The main use of 1-hydroxyl-3- (triethoxy) silicon is to play a key role in many fields.
In the construction field, it can be used as a building waterproofing agent. Due to its unique chemical structure, it can chemically react with the surface of building materials to form a tight waterproof film. This film acts as a strong barrier, which can effectively block moisture penetration, greatly enhance the water resistance of buildings, and prolong the service life of buildings. It can be applied to moisture-prone parts such as roofs and basements.
In the paint industry, it is an extremely important additive. After adding paint, it can significantly improve the adhesion of the paint. By interacting with the surface of the substrate, the paint can be more firmly bonded to the surface of the object and is not easy to fall off. At the same time, it can also improve the weather resistance of the coating, so that it can maintain good performance for a long time in harsh environments such as wind and sun, climate change, etc., and is not easy to fade and powder.
Furthermore, in the preparation of composite materials, 1-hydroxyl-3- (triethoxy) silicon also plays an important role. As a coupling agent, it can enhance the interfacial bonding force between different materials. For example, in glass fiber reinforced plastics, one end can react with the hydroxyl group on the surface of the glass fiber, and the other end can be crosslinked with the resin matrix, so that the glass fiber and the resin are closely connected, thereby improving the mechanical properties of the composite material, such as strength and toughness.
In the field of electronic packaging materials, it can improve material properties. It can improve the adhesion between packaging materials and electronic components and ensure that electronic components are firmly connected in complex environments. In addition, it helps to improve the moisture and heat resistance of packaging materials, ensure the normal operation of electronic equipment in high temperature and high humidity environments, and reduce the probability of electronic failure due to environmental factors.
From this perspective, 1-hydroxyl-3- (triethoxy) silicon has shown important value in many fields such as construction, coatings, composites and electronic packaging due to its unique chemical properties, providing strong support for the development of various industries.

The physical properties of 1-hydroxyl-3- (triethoxy) silicon are as follows:
This substance may be a liquid under normal conditions. Looking at its color, it is clear and transparent, just like morning dew, pure and free of variegated stains. The smell of its smell, although not fragrant, but also not pungent and intolerable smell, only slightly specific smell, light but not strong, if there is no time, it can be felt unique.
When it comes to density, it is slightly lighter than water. If placed in water, it is like a light boat overflowing in blue waves and slightly floating on it. Its boiling point is not low, and a higher temperature is required to turn it from liquid phase to gas phase, just like if you want to climb a peak, you must climb it with difficulty. This property allows it to maintain a relatively stable liquid state at ordinary temperatures.
Its solubility is also unique, and it can be fused with some organic solvents, just like a confidant meeting, and the mutual solubility is seamless. In alcohol solvents, it can be evenly dispersed, regardless of each other, showing good mutual solubility. However, in water, its solubility is quite limited, only a small amount can be dissolved, just like a pearl entering water, and it is difficult to completely disappear.
As for its surface tension, it is relatively low, just like a gentle thread, making it difficult to form a tight surface binding. This property allows the substance to be easily spread on the surface of some materials, such as oil paint on canvas, which can be evenly extended to cover all aspects.
In addition, the viscosity of 1-hydroxy- 3- (triethoxy) silicon is moderate, and it does not flow unimpeded like dilute water, nor does it stagnate and difficult to move like concentrated glue. When tilted, its flow speed is relatively smooth, like a mountain stream, leisurely and slow, this viscosity characteristic makes it easy to operate and handle in many process applications.

In this compound, 1-naphthalene group provides a large aromatic conjugate system, which can enhance the stability of the molecule. The structure of the naphthalene ring is relatively rigid, which makes the entire molecular skeleton stable to a certain extent. The introduction of the 3 - (trifluoromethoxy) phenyl group part, trifluoromethoxy group brings special electronic effects. The fluorine atom has a large electronegativity, and the electron cloud density on the benzene ring decreases through the induction effect, thereby affecting the electron distribution of the molecule as a whole. This change in the electron cloud distribution has an impact on the chemical stability of the molecule to a certain extent. From the perspective of spatial structure, trifluoromethoxy occupies a certain space and interacts with naphthalene group to form a relatively stable spatial conformation.
However, the stability of this compound is not absolute. Under certain chemical environments, such as encountering strong oxidizing agents, strong acids, strong bases, etc., its chemical properties may change. Strong oxidizing agents may attack the regions with higher electron cloud density on the naphthalene ring, initiating oxidation reactions and destroying the conjugated structure of the naphthalene ring. Strong acids or strong bases may react with certain groups in the molecule, such as the oxygen atom in the trifluoromethoxy group may protonate with the strong acid, which in turn affects the stability of the molecule. However, under mild conditions, such as at room temperature, room pressure and without the action of special chemical reagents, 1-%E7%A1%9D%E5%9F%BA-3-%28%E4%B8%89%E6%B0%9F%E7%94%B2%E6%B0%A7%E5%9F%BA%29%E8%8B%AF can maintain relatively stable chemical properties.

