1、 Basic properties
The molecular formula of PTMS is C12H23O3Si4, with a molecular weight of 327.6512. It usually appears as a colorless or light yellow transparent liquid, with high chemical reactivity and thermal stability. At 25 ℃, its density is 0.88g/mL. In addition, PTMS also has a lower boiling point and a higher flash point, which give it unique advantages in chemical synthesis and material preparation.

In the molecular structure of PTMS, the phenyl group is connected to the methyl group in silane, forming a relatively stable chemical bond. Due to the high π - electron cloud density of phenyl groups, PTMS has a strong attraction to functional groups with strong electrophilicity, resulting in relatively high reactivity. Meanwhile, the three methoxy groups in silane also have high electrophilicity, further enhancing the chemical activity of PTMS.


2、 Synthesis method
There are various synthesis methods for PTMS, and a typical synthesis method is to react phenyltrimethoxysilane with tetramethyldihydrodisiloxane and other raw materials under specific conditions. In the specific synthesis process, it is necessary to control factors such as reaction temperature, pressure, and molar ratio of raw materials to obtain high-purity PTMS products. In addition, PTMS can also be synthesized through other chemical methods such as catalytic reactions, addition reactions, etc. The specific method chosen depends on production requirements and raw material sources.

3、 Application Fields
PTMS has wide application value in multiple fields due to its unique chemical properties and structural characteristics.

Materials Science: PTMS can be used as a raw material for the preparation of graft copolymers, polymers, nanomaterials, etc., and its properties can be improved through chemical modification. For example, introducing PTMS into polymers can significantly improve their heat resistance, weather resistance, and mechanical strength.
Chemical Engineering: In chemical engineering, PTMS can be used as a crosslinking agent to prepare polymer materials such as addition molded silicone rubber, phenyl silicone rubber, and phenyl silicone resin. These materials have a wide range of applications in fields such as electronics, electrical engineering, aerospace, etc.
Drug preparation: PTMS also has certain applications in drug preparation. It can be used as one of the raw materials for synthesizing drug molecules, introducing specific functional groups through chemical reactions to alter the biological activity and pharmacological effects of drugs.
Surface modification: PTMS can also be used as a surfactant for surface modification and functionalization of various materials. By changing the chemical properties of the material surface, its compatibility and adhesion with other substances can be improved, thereby expanding the application range of the material.


4、 Future prospects
