(PENTAFLUOROPHENYL)TRIETHOXYSILANE - Introduction

It is an organic silicon compound. Its chemical formula is C8H9F5SiO3, and its structure contains a silicon atom and three ethoxy groups, as well as a pentafluorophenyl group. The following is an introduction to its nature, use, preparation and safety information:

Properties: It is a colorless liquid, insoluble in water at room temperature, but soluble in organic solvents such as ethanol and ether. It has good stability and chemical inertness.

Uses: It is often used as an intermediate for organic silicon compounds. Because of its pentafluorophenyl group, it has good hydrophobicity and high temperature resistance, so it can be used to improve the interfacial properties and weather resistance of polymers, coatings, rubber and other materials.

preparation method: usually obtained by the reaction of pentafluorobenzene boric acid and triethoxysilyl chloride. The detailed steps of the specific preparation method require laboratory synthesis or special equipment production.

safety information: belongs to chemicals, should pay attention to safety when using. It is irritating and may cause irritation and damage to the eyes, skin and respiratory system. Wear protective glasses, gloves and respiratory protective equipment to avoid contact with skin and eyes. Avoid inhaling its vapors or dust. During use or storage, please pay attention to fire and explosion prevention, and ensure a well-ventilated working environment. In case of inhalation or contact, immediately remove contaminated clothing from the source, flush the affected area with plenty of water, and seek medical advice and treatment.
