What is trimethoxysilane?
What is trimethoxysilane?
Triethoxysilane is an organosilicon compound with the formula HSi(OC2H5)3. It is a colourless liquid used in precious metal-catalysed hydrosilylation reactions.
What is the function of APTES?
(3-Aminopropyl)triethoxysilane (APTES) is an aminosilane frequently used in the process of silanization, the functionalization of surfaces with alkoxysilane molecules. It can also be used for covalent attaching of organic films to metal oxides such as silica and titania.
What is an aminosilane?
Description. Silanamine is an N-silyl compound that is silane in which a hydrogen is substituted by an amino group.
Is APTES hydrophilic?
Subsequent treatment with APTES swaps surface functional groups for the hydrophilic, amine carrying molecule . After plasma cleaning and APTES treatment, thermoplastics are bonded to PDMS. These microfluidic devices retain their hydrophilicity for years.
Does silane have hydrogen bonding?
Silane, also called Silicon Hydride, any of a series of covalently bonded compounds containing only the elements silicon and hydrogen, having the general formula SinH2n + 2, in which n equals 1, 2, 3, and so on. The silanes are structural analogues of the saturated hydrocarbons (alkanes) but are much less stable.
How do you make Aptes solution?
All Answers (1) You can mix 200 μL APTES with 9.8 mL of 95% EtOH (total volume 10 mL). It is better to use a freshly prepared solution.
What is the standard state of triethoxysilane?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). (3-Aminopropyl)triethoxysilane ( APTES) is an aminosilane frequently used in the process of silanization, the functionalization of surfaces with alkoxysilane molecules.
Which is more toxic trimethoxysilane or silane?
Trimethoxysilane appears as a colorless liquid. Slightly soluble in water and denser than water. Hence floats on water. Very toxic by ingestion, inhalation or skin absorption. May also be corrosive to skin and eyes. Conformer generation is disallowed since MMFF94s unsupported atom valence InChI=1S/C3H9O3Si/c1-4-7 (5-2)6-3/h1-3H3
What are the symptoms of exposure to triethoxysilane?
Signs and Symptoms of Triethoxysilane Exposure: Signs and symptoms of acute exposure to triethoxysilane may include irritation of the eyes, skin, mucous membranes, and respiratory tract. Also, severe ocular burns, headache, and anesthetic effects may be noted.
When does triethoxysilane react with water to form ethanol?
