The synthesis method of 3,5-diene heptanal oxime ether can be done according to the following method.
First take an appropriate amount of heptanal and place it in a clean reactor. With a fine temperature control device, the temperature in the kettle is maintained within a specific range, such as between 20 and 25 degrees Celsius. At this temperature, slowly drop in a quantitative hydroxylamine solution. When dripping, it is necessary to continuously stir to make the two fully contact and react. The molar ratio of hydroxylamine and heptanal should be precisely prepared, about 1.2:1. This ratio can promote the reaction to be more complete.
When the hydroxylamine is added dropwise, continue to stir for about an hour to make the reaction more complete. Then, the temperature of the reaction system is gradually increased to 50 to 55 degrees Celsius, and an appropriate amount of alkali is added as a catalyst, such as potassium hydroxide, in an amount of about 3% of the total mass of the reactants. The addition of alkali can accelerate the reaction process. At this temperature, the reaction continues for about two hours.
When the above reaction is completed, the reaction solution is cooled to room temperature, and then extracted with an organic solvent, such as dichloromethane. When extracting, multiple operations are required, usually three times, to ensure that the target product is fully transferred to the organic phase. The organic phase is collected and dried with anhydrous sodium sulfate to remove the moisture.
After drying, the organic phase is placed in a rotary evaporator. Under a suitable vacuum degree and temperature, such as a vacuum degree of 0.08MPa and a temperature of 40 to 45 degrees Celsius, the organic solvent is evaporated to remove the crude product.
Then the crude product is finely purified by column chromatography. Silica gel is used as the stationary phase, and the mixture of petroleum ether and ethyl acetate in a specific ratio, such as 4:1, is used as the mobile phase. The crude product is sampled on a chromatography column, slowly rinsed, and the fraction containing the target product is collected. Finally, the residual solvent is removed by reduced pressure distillation to obtain a pure 3,5-dienyl heptanoxime ether. In this synthesis method, although the steps are complicated, each step is carefully controlled to obtain a product with higher yield and purity.

3,5-Diethylbenzaldehyde oxime ether in storage and transportation, there are a number of things to pay attention to, must not be ignored.
First, the nature of this thing may be unstable, easy to react with other things. Therefore, during storage and transportation, it must be separated from strong acids, strong alkalis, strong oxidizing agents, etc., do not coexist. These substances meet with it, or cause violent reactions, causing leakage, fire, and even explosion risk, endangering the safety of the surrounding.
Second, temperature and humidity also affect it. It should be stored in a cool, dry and well-ventilated place. If it is in a high temperature environment, it may cause its volatilization to accelerate, and the concentration will rise in a limited space, increasing the risk of ignition and explosion; if the humidity is too high, it may cause the substance to absorb moisture and deteriorate, damaging its quality and efficiency.
Third, the packaging must be tight. Choose the appropriate packaging material to prevent leakage. If the package is damaged and the material spills out, it will not only be wasted, but also pollute the environment, and contact with the human body is also harmful to health. When handling, handle it with care, do not subject the package to severe vibration or collision, and keep it in good condition.
Fourth, during transportation, choose the means and method of transportation that are compliant. According to its dangerous characteristics, match corresponding protection and emergency measures. Transportation personnel should also be professionally trained to understand material characteristics and emergency response methods. In case of emergencies, they can respond quickly and properly to minimize harm.
In short, when storing and transporting 3,5-diethylbenzaldehyde oxime ether, it must be operated in strict accordance with regulations in the environment, packaging, transportation and other links, and be cautious to ensure safety.

For 3,5-diethylbenzoic anhydride, the price of the market is roughly variable, and the price of the cover varies due to various reasons. First, the price of raw materials is a factor. If the price of all the raw materials used to make this thing is high, the price of 3,5-diethylbenzoic anhydride will also rise; if the price of raw materials is low, the price may be slightly reduced. Second, the trend of supply and demand also affects its price. If there are many people in the market who want it, but there are few people who supply it, the price will increase; if the supply exceeds the demand, the price may fall. Third, the simplicity of the manufacturing process and the amount of labor costs are also related to the price. The more complex the process, the more expensive the labor, and the higher the price.
At present, the price of 3,5-diethylbenzoic anhydride in the market fluctuates between hundreds and thousands of yuan per kilogram. If it is of high quality and suitable for special needs, the price may be higher. If you want to know the exact price, you can get a near-real price by consulting the supplier of chemical materials, or checking the quotation in the relevant trading platform. And the price varies from place to place due to different freight and taxes, so it cannot be generalized.
