaction. When adding the oxime reagent, the speed should be slow, and at the same time, stir at a constant speed with a special stirring device to fully mix the two to promote the uniform progress of the reaction.

During the reaction process, temperature control is indispensable. Maintain the reaction system at a specific temperature range, which requires repeated testing and accurate measurement. If the temperature is too high, side reactions may occur, affecting the purity of the product; if the temperature is too low, the reaction rate will be slow and take too long.

After the oximization reaction reaches the expected degree, that is, the reaction index of the system meets the preset standard, the subsequent esterification steps are carried out. Select the appropriate esterification reagent and add it in a certain proportion. The esterification process also requires precise control of the reaction conditions, such as temperature, reaction time and the ratio of reactants.

After the esterification reaction is completed, the reaction products are separated and purified. A variety of separation techniques, such as distillation and extraction, can be used to remove unreacted raw materials, by-products and impurities to obtain high-purity 2% 2C5-diethylbenzaldehyde oxime ester. The entire preparation process requires strict follow of operating procedures and attention to detail to ensure the quality and yield of the product.

What is the price range of 2,5-difluorobenzenesulfonamide in the market?

The price of 2% 2C5-diethylbenzaldehyde oxime in the market varies with time, place and quality, and it is difficult to determine the exact number. Its price often depends on the supply and demand situation, the complexity of the process, and the quality of the product.

In the market of chemical raw materials, if the quantity is quite large, and the quality is accurate for industrial use, the price may be relatively easy. If the quantity is small, and the high purity product is required, if it is suitable for the field of fine chemicals and scientific research, the price will be very expensive.

Looking at the chemical market conditions, 2% 2C5-diethylbenzaldehyde oxime of ordinary purity is purchased in bulk, and the price per kilogram may be in the range of several hundred yuan. If it is of high purity, more than 99%, and the impurities are controlled at a very small level, the price per kilogram or more than 1,000 yuan, or even higher.

However, the market is unstable, and the price changes at any time. In the near future, the price of raw materials, energy costs, and transportation information will also change. If you want to know the exact price, you should consult chemical raw material suppliers, traders, or refer to the quotation of professional chemical information platforms to get the current price.

What are the storage conditions for 2,5-difluorobenzenesulfonamide?

2% 2C5-diethoxybenzaldehyde is an organic compound, and its storage conditions are quite exquisite. This substance should be placed in a cool, dry and well-ventilated place. Because a cool environment can slow down its chemical reaction rate and make its properties more stable; dry place can avoid its hydrolysis by moisture to maintain purity; well-ventilated can avoid its accumulation due to volatilization during storage, which may cause safety risks.

In addition, keep away from fire and heat sources. Fire and heat sources can easily cause combustion or even explosion because of their flammability. And should be stored separately from oxidants, acids, bases, etc., and should not be mixed. The edge oxidant will oxidize with 2% 2C5-diethoxybenzaldehyde, and acid and alkali will come into contact with it or cause chemical reactions, which will damage its quality.

The container in which this substance is stored must also be tightly sealed. A good seal can prevent its volatilization and escape, and can also avoid the intrusion of impurities such as external air and moisture. After taking it, be sure to seal the container as it was in time.

During storage, it should also be checked regularly. Check whether its appearance has changed, and check whether its purity is still the same. If any abnormalities are seen, they should be properly disposed of as soon as possible to ensure its quality and safety. Therefore, it is necessary to properly store 2% 2C5-diethoxybenzaldehyde so that it can achieve the expected effect when used.
