3,5-Diallyl benzoic acid is a kind of organic compound. Its physical properties are as follows:
Looking at its shape, under normal circumstances, it is mostly white to light yellow crystalline powder, like fine snow broken jade, with a fine texture. Smell its taste, it has a slightly specific fragrance, but it is not a rich and pungent taste, but a relatively light and characteristic smell.
When it comes to the melting point, it is about a specific temperature range. This melting point characteristic is crucial in the identification and purification of the substance. It is like a precise ruler to measure the purity and properties of the substance. When the temperature rises near the melting point, the substance disappears like ice in the warm sun, and gradually melts from the solid state to the liquid state, showing the wonderful transformation of the material state.
In terms of solubility, in organic solvents, such as ethanol and acetone, it has a certain solubility. Just like fish entering water, it can blend with organic solvents to form a uniform system. However, in water, its solubility is not good, just like the intolerance of oil and water, and this characteristic also determines its dispersion and application in different environments.
Furthermore, its density is also a specific value, which reflects the mass of a substance per unit volume. Like a label for measuring the weight and density of an object, it provides an important reference for its application in various practical application scenarios, such as mixing, separation, etc., so that its application in the chemical industry, materials and other fields can be more accurately controlled.

There are several common methods for the synthesis of 3,5-diethoxybenzyl alcohol:
One is to use p-hydroxybenzaldehyde as the starting material. First, it is synthesized by Williamson ether with halogenated ethane under alkaline conditions. In this reaction, potassium carbonate can be selected as the base, and halogenated ethane such as bromoethane is appropriate. The alkaline environment promotes the formation of phenolic hydroxyl oxygen anions of p-hydroxybenzaldehyde, which in turn undergoes a nucleophilic substitution reaction with halogenated ethane to generate p-ethoxybenzaldehyde. Subsequently, after the reduction reaction of p-ethoxybenzaldehyde, the aldehyde group can be reduced to an alcoholic hydroxyl group in a suitable solvent such as methanol, and 3,5-diethoxybenzyl alcohol can be obtained. The reaction process is clear, the reaction conditions of each step are relatively mild, and the yield is relatively considerable.
The second is resorcinol as the starting material. The resorcinol first reacts with haloethane under alkali catalysis, similar to Williamson ether synthesis, so that the two hydroxyl groups of resorcinol are replaced by ethoxy groups to generate 3,5-diethoxy phenol. Next, 3,5-diethoxy phenol and halogenated methyl reagents, such as chloromethyl methyl ether, etc., under the catalysis of Lewis acid such as anhydrous zinc chloride, a Friedel-Crafts hydrocarbon reaction occurs, and chloromethyl is introduced into the phenyl ring. Finally, through the reduction step, the target product 3,5-diethoxy benzyl alcohol can be obtained by reducing with strong reducing agents such as lithium aluminum hydride. This route has a little more steps, but the raw material resorcinol is more common and inexpensive.
Furthermore, the corresponding benzoate can be used. First, benzoate is reduced to the corresponding benzyl alcohol by reduction reaction, such as lithium aluminum hydride, and then the benzyl alcohol is etherified with halogenated ethane under basic conditions. The same principle of Williamson ether synthesis can be followed to synthesize 3,5-diethoxy benzyl alcohol. This method requires attention to the control of the reaction conditions of the reduction and etherification steps to ensure the purity and yield of the product.

When storing and transporting 3,5-diethylbenzamide, many precautions should be followed carefully.
In terms of storage, the first environment should be selected. It should be placed in a cool, dry and well-ventilated place to prevent moisture and sun. Because the substance is quite sensitive to temperature and humidity, high temperature or high humidity environment can easily cause its properties to change, and even affect the quality. The warehouse temperature should be controlled in a specific range, and the humidity should also be maintained at an appropriate level. At the same time, it should be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. This is because its chemical properties are active, and contact with the above substances can easily cause chemical reactions, or cause serious accidents such as fire and explosion.
The choice of storage container is also crucial. Be sure to use a well-sealed container to prevent the intrusion of external factors such as air and moisture. For commonly used metal or plastic drums, it is necessary to ensure that the material does not react with 3,5-diethylbenzamide, and there is no risk of damage or leakage. During storage, the condition of the container should be inspected regularly. If the container shows signs of corrosion, deformation or leakage, immediate measures must be taken, such as transferring materials, repairing or replacing the container.
When it comes to transportation, the qualifications and conditions of the transportation vehicle must be in compliance. Vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment for emergencies. During transportation, ensure that the container is stable and will not be damaged due to bumps and collisions. Route planning should not be ignored, and densely populated areas and environmentally sensitive areas should be avoided to prevent transportation accidents from causing harm to the people and the environment.
Transportation personnel also need professional training to be familiar with the dangerous characteristics and emergency treatment methods of 3,5-diethylbenzamide. When loading and unloading, it should be handled lightly, and it is strictly forbidden to drop and heavy pressure to avoid leakage due to improper operation. If leakage occurs during transportation, the surrounding people should be evacuated immediately, the warning area should be demarcated, and the corresponding leakage plugging and cleaning measures should be taken quickly to prevent the spread of pollution.

It is difficult to determine the price of 3,5-diethoxybenzaldehyde in the market. The price of the cover often changes for various reasons.
First, the situation of supply and demand is the key. If there are many people who want it, but the supply is small, the price will rise; if there are few people who want it, and there are many suppliers, the price will be depressed.
Second, the price of raw materials for making this product also has an impact. If the price of raw materials increases, the cost will increase, and the market price will also increase; if the price of raw materials decreases, the cost will decrease, and the price may decrease.
Third, the coarseness of the process and the yield are related to the cost and pricing. Make good use of smart skills, increase its yield, reduce its cost, and the price may be competitive.
Fourth, the regulations of the business market and the tax system are also related to the price. Where the tax is large and light, the price may be more appropriate; where the regulations are small and the tax is heavy, the price may be slightly higher.
In today's city, the price is roughly several hundred yuan per kilogram. However, this is only an approximate amount, and the exact price depends on the real-time business conditions, the quality and the volume of transactions. If a buyer wants to get a definite price, he should consult various suppliers and compare the price in detail before he can get a good price.
