Triethoxyisobutylsilane Chemical Properties, Uses, Production
Chemical Properties
Colorless clear liquid
Uses
It is used in a wide range of applications including silane coupling agent, silane adhesion promoter, silane hydrophobing agent, silane dispersing agent, silane cross linking agent, silane moisture scavenger, polypropylene catalyst, silicate stabilizer, polyurethane endcapper silane, silane drying agent, silane curing agent, silane reinforcer, silylating agent, silane reducing agent, silyl building blocks and synthons.
Flammability and Explosibility
Flammable
Synthesis
Using halogenated isobutane and active metal reaction to generate organometallic compounds, this organometallic compound because the metal atom is directly connected to carbon to form a polar covalent bond, carbon is the negatively charged end of the extremely strong Lewis base, can be taken from the substance with Lewis acidic proton or positively charged groups, such as the reaction with ethyl n-silicate, can be taken from Si(OCH2CH3)3, to generate isobutyltriethoxysilane.
