The physical properties of (diethylamino) ethyl silicate are as follows:
Its outer surface is usually a transparent liquid with low viscosity, good flow resistance, and can flow freely under normal conditions. Smell it, there is a special smell, but the smell is not pungent and can be tolerated.
Its density is slightly smaller in water. If it is on water, it can be floated on the water surface. The boiling properties of this compound are special. Under a specific force, it can be boiled to a certain extent. This property makes it specific in operations such as adding steam.
In terms of solubility, (diethylamino) ethyl silicate can be more soluble and miscible, such as ethanol, ether, etc., and can form a homogeneous mixture. However, the solubility in water is limited. Generally, it is completely miscible in water, and this property depends on the fundamental properties contained in its molecules.
Furthermore, its performance is also worth noting. Under normal conditions, it has a certain speed, which can slow down to the surrounding air. And because of its performance, if it does not exist in dense air, it may increase the evaporation degree of air.
Therefore, the physical properties of (diethylamino) ethyl silicate play an important role in the application of chemical industry, materials and other fields, affecting its various chemical reactions and the results of material development.

The chemical properties of diethylamino siloxy ethyl silicate are quite unique. This substance is hydrolytic and can slowly react with water in a water environment. Due to the activity of silicon-oxygen bonds in the molecule, when exposed to water, the hydroxide of the water molecule can attack the silicon atom, causing the silicon-oxygen bond to break, and then the corresponding silanol and ethanolamine products are formed.
And it has a tendency to polymerize. The hydrolyzed silanol groups can undergo condensation reactions with each other, and through the process of dehydration or dealcoholization, siloxane bonds are formed, and then more complex polymer structures are constructed. This property is of great significance in the preparation of organic-inorganic hybrid materials or silicon-based coatings.
In addition, it has good compatibility with a variety of organic compounds. Due to the existence of ethylamino in the molecule, it is endowed with certain organic affinity, which can be combined with many organic compounds containing active groups, such as alcohols, acids, amines, etc., through chemical bonding or physical action, so as to realize the modification of the surface of the material, or to improve the interfacial force between different phases in the blending system.
In addition, its thermal stability is also considerable. In the moderate temperature range, the molecular structure can be maintained stable without significant decomposition or chemical changes. This makes the substance potentially valuable for applications in high temperature environments, such as high temperature coatings and the preparation of heat-resistant composites.

Diethylamino siloxy ethyl silicate is often used in many fields, and its main uses are quite extensive.
In the field of material surface treatment, this substance has a significant effect. Due to its unique chemical structure, it can react with the surface of the material to form a dense and excellent protective film. For example, when used on the surface of metal materials, it can greatly enhance the corrosion resistance of metals. Metals are vulnerable to oxidation and corrosion in the natural environment. After being treated with diethylamino siloxy ethyl silicate, it can build a protective barrier on the metal surface, effectively blocking the contact of aggressive substances such as oxygen and moisture with metals, thereby prolonging the service life of metal materials. It is of great significance in construction, machinery manufacturing and other industries.
In the coatings and paints industry, this substance is also an important component. It can be integrated into the coating system as an additive to significantly improve the adhesion and weather resistance of the coating. Adhesion is a key element for the coating to play a good role in protection and decoration. Diethylamino siloxy ethyl silicate can promote the coating to bond more closely with the surface of the coated object and prevent the coating from falling off. At the same time, it enhances the weather resistance of the coating, so that it can maintain color and performance stability for a long time under natural conditions such as light and wind and rain, reduce fading, chalking and other phenomena, and is widely used in building exterior wall coatings, automotive coatings, etc.
In the preparation of composite materials, diethylamino siloxy ethyl silicate also plays an important role. It can be used as a coupling agent to enhance the compatibility between inorganic fillers and organic substrates. Composite materials are composed of materials with different properties, and poor compatibility between inorganic fillers and organic substrates is prone to performance degradation. This substance can build a "bridge" between the two and improve the comprehensive properties of composites, such as strength and toughness, etc. It is widely used in aerospace, automotive industry and other fields that require strict material properties.

To prepare 3 - (diethylamino) benzaldehyde, the following ancient methods can be used.
First, benzaldehyde is used as a base to make it condensate with diethylamine under appropriate conditions. In the reactor, put an appropriate amount of benzaldehyde and diethylamine, and add an appropriate amount of catalyst, such as acidic catalyst or basic catalyst, depending on the specific reaction mechanism. Adjust the reaction temperature and pressure to maintain a certain reaction time. Under acidic conditions, it may promote the nucleophilic addition reaction; under alkaline conditions, it can also promote the condensation of the two. After the reaction is completed, the product can be purified by distillation and extraction to obtain 3 - (diethylamino) benzaldehyde.
Second, benzene derivatives can also be used as starting materials. Appropriate substituents, such as halogen atoms or nitro groups, are introduced at specific positions in the benzene ring. Take the nitration reaction as an example, benzene is co-heated with mixed acids (a mixture of concentrated sulfuric acid and concentrated nitric acid), and nitro is introduced into the benzene ring. Then the nitro group is converted into an amino group through a reduction reaction. Then the amino-containing benzene derivative interacts with halogenated ethane to form diethylamino-substituted benzene derivatives. Finally, the aldehyde group is introduced at another specific position in the benzene ring through a specific oxidation reaction, which can be achieved by mild oxidation reagents, such as the mixed system of manganese dioxide and sulfuric acid, or by the Vilsmeier-Haack reaction. In the Vilsmeier-Haack reaction, the Vilsmeier reagent formed by phosphorus oxychloride and N, N-dimethylformamide reacts with benzene derivatives to introduce an aldehyde group, and then after subsequent treatment, 3 - (diethylamino) benzaldehyde can be obtained.
Third, or by means of the Grignard reagent method. First prepare a halogen containing diethylamino, react with magnesium chips in anhydrous ether and other solvents to form a Grignard reagent. Then react the Grignard reagent with compounds containing aldehyde precursors, such as with appropriate benzoates or formyl halides. After the reaction is completed, the target product 3 - (diethylamino) benzaldehyde can be obtained through hydrolysis and other steps. The conditions of each step of the reaction need to be carefully adjusted to achieve higher yield and purity.

3 - (diethylamino) benzaldehyde oxime chloride needs to pay attention to many matters during storage and transportation.
First, it is related to storage. A cool, dry and well-ventilated place should be chosen. This is because the substance may be sensitive to temperature and humidity, high temperature, humid environment, or cause its properties to change, and even cause chemical reactions. The storage place must be kept away from fire and heat sources to prevent the risk of fire and explosion. Because it may be flammable, it is flammable and explosive in case of open flame and hot topic. It should also be stored separately from oxidants, acids, bases, etc., and must not be mixed. Because these substances come into contact with it, or react violently, endangering safety.
Second, as for transportation. Be sure to ensure that the packaging is complete and sealed before transportation. If the packaging is damaged, the substance leaks, or causes environmental pollution, which also poses a threat to the safety of transporters. During transportation, it is necessary to strictly abide by relevant transportation regulations and choose appropriate transportation tools. Do not mix with contraindicated substances to prevent interaction during transportation. Transport personnel also need to be familiar with the characteristics of the substance and emergency treatment methods. If there is a leakage during transportation, it can be disposed of in time and properly.
And when handling, it should be handled lightly to avoid damage to the packaging and containers. Because it may cause danger when it is hit or shaken violently. Only by being careful in the storage and transportation process and paying attention to the above things can the safety of the storage and transportation of 3 - (diethylamino) benzaldehyde oxime chloride be guaranteed to the greatest extent.
