TRIS(TERT-BUTOXY)SILANOL - Introduction
Tri-t-butoxysilanol (TBOS for short) is an organic silicon compound. Its chemical formula is [(CH3)3CO]3SiOH, and it consists of a silicon atom connected to three tert-butoxy groups and one hydrogen atom.
The nature of TBOS is as follows:
-Appearance: TBOS is a colorless and transparent liquid.
-Melting point and boiling point: The melting point of TBOS is about -65 ° C, and the boiling point is about 110 ° C.
-density and solubility: TBOS has a density of about 0.87 g/cm ^ 3 and is slightly soluble in water. It is soluble in organic solvents such as ethers, alcohols and ketones.
TBOS has a wide range of applications in the chemical industry and materials science:
-Crosslinking agent of silicone rubber: TBOS can react with the hydrogenated silicon group in silicone rubber to form a crosslinked structure, thereby enhancing its strength and heat resistance.
-Synthesis of silicone polymers: TBOS can be used as raw materials for silicone polymers, such as the preparation of silicone rubber, silicone resin and silica gel.
-Surface treatment agent: TBOS can be used to treat the surface of materials such as glass, metal and plastic to improve their water resistance and corrosion resistance.
-Sealant formulation: TBOS can be used to prepare high-temperature and chemical-resistant sealants for applications in construction, automotive and electronics industries.
-Other applications: TBOS can also be used for the packaging of electronic devices, the preparation of rubber waterproof coatings, etc.
The preparation method of TBOS is mainly obtained by reacting Tris-tert-butylchlorosilane with water. Since TBOS is slightly soluble in water, the reaction process is usually carried out in an organic solvent, such as dimethylformamide, dichloromethane, etc.
Regarding the safety information of TBOS, the following points need to be noted:
-Because TBOS is irritating to the skin and glasses, wear protective glasses and gloves when using it, and avoid contact with skin and eyes.
- TBOS has the danger of explosion in high temperature environment, so it should be kept away from open flame and high temperature.
-When using or storing TBOS, avoid contact with harmful substances such as oxidants and strong acids to prevent dangerous chemical reactions.
-When using TBOS in a closed environment, ensure good ventilation to prevent its vapor from accumulating beyond the allowable concentration.
When using TBOS, you must pay attention to safety and operate in accordance with the safety operating procedures for chemicals. If necessary, it is recommended to use it under the guidance of professionals.
