What are the physical properties of Chloromethyl (Methyl) Dimethoxysilane
Chloromethyl (methyl) dimethoxysilane is a kind of organosilicon compound. Its physical properties have many characteristics.
Looking at its properties, under normal circumstances, it is a colorless and transparent liquid, clear like jade, which can be distinguished by light. Its smell is unique. Although it is not pungent or intolerable, it is also recognizable and leaves marks on the sense of smell.
When it comes to density, it is within a certain range and is slightly lighter than water. If placed in a water solution, it may float on it, such as a leaf flood wave. Its boiling point is also a specific value. When the temperature rises to the corresponding degree, it can be seen boiling and tumbling, and the gas rises.
The solubility of chloromethyl (methyl) dimethoxysilane is worth noting. In common organic solvents, such as ethanol, ether, etc., it can be well miscible with each other, just like water emulsion blending, indistinguishable from each other. However, in water, due to its structural characteristics, hydrolysis reactions are easy to occur, which is the key characteristic of its interaction with water. During hydrolysis, the silane bond breaks, and new compounds are gradually formed, with subtle changes.
Its volatility cannot be ignored. Under suitable temperature and humidity conditions, it can evaporate slowly, and molecules can escape from the surrounding space. The physical properties such as surface tension are also similar to those of the same kind of compounds, and they show different characteristics at the interface. In many fields such as material surface modification, this property may be effective.
Is Chloromethyl (Methyl) Dimethoxysilane Chemically Stable?
The chemical properties of chloromethyl (methyl) dimethoxysilane are quite stable. This substance contains silicon-oxygen bonds, and the silicon-oxygen bonds have high bond energy, which makes the molecular structure relatively stable. And the groups around its silicon atoms also contribute to its stability.
Under general environmental conditions, without specific chemical reaction conditions, chloromethyl (methyl) dimethoxysilane can maintain its own structure. Although its chloromethyl part has certain reactivity, it is not easy to react spontaneously without specific agents or conditions such as nucleophiles and strong bases.
As far as storage is concerned, under normal temperature and pressure, if properly stored in a sealed container, it is protected from water and moisture. Because it is more sensitive to water, it is easy to hydrolyze in contact with water, resulting in corresponding silanol and hydrogen chloride. However, in a dry and suitable environment, it can exist stably, and the chemical properties do not change significantly within a certain period of time. In short, chloromethyl (methyl) dimethoxysilane can be said to be stable under suitable conditions.
What is the preparation method of Chloromethyl (Methyl) Dimethoxysilane
To prepare chloromethyl (methyl) dimethoxysilane, the method is as follows:
First take an appropriate amount of methyl dichlorosilane and place it in a clean reactor. The reactor needs to be specially made, which can resist corrosion and can precisely control the temperature and stir. The kettle temperature is adjusted to a specific low temperature range with a precise method, about minus ten to zero degrees Celsius. This low temperature environment can effectively control the reaction rate, so that the reaction can proceed smoothly and avoid sudden violent reactions.
Then, at a very slow speed, add anhydrous methanol dropwise into the reactor. The dripping speed must be precisely controlled. If it is too fast, it is easy to cause the reaction to go out of control. If it is too slow, it will take too long and affect the efficiency. The molar ratio of methanol to methyl dichlorosilane needs to be prepared according to an accurate stoichiometric ratio, generally about two to one. This ratio can ensure that the reaction is sufficient and the product purity is high.
When adding dropwise, turn on the stirring device to allow the reactants to mix thoroughly. The stirring speed also needs to be moderate. If it is too fast, it is easy to splash out the material, and if it is too slow, the mixing will be uneven, which will affect the reaction effect. With the dropwise addition of methanol, the reaction occurs gradually, during which hydrogen chloride gas escapes.
In order to make the hydrogen chloride gas discharge in time, and at the same time prevent external water vapor from entering the reaction system, an efficient gas export device needs to be connected to the reaction kettle, and a suitable alkaline solution is used to absorb the escaped hydrogen chloride gas to prevent it from polluting
After the methanol is added dropwise, keep the reaction system at low temperature for a period of time to allow the reaction to proceed fully. This process takes about one to two hours. Then, slowly raise the temperature of the reactor to room temperature and maintain it for a period of time to ensure the complete reaction.
After the reaction is completed, the reaction product is post-processed. First, solid impurities that may exist are removed by filtration, and then the filtrate is distilled under reduced pressure. By precisely adjusting the distillation temperature and pressure, a fraction in a specific temperature range is collected. This fraction is chloromethyl (methyl) dimethoxysilane. After this step, a high-purity target product can be obtained.
What to pay attention to when storing and transporting Chloromethyl (Methyl) Dimethoxysilane
Chloromethyl (methyl) dimethoxysilane is an organosilicon compound. When storing and transporting, the following points should be paid attention to:
First, the storage environment is the most critical. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources. Because of its flammability, it is easy to burn in case of open flames and hot topics, so avoiding fire sources can greatly reduce the risk of fire. If the storage environment temperature is too high, or it will cause its volatilization to increase, the pressure will rise, and the danger of container rupture will be caused.
Second, it should be stored separately from oxidizing agents, acids, bases, etc., and must not be mixed. Because of its active chemical properties, contact with the above substances, or cause violent chemical reactions, and even explosions. For example, contact with acids, or cause the silane bond to break, generating harmful gases; reaction with alkalis may also change its chemical structure and release energy.
Third, the storage container must be well sealed. This compound is easy to hydrolyze, and the moisture in the air will cause it to hydrolyze, generating the corresponding silanol and methanol, which not only causes product deterioration, but also methanol is toxic and volatile, endangering the environment and personal safety. Therefore, sealed storage can block moisture intrusion and maintain its chemical stability.
Fourth, when transporting, it is necessary to ensure that the container is securely fixed to prevent collision and leakage. Once a leak occurs, chloromethyl (methyl) dimethoxysilane will react quickly in contact with water or humid air, generating irritating and corrosive gases that endanger transportation personnel and the surrounding environment. If it leaks on the ground, emergency measures should be taken immediately, such as absorbing it with inert materials such as sand and vermiculite to avoid its diffusion.
In short, the storage and transportation of chloromethyl (methyl) dimethoxysilane must strictly abide by relevant safety regulations and be cautious to ensure the safety of personnel and the environment.
