CAS 17146-09-7: (3-Phenylpropyl)dimethylchlorosilane

Chlorodimethyl(3-phenylpropyl)silane is an organosilicon compound that has been used as a catalyst in the ring-opening polymerization of alpha,beta-unsaturated esters. It has also been used to synthesize catecholamines by chlorination and sulfonation of phenylethylamine. Chlorodimethyl(3-phenylpropyl)silane is soluble in organic solvents such as ether, benzene, chloroform, and carbon tetrachloride and reacts with alkali metals to form Grignard reagents. The infrared spectrum of chlorodimethyl(3-phenylpropyl)silane shows absorption bands at 1750 cm−1 (C=S), 1630 cm−1 (C=O), 1425 cm−1 (C=C), 1265 cm−1 (CH), 1160 cm−1 (CH), 1090 cm−1

Aromatic Silane - Conventional Surface Bonding Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced concrete. A selection guide for hydrophobic silanes can be found on pages 22-31 of the Hydrophobicity, Hydrophilicity and Silane Surface Modification brochure.