To prepare 1-cyano-3- (trifluoromethoxy) benzene, the method is as follows:
First take trifluoromethanol, in an appropriate reactor, at a low temperature, slowly drop into a solution containing alkali. This base can be selected from potassium hydroxide and the like, stir well to form a solution of trifluoromethoxy negative ions.
Take another halogenated benzonitrile, such as 3-halogenated benzonitrile, the halogenated atom can be chlorine, bromine, etc. Put this halogenated benzonitrile into the above solution containing trifluoromethoxy negative ions, warm it to a moderate temperature, such as 60-80 degrees Celsius, and carry out nucleophilic substitution reaction. During the reaction, it is necessary to continue stirring to allow the reactants to fully contact and accelerate the reaction process. After several hours of reaction, monitor by thin layer chromatography or gas chromatography until the reaction is complete.
After the reaction is completed, the reaction solution is cooled, and the excess bases in it are neutralized with dilute acid, such as hydrochloric acid. Then the organic phase is extracted with an organic solvent, such as dichloromethane, to separate the organic phase. Then the organic phase is dried with anhydrous sodium sulfate to remove the moisture. After that, the organic solvent is removed by distillation under reduced pressure to obtain a crude product of 1-cyano-3- (trifluoromethoxy) benzene.
To obtain a pure product, the crude product can be subjected to column chromatography, using silica gel as the stationary phase, and an appropriate proportion of petroleum ether and ethyl acetate mixture as the mobile phase for separation and purification. Collect the fraction containing the target product, distillate again, and remove the mobile phase to obtain pure 1-cyano-3- (trifluoromethoxy) benzene.
Or you can use benzene as the starting material and nitrate it to obtain m-nitrobenzene. Then, in the presence of a specific catalyst, a trifluoromethylation reagent, such as sodium trifluoromethylsulfonate, is introduced to introduce a trifluoromethoxy group to obtain 3-trifluoromethoxy nitrobenzene. Then the reduction method, such as iron powder and hydrochloric acid as a reducing agent, reduces the nitro group to an amino group to obtain 3-trifluoromethoxy aniline. Then through diazotization reaction, interacting with cuprous cyanide and other reagents to replace the amino group with a cyano group, 1-cyano-3- (trifluoromethoxy) benzene can also be prepared. This method has its own advantages and disadvantages, and it needs to be selected according to the actual situation.

1-% cyano-3- (trifluoromethoxy) benzene is a highly toxic product, and many matters need to be paid careful attention during storage and transportation.
Bear the brunt, the storage place must be dry and well ventilated. If these highly toxic substances are placed in a humid place, or their properties are changed due to moisture erosion, and even cause chemical reactions, resulting in increased toxicity or other unstable factors. Where ventilation is poor, toxic gases can easily accumulate, posing a serious threat to the surrounding environment and personnel safety.
Furthermore, the storage temperature needs to be strictly controlled. Excessive or too low temperature should be avoided. Excessive temperature may cause it to evaporate and accelerate, and toxic gases overflow. Excessive temperature may cause it to solidify and crystallize, which will affect its stability and subsequent use and safety. Generally speaking, it is necessary to maintain a suitable temperature range according to its chemical characteristics.
When transporting, the packaging must be solid and reliable. Special packaging materials need to be used to ensure that during transportation, it will not be damaged and leaked due to bumps and collisions. The package should be clearly marked with its highly toxic properties and corresponding warning labels, so that transporters and related personnel can see it at a glance and treat it with caution.
The means of transportation should also be carefully selected and should not be mixed with other flammable, explosive and corrosive substances. Due to its highly toxic properties, once it interacts with other items, it is very likely to cause catastrophic consequences. During transportation, it is necessary to have a special person closely monitor it, keep track of its status in real time, and take appropriate measures immediately if any abnormality is detected.
Those who are involved in storage and transportation should be professionally trained and familiar with its characteristics, hazards and emergency treatment methods. Only in this way can the storage and transportation of 1-% cyano-3- (trifluoromethoxy) benzene be carried out to maximize the safety of personnel and the environment, and prevent accidents.
