To prepare 3,5-bis (chloromethyl) -benzyl benzoate (1:1), there are various methods for its synthesis. In this synthesis, benzyl benzoate is first used as a group to interact with chloromethylation reagents. The method of capping chloromethylation is often carried out with polyformaldehyde, hydrogen chloride and zinc salts. In this reaction system, the benzene ring of benzyl benzoate is affected by reagents, and chloromethyl is introduced, which can lead to the formation of 3,5-bis (chloromethyl) -benzyl benzoate.
Furthermore, benzoic acid can be chloromethylated first to obtain 3,5-bis (chloromethyl) benzoic acid, and then it can be estered with benzyl alcohol. This esterification method can be catalyzed by acids, such as concentrated sulfuric acid and p-toluenesulfonic acid, to promote the condensation of the two to form the target product.
Another way is to start with suitable aromatic hydrocarbons, first build 3,5-bis (chloromethyl) aromatic structure by chloromethylation, then introduce carboxyl groups through carboxylation reaction, and finally ester with benzyl alcohol.
When synthesizing, each method has its own advantages and disadvantages. Chloromethylation requires attention to the control of reagent ratio, reaction temperature and time. Improper ratio, temperature discomfort or wrong time can cause side reactions to cluster and yield to be reduced. In esterification, the amount of catalyst and the choice of reaction conditions are also crucial. Too much or too little catalyst can affect the reaction rate and equilibrium. Factors such as the purity and dryness of the reaction system will also affect the effectiveness of the synthesis. Careful consideration and careful operation are required to make the synthesis smooth and obtain the target product.

3,5-Bis (chloromethyl) -, succinic anhydride (1:1) This substance is related to the chemical industry. When storing and using it, there are several matters that need to be paid attention to.
The first storage method. This substance should be placed in a cool, dry and well-ventilated place. Because if it is in a warm and humid place, its properties may change. Moisture can easily cause its hydrolysis. If it looks like hydrolysis, the effect will be greatly reduced, and even harmful substances will be generated. Therefore, in the warehouse, the temperature and humidity should be strictly controlled. The temperature should not exceed 20 degrees Celsius, and the humidity should be maintained below 50%. And it should be kept away from fire and heat sources. In case of open flames or hot topics, there may be the risk of burning or exploding. It is lively and should be placed separately from oxidants, alkalis and other substances. It must not be mixed to prevent violent chemical reactions.
Secondary essentials of use. When using, be sure to take protective measures. Practitioners should wear special protective clothing, protective masks on their heads, and protective gloves on their hands to avoid contact with the skin and respiratory tract. If they accidentally touch the skin, they should immediately rinse with a lot of water, and then seek medical treatment; if they enter the eyes, they should immediately open the eyelids, rinse with flowing water or normal saline, and quickly go to the hospital for treatment. In the operation site, ventilation equipment must be complete to prevent the accumulation of harmful gases. Furthermore, the utensils used should be clean and dry to prevent impurities from mixing in and affecting their quality and reaction process. When using, it is advisable to follow the specified amount, and do not increase or decrease at will to ensure the accuracy and safety of the reaction. If there is any waste, it must not be discarded at will, and it must be properly disposed of according to relevant regulations to avoid defacement of the environment.
