There are various ways to synthesize 3-chlorobenzylbenzyldiethoxysilylsuccinic anhydride, which are described in ancient methods. First, it can be started from benzyl chloride. First, take an appropriate amount of benzyl chloride, add an appropriate amount of magnesium chips in a suitable reactor, use anhydrous ethyl ether as a solvent, and slowly initiate a reaction at low temperature and protected by nitrogen flow to prepare Grignard's reagent. This process requires careful temperature control and does not overplay the reaction. After the Grignard reagent is prepared, it is added dropwise to an anhydrous ethyl ether solution dissolved in 3-chlorobenzaldehyde to maintain a certain number of reactions at a certain temperature, and an alcohol intermediate can be obtained. Subsequently, the intermediate is oxidized with a suitable oxidizing agent, such as Jones reagent, under appropriate conditions, and the alcohol group can be converted into a carboxylic group to obtain a carboxylic acid compound. Furthermore, take diethoxysilylsuccinic anhydride, mix the carboxylic acid compound obtained above with it, add an appropriate amount of catalyst, such as 4-dimethylaminopyridine (DMAP), and use dichloromethane as a solvent to react under mild heating conditions. In this reaction, the catalyst can effectively promote the condensation reaction of the two. After several times of reaction, 3-chlorobenzylbenzyldiethoxysilylsuccinic anhydride can be obtained by conventional separation and purification methods, such as column chromatography. Second, 3-chlorobenzoic acid can also be used as a starting material. First, 3-chlorobenzoic acid is co-heated with thionyl chloride to convert the carboxyl group into an acid chloride. This reaction is more violent, and careful operation is required, and attention is paid to the absorption of exhaust gas. After obtaining the acid chloride, it is reacted with a benzyl magnesium halide reagent (made of benzyl halide and magnesium chips in anhydrous ethyl ether) to obtain a ketone compound. Next, the ketone compound is reduced. Sodium borohydride isothermal and reducing agent can be used to react in an alcohol solvent to reduce the ketone group to an alcohol hydroxyl group. After that, the compound containing alcohol hydroxyl group and diethoxy silyl succinic anhydride are refluxed in toluene in the presence of concentrated sulfuric acid with catalytic amount, and the esterification reaction of alcohol and acid anhydride is catalyzed by concentrated sulfuric acid. After the reaction is completed, the target product 3-chlorobenzylbenzyldiethoxy silyl succinic anhydride can also be obtained through cooling, washing, drying and column chromatography. All synthesis methods have their own advantages and disadvantages, and they need to be carefully selected according to the actual availability of raw materials, the convenience of reaction conditions and the purity requirements of the product.

The impact of 3-chloropropylmethyl diethoxysilane on the environment is related to the creation of heaven and earth and all living things, and cannot be ignored. If this substance escapes in the atmosphere, its gas phase characteristics may interact with many meteorological elements. Under light, it may cause complex photochemical reactions, generate new active intermediates, interfere with the inherent chemical balance in the atmosphere, and may have adverse effects on air quality. If it flows into the water, its chemical structure may cause aquatic ecological disturbance. Microbial communities in the water bear the brunt, or their toxicity inhibits normal metabolism and reproduction, thereby disrupting the bottom structure of the food chain. Aquatic plants are also difficult to escape, and their photosynthesis, nutrient uptake or hindrance affect the self-purification ability of water bodies and ecological cycles. As for the soil environment, this silane substance may be adsorbed on soil particles, changing the physical and chemical properties of the soil. Affect soil aeration and water retention, hinder plant root growth and nutrient absorption. And it degrades slowly in the soil, accumulates for a long time or poses a potential threat to the entire terrestrial ecosystem. Its volatilized vapor, if inhaled by humans, or irritates the mucosa of the respiratory tract, causes discomfort and even lesions. Skin contact may also lead to adverse reactions such as allergies, which endanger human health. Therefore, when using 3-chloropropyl methyl diethoxysilane, we should adopt a prudent attitude, complete protective measures and proper handling procedures to reduce its harm to the environment and people, and create a harmonious coexistence between people and nature.
