NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of high-quality chemical raw materials, including specialty silanes essential for advanced material science and various industrial applications. Our portfolio features key intermediates and modifiers, such as 3-Phenylpropyldimethylchlorosilane, identified by its CAS number 17146-09-7.

This particular compound, 3-Phenylpropyldimethylchlorosilane, is a chlorosilane characterized by the chemical formula C11H17ClSi. It presents as a clear liquid, ranging in color from colorless to light yellow, and typically boasts a purity level of a minimum of 95%. Its distinctive molecular structure, featuring both a reactive chlorosilyl group and a phenylpropyl organic moiety, makes it exceptionally suitable for specific chemical transformations and surface functionalizations.

One of the primary and most significant applications of 3-Phenylpropyldimethylchlorosilane is its use as a modifier for surfaces rich in hydroxyl (-OH) groups. Materials such as glass, metal oxides, and particularly various forms of silica, including precipitated silica, fumed silica, and crucially, nanosilica, possess abundant surface hydroxyls. These surface groups are highly reactive towards chlorosilanes like 3-Phenylpropyldimethylchlorosilane.

The modification process typically involves the reaction of the chlorosilyl group with the surface hydroxyls, releasing hydrogen chloride (HCl) as a byproduct. This reaction creates a stable, covalent bond between the silicon atom of the silane and the oxygen atom on the material surface. The organic part of the silane—in this case, the phenylpropyl chain—is then grafted onto the surface. This grafting process fundamentally alters the surface chemistry of the material, transitioning it from hydrophilic (water-attracting) to more hydrophobic (water-repelling) and improving its compatibility with organic matrices, such as polymers, resins, and solvents.

The modification of nanosilica with 3-Phenylpropyldimethylchlorosilane offers substantial advantages in numerous fields. Nanosilica, with its high surface area and unique size-dependent properties, is a widely used filler and additive. However, due to its inherent surface polarity and tendency to agglomerate, dispersing nanosilica uniformly within organic systems can be challenging. Surface modification with silanes addresses this issue directly. By attaching the non-polar phenylpropyl groups to the nanosilica surface, the nanoparticles become significantly more compatible with organic polymers and liquids, leading to improved dispersion, reduced aggregation, and enhanced performance when incorporated into composites, coatings, adhesives, and sealants.

The benefits derived from using 3-Phenylpropyldimethylchlorosilane modified nanosilica are diverse. In polymer composites, it can lead to improved mechanical strength, toughness, and thermal stability. In coatings and inks, it can enhance scratch resistance, weatherability, and rheological properties. Its application extends to the electronics industry, where modified silica can be used in encapsulants and thermal interface materials. Advanced materials sectors, including aerospace and automotive composites, also leverage the unique properties conferred by functionalized nanosilica.

Beyond nanosilica modification, 3-Phenylpropyldimethylchlorosilane finds utility in other areas where surface chemistry control is paramount. This can include serving as an intermediate in the synthesis of complex organosilicon compounds, or as a surface treatment for various substrates in different chemical processes. Its reactivity allows for versatile chemical transformations.
