What are the main uses of 3-methoxytrifluorotoluene?

3-Aminoethoxyltriethoxysilane has its important use in many fields.

In the field of construction, it can be used as a protective agent for concrete. Because it can chemically react with the hydroxyl groups on the surface of concrete, a strong and hydrophobic siloxane network structure is formed. This structure is like a protective armor for concrete, which can effectively resist the intrusion of aggressive media such as water and chloride ions, improve the durability of concrete, and make it stable in harsh environments for a long time; without hindering the respiration performance of concrete, water vapor can escape normally to avoid structural damage caused by the accumulation of water vapor inside. Such as a high-rise building by the sea, protected by this material, it can resist seawater erosion for many years and stand still.

In the field of composites, 3-aminoethoxy-triethoxysilane is often used as a coupling agent. Composite materials are mostly composed of a matrix and a reinforcement, but the properties of the two are very different and the interfacial bonding force is weak. The siloxy group at one end of the silane coupling agent molecule can be hydrolyzed to form silanol, which can then condensate with the hydroxyl group on the surface of the inorganic reinforcement to form a covalent bond; the amino group at the other end can chemically react with the organic matrix or form a hydrogen bond, thus building a bridge between the inorganic and organic phases and enhancing the interfacial bonding force between the two. Taking glass fiber reinforced plastics as an example, after being treated, the glass fiber and the plastic matrix are tightly bonded, and the mechanical properties of the composite material are greatly improved, and the tensile strength and flexural strength are significantly enhanced. < Br >
In the paint industry, it is also quite useful. When added to the paint, it can react with the resin in the paint and the surface of the substrate, enhancing the adhesion between the paint and the substrate. When applied to the metal surface, it can improve the bonding force between the paint film and the metal, make the paint film not easy to fall off and peel, prolong the service life of the coating, and improve the water resistance and corrosion resistance of the paint. Such as the paint for the car shell, after adding this substance, it can still maintain good appearance and protective performance in the face of sun, rain and various complex environments.

What is the production method of 3-methoxytrifluorotoluene?

To prepare 3-aminotriethoxysilane, the method is as follows:
Take trichlorosilane first, place it in a low temperature environment, and slowly inject ethanol. During this period, you must observe the reaction situation, control its temperature, and ensure that the reaction is stable and orderly. When ethanol and trichlorosilane are combined in a suitable phase, the intermediate of ethoxysilane is obtained. The corresponding formula is roughly as follows: $SiHCl_3 + 3C_2H_5OH\ longrightarrow Si (OC_2H_5) _3Cl + 3HCl $. This step must prevent the gas of HCl from escaping, and it is appropriate to have a collection device.

Next, the obtained intermediate is co-placed with liquid ammonia in a pressure-resistant vessel, close to its mouth, and gradually heated to an appropriate degree. Ammonia and the chlorine atom in the intermediate should be substituted, and the nitrogen atom of ammonia is substituted for chlorine and connected to silicon to produce 3-aminotriethoxysilane. The formula should be as follows: $Si (OC_2H_5) _3Cl + 2NH_3\ longrightarrow Si (OC_2H_5) _3NH_2 + NH_4Cl $. After the reaction is completed, the contents of the container are cooled, and the ammonium chloride precipitate generated is removed. The product is purified by distillation to obtain pure 3-aminotriethoxysilane. < Br >
The first step in making this is to control the temperature so that all steps of the reaction are smooth; the second is to dispose of it properly when the gas escapes and precipitates, so as not to contaminate the product, in order to obtain the best purity of 3-aminotriethoxysilane.
