Preparation Method
"On the Method of Preparation of Ethyl Silicate"
To make ethyl silicate, the raw materials and process must be clear. The raw materials are mainly silica and ethanol. The preparation process is as follows: First, the silica is finely ground to make it pure and fine particles. Then mix it with an appropriate amount of ethanol and put it into a special kettle. When heating up to the right heat, the process needs to be slow and uniform, and the temperature should not change suddenly.
When reacting, carefully control the temperature and wait for the two to fully blend and react. In the meantime, observe the change of its color and texture to judge the progress of the reaction. After the reaction is completed, the impurities are removed by a delicate separation method, leaving pure ethyl silicate.
In order to promote efficient output, an exquisite recycling mechanism is set up to re-enter the unreacted raw materials into the process, recycle and improve the yield. In this way, high-quality ethyl silicate products can be obtained.

Chemical Reactions & Modifications
"Taiyi Ingredients" has a saying: "The beauty of chemical modification lies in its modification. Today there is Tetraethyl Silicate, and its modification is especially coincidental. Tetraethyl Silicate, hydrolyzed in contact with water, generates silanol, which is controlled and orderly. And under certain conditions, it can be polymerized and intersected to form a solid solution, and its properties are high. This is because of the ethoxy activity of its molecules, which can be interacted with multiple groups. The function of its modification depends on the hardness and properties of the material. Therefore, Tetraethyl Silicate is used in the chemical field, and its special modification properties are inverse and effective. It is also useful.

What are the physical properties of tetraethyl silicate?
Tetraethoxysilane, also known as ethyl silicate, has the following physical properties:
This substance is a colorless and transparent liquid at room temperature, just like clear water, with a clear view. Its smell is unique, with an ether-like fragrance, and it smells refreshing.
Tetraethoxysilane has a slightly lighter density than water, about 0.934g/cm ³. It is placed in water, such as oil floating on the water surface. Its boiling point is quite high, reaching 165.5 ° C. It is not easy to boil quickly when heated, and it needs a hot topic to boil and vaporize. The melting point is very low, at -77 ° C. It is difficult to solidify under cold weather.
Its solubility is unique, and it can be arbitrarily miscible with various organic solvents such as ethanol, acetone, and benzene, and it blends seamlessly, just like water and emulsion. When it meets water, it reacts and hydrolyzes to form silicic acid and ethanol, which cannot coexist peacefully with water.
In addition, tetraethoxysilane is highly volatile and can evaporate slowly in air. If placed in an open container, its amount will gradually decrease. And its vapor is heavier than air and can spread to a considerable distance at a lower place.

What should be paid attention to when storing and transporting tetraethyl silane?
When storing and transporting tetraethyl silane, pay attention to many matters. This substance is volatile and flammable, so it is the first to be fireproof. Store in a cool and ventilated place, away from fire and heat sources, and the temperature should not be too high to prevent volatilization from intensifying or even triggering the risk of combustion.
When transporting, it is also necessary to strictly abide by relevant procedures. The packaging must be tight and firm to ensure that there is no risk of leakage. Because it may be irritating to the human body, the person handling it should wear suitable protective equipment, such as protective gloves, glasses, etc., to avoid touching the skin and eyes.
Furthermore, tetraethoxysilane is prone to react in contact with water or moisture, and the storage and transportation environment should be kept dry. The storage place should also be separated from oxidizing agents, acids, etc., because of their contact or dangerous reaction.
In short, when storing and transporting tetraethoxysilane, fire prevention, leakage prevention, moisture prevention, and isolation of incompatible substances should not be ignored, and they must be treated with caution.

What is the preparation method of tetraethyl silicate?
The preparation method of tetraethoxysilane (Tetraethyl Silicate) is not detailed in ancient books, but based on today's theory, there are about the following ways.
First, use silanol and ethanol as raw materials, add an appropriate catalyst to make the esterification reaction. The method is also to take an appropriate amount of silanol first, place it in a clean container, slowly inject ethanol, and the amount is determined according to the ratio of the two reactions. Then, add a little catalyst such as concentrated sulfuric acid or p-toluenesulfonic acid, both of which have strong catalytic energy and can promote the reaction speed. However, the amount of catalyst should not be too much, and more is easy to lead to side reactions. Compound with a constant temperature water bath for heating, control the temperature between 60 and 80 degrees Celsius, if the cap temperature is high, side reactions occur frequently; if the temperature is low, the reaction is slow. At this temperature, stir it to make the two fully mixed, and when the number of reactions, until the composition of the reaction solution does not change much, the crude product is obtained. After purification by distillation, the unreacted raw materials and by-products are removed, and the purer tetraethoxysilane can be obtained.
Second, it is prepared by reacting silicon tetrachloride with ethanol. Take silicon tetrachloride first, and slowly drop it into ethanol. Do not reverse, in case the reaction is too violent. During the reaction, hydrogen chloride gas escapes, so it should be done in a well-ventilated place, and a device for tail gas absorption should be set up to remove hydrogen chloride and prevent it from polluting the environment. This reaction also requires the help of a catalyst. Organic bases such as pyridine or triethylamine can be used, which can neutralize the hydrogen chloride generated by the reaction and shift the reaction equilibrium to the right. After the reaction is completed, the product is also separated by distillation to collect a fraction with an appropriate boiling point, which is tetraethoxysilane.
These two are common methods for preparing tetraethoxysilane. However, when preparing, the dosage of each substance and the reaction conditions need to be carefully adjusted to obtain a high-purity product.

What is the market price range for tetraethyl silicate?
The market price of tetraethoxysilane often varies depending on factors such as quality, purity, supply and demand, origin and manufacturer. In the current market, its price fluctuates roughly between tens of yuan and hundreds of yuan per kilogram.
If the quality is average and the purity is ordinary, the price may be relatively low for those used in common industrial fields, ranging from tens to more than 100 yuan per kilogram. However, for high-end fields such as electronics and optics, high-purity tetraethoxysilane, which requires strict purity and impurity content, is much more expensive, reaching hundreds of yuan per kilogram.
And the market supply and demand situation also has a great impact on the price. If the demand is strong and the supply is limited, the price tends to rise; conversely, if the market supply is sufficient and the demand is weak, the price may decline. The price of tetraethoxysilane produced by different origins and manufacturers also varies. Imported products may be relatively high due to brand and quality factors; some domestic products may be more affordable.
For more accurate prices, it is recommended to consult chemical product suppliers and distributors for details, or refer to the latest quotations on the chemical product trading platform.
