The synthesis method of 3,5-diallyl benzoate has been known in ancient times, and it is described by you today.
First, benzoic acid and allyl alcohol are used as raw materials, accompanied by a catalyst, and the esterification method is carried out. The key here lies in the choice of catalyst. Proton acids can be used, such as sulfuric acid, which has high catalytic activity and can promote the reaction to go faster. However, sulfuric acid is highly corrosive, which requires strict equipment, and has many side reactions, and the product separation is complicated. Solid acids can also be used, such as p-toluenesulfonic acid, which is weak in corrosiveness, easy to separate, and can be reused, which is very popular. When reacting, controlling the temperature, material ratio and reaction time are all key. If the temperature is too high, side reactions will occur frequently; if it is too low, the reaction will be slow. Improper material ratio also affects the yield. If the time is insufficient, the reaction will not be completed; if it is too long, it will consume resources.
Second, benzoate and allyl halide are used as raw materials, and the nucleophilic substitution reaction is carried out under alkaline conditions. The choice of base is crucial. Common bases, such as sodium hydroxide, potassium carbonate, etc. Sodium hydroxide has strong alkalinity and high reactivity, but it is easy to cause halide hydrolysis. Potassium carbonate is slightly less alkaline, which can reduce the risk of hydrolysis. In the reaction system, the choice of organic solvents also affects the reaction. Commonly used ones include acetone, acetonitrile, etc., depending on the solubility of the reactants and products.
Third, using benzaldehyde and allyl malonate as raw materials, the target product can be obtained through Knoevenagel condensation reaction. This reaction requires weak acid catalysis, such as acetic acid, and the reaction conditions are mild. However, the raw material benzaldehyde is easy to oxidize, and caution is required when storing and using it. During the reaction process, pay attention to removing water, because the existence of water, the adverse reaction is positive.
All this synthesis method has advantages and disadvantages. In practical application, when the availability of raw materials, cost considerations, product purity requirements, etc., choose carefully.

3,5-Diethyltoluene ether is an organic compound. Its physical and chemical properties are quite characteristic, as follows:
** 1. Physical properties **
1. ** Appearance and characteristics **: At room temperature, it is mostly a colorless to light yellow transparent liquid. It is clear in appearance and has no visible impurities. It visually gives people a sense of purity.
2. ** Smell **: It emits a unique aromatic smell. This aroma is relatively mild and non-pungent. In a specific environment, it can add a pleasant atmosphere to the air.
3. ** Boiling point **: The boiling point is about in a certain range, because the exact value will be affected by external conditions such as air pressure, roughly around [X] ° C. This boiling point characteristic determines that it will undergo a phase transition at a specific temperature during the heating process.
4. ** Melting point **: The melting point is relatively low, about [X] ° C, which means that it is stable and remains liquid at room temperature or slightly higher than room temperature.
5. ** Solubility **: It shows good solubility in organic solvents such as ethanol, ether, etc., and can be mixed uniformly with it; however, it has poor solubility in water. Due to the hydrophobic properties of its molecular structure, it is difficult to blend with water, and it is prone to stratification when the two are mixed.
6. ** Density **: The density is about [X] g/cm ³, which is slightly lower than the density of water, so if mixed with water, it will float on the water surface.
** Second, chemical properties **
1. ** Stability **: In conventional environmental conditions, 3,5-diethyltoluene ether has good chemical stability and is not easy to decompose or other violent chemical reactions on its own. In case of high temperature, open flame or strong oxidant, the stability will be affected.
2. ** Oxidation reaction **: Oxidation reaction can occur with oxidant under suitable conditions. For example, under specific catalyst and temperature and pressure conditions, some groups on the benzene ring may be oxidized to form corresponding oxidation products, which has certain application value in the field of organic synthesis.
3. ** Substitution Reaction **: Due to the presence of the benzene ring in its molecular structure, the hydrogen atom on the benzene ring can be replaced by other atoms or groups. For example, under the action of a specific catalyst, it can undergo a substitution reaction with halogenated hydrocarbons, introducing halogen atoms on the benzene ring, and then deriving a variety of compounds with different properties, broadening its application path in materials, medicine and other fields.

In today's market, the price of 3,5-diethoxybenzoic acid is quite difficult to put into words. Its price often changes due to various reasons, such as the price of raw materials, the difficulty of craftsmanship, the urgency of supply and demand, and the rise and fall of the market.
