The carboxylic acid anhydride of 2% 2C6-dimethylpyridine nitrogen oxide is prepared by using 2% 2C6-dimethylpyridine as the starting material, going through the oxidation step to obtain 2% 2C6-dimethylpyridine nitrogen oxide, and then interacting with the acylating agent to obtain the carboxylic acid anhydride.
First, 2% 2C6-dimethylpyridine nitrogen oxide is prepared. Hydrogen peroxide or peracid is often used as the oxidant, and in a suitable solvent, such as glacial acetic acid, dichloromethane, etc., the temperature and reaction time are controlled to oxidize 2% 2C6-dimethylpyridine. For example, hydrogen peroxide is used as an oxidizing agent. When heated to 40-60 degrees Celsius in glacial acetic acid solvent and the number of reactions, 2% 2C6-dimethylpyridine nitrogen oxide can be obtained. In this process, hydrogen peroxide decomposes reactive oxygen species, attacks the nitrogen atoms of the pyridine ring, forms nitrogen-oxygen bonds, and obtains the target product.
Then 2% 2C6-dimethylpyridine nitrogen oxide and acylating reagents are used to produce carboxylic acid anhydride. Commonly used acylating reagents include acetic anhydride, propionic anhydride, etc. Taking acetic anhydride as an example, place 2% 2C6-dimethylpyridine nitrogen oxide and acetic anhydride in a reactor, add an appropriate amount of catalyst, such as sulfuric acid, p-toluenesulfonic acid, etc., and heat it up to 80-100 degrees Celsius. When the reaction number is reached, the acyl group of the acylating reagent interacts with the oxygen atom of 2% 2C6-dimethylpyridine nitrogen oxide to remove a molecule of organic acid and form a carboxylic acid anhydride of 2% 2C6-dimethylpyridine nitrogen oxide.
During the preparation process, attention should be paid to the control of reaction conditions, such as temperature, pH, and the ratio of reactants, etc., to improve the And the reagents and solvents used are toxic and corrosive. During operation, it is necessary to adhere to safety procedures and take protective measures.

Wen Jun inquired about the market price of dimethacrylic acid, and this matter should be studied in detail. Prices in the city often change due to the current situation, supply and demand, and cannot be generalized.
The business of the merchant, supply and demand are the main requirements. If the demand for this product is wide, there are many users, or the raw materials are rare and difficult to make, the price will be high. On the contrary, if the supply is abundant, there are few applicants, and the price will become easy.
There are various other reasons. The place of origin is far and near, which is related to the freight. If you come from a distance, the price may increase; the quality of craftsmanship affects the quality. The price of refined products is high, and the price of mundane products is low. And the market is diverse, the competition is fierce, and the merchants use various means to attract customers for profit, and the price fluctuates accordingly.
If you want to know the exact price, you can get a detailed number when you visit the chemical market, consult the merchants specializing in this industry, or check the industry classics and market reports. The market is volatile, and the price changes at any time. You must pay attention to the changes of the times, and find a good plan when you get the right price.

2% 2C6-dimethylpyridine nitric oxide anhydride, when storing and transporting, there are several points of attention that need to be carefully observed.
The first word of storage, it should be placed in a cool, dry and well-ventilated place. This is due to its nature or being disturbed by temperature and humidity. If it is placed in a warm and humid place, it may cause qualitative change and damage its effectiveness. And it must be kept away from fire and heat sources. It may be flammable. In case of open flames and hot topics, it is easy to cause danger, fire or even explosion. It should also be separated from oxidants, acids, bases and other substances to prevent their interaction and chemical reactions from causing unexpected changes.
As for transportation, there are also many details. Before transportation, ensure that the packaging is complete and sealed to prevent leakage. Choose suitable transportation tools, and during transportation, it should be protected from exposure to the sun, rain, and high temperature.
