叔丁基二苯基甲氧基硅烷 - Introduction
tert-butyldiphenylmethoxysilane(tert-butyldiphenylmethoxysilane) is an organosilicon compound with the chemical formula C20H26OSi. Its properties are as follows:
1. appearance: colorless or light yellow liquid.
2. Boiling point: about 225-230°C.
3. density: about 1.01-1.03g/cm³.
4. Solubility: Soluble in most organic solvents, such as alcohols, ethers and aromatic hydrocarbons.
The main uses of the tert-butyldiphenylmethoxysilane are as follows:
1. as a siloxane coupling agent for the modification of organic polymer materials, such as coatings, adhesives, sealants and flexible plastics.
2. used as chemical intermediates, can participate in a variety of organic synthesis reactions, such as catalytic chain ring reaction and synthesis of silicon pyrimidine.
the common preparation method is to obtain tert-butyl diphenyl methanol by methylating diphenyl methanol (α,α-diphenyl ethanol), and then to obtain tert-butyldiphenylmethoxysilane by silicon substitution reaction with chloromethylmethanol.
About safety information:
1. tert-butyldiphenylmethoxysilane irritating to skin and eyes, use should pay attention to protective measures.
2. Avoid inhaling aerosols or vapors and operate in a well-ventilated place.
3. If you accidentally swallow or come into contact with large amounts of tert-butyldiphenylmethoxysilane, seek medical attention immediately.
