| | Triethoxyoctylsilane Usage And Synthesis |
| Description | Triethoxyoctylsilane is a monomeric medium-chain alkylfunctional silane. It is a clear colourless liquid and soluble in common non-polar organic solvent.
Triethoxyoctylsilane can be used as a surface modifier to generate hydrophobicity (e.g. on concrete, glass, inorganic pigments, or mineral fillers).
When diluted with an appropriate solvent, it can be used in the formulation of water repellent products. Upon proper application, the formulated product will penetrate and provide water repellency by chemically reacting with the cementitious substrate. Treated substrates are hydrophobic and retain their original appearance.
| | Chemical Properties | Colorless transparent liquid | | Uses | Triethoxy(octyl)silane is a hydrophobization agent used to limit coalescence in solid-stabilized emulsions. | | Definition | ChEBI: Octyltriethoxysilane is an organosilicon compound. | | General Description | Triethoxy(octyl)silane (TEOS) is an alkoxide organosilane with four ethyl ester sidechains. It is used as a self-assembled monolayer and provides a hydrophobic coating with low surface energy. The water contact angle is in the range of 150-170°. | | in vivo | Triethoxyoctylsilane (10 mg/kg, intratracheal instillation, single dose) does not induce significant lung toxicity in rats, only transient and reversible inflammatory response | Animal Model: | Crl:CD (SD)IGS BR rats exposed to TESO-coated TiO2 particles[1] | | Dosage: | 2 mg/kg and 10 mg/kg | | Administration: | Intratracheal instillation, single dose, followed by monitoring at 24 hours, 1 week, 1 month, and 3 months | | Result: | Induced transient pulmonary inflammation (10 mg/kg), characterized by increased neutrophils in BAL fluid, which resolved completely within 1 week, with no significant lung toxicity. |
