Chemical Properties of 300KG 92-87-5 4,4’-Bianiline C12H12N2

Basicity of Aniline: Aniline is a weak base in nature. Its pKa value is around 4.6. It's basicity is lower than aliphatic amines due to the electron-withdrawing nature of benzene ring that decreases the availability of lone pair of electron on N atom for protonation.

 

Nucleophilic: The lone pair on the N atom of aniline make aniline to be attack by electrophiles.

 

Oxidation-sensitive: Undergoes oxidation in strong acidic conditions and form unwanted side products.

Uses

 

 

Trimethoxysilylpropanethiol is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. Trimethoxysilylpropanethiol is a clear, colorless to light yellow liquid with a slightly mercaptan odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

 

Applications:
Trimethoxysilylpropanethiol can be used as coupling agent to improve the adhesion of sulfur cured elastomers (polysulfide, polyurethane sealants) to inorganic fillers (such as silica, clay, glass, mica and talc etc.), fiberglass and surfaces. Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cable insulation also can be produced with lower silane loadings.
Used to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time.
Used as a pretreatment on minerals or added at the time of compounding.
Used to improve low-rolling resistance in silica-reinforced tire tread compounds.
