Cyclohexyltrimethoxysilane (CHTMS) is a specialized organosilane compound with a unique set of properties that make it invaluable in various industrial applications, particularly in the realm of polymer production. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the importance of understanding these characteristics to fully leverage the potential of this versatile chemical. This article will explore the key physical and chemical attributes of CHTMS and its primary applications, shedding light on why it is a preferred choice for many manufacturers.

As a colorless, transparent liquid, Cyclohexyltrimethoxysilane presents an approachable profile for handling and integration into existing chemical processes. Its molecular formula, C9H20O3Si, and molecular weight of 204.33900, indicate a compound that is both manageable and potent in its chemical interactions. The physical properties are notable: a boiling point of approximately 207°C signifies its stability at elevated temperatures, while a melting point below 0°C ensures it remains liquid under typical storage conditions. Its refractive index of 1.433 further attests to its optical clarity.

The purity of CHTMS is a critical factor for its effectiveness, and specifications often exceed 99.00% Cyclohexyltrimethoxysilane content by weight. This high purity, coupled with a low color scale (≤20 Hazen units), guarantees consistency and reliability in demanding applications. These attributes are essential for manufacturers who need to buy cyclohexyltrimethoxysilane for processes where precision is key, such as advanced catalysis.

The principal application of Cyclohexyltrimethoxysilane lies in its role as an additive for propylene polymerization. Here, it acts as an efficient and non-toxic external electron donor. This function is fundamental to improving catalyst activity, enhancing stereospecificity in polypropylene production, and significantly extending the operational life of catalysts. The ability to fine-tune the stereochemistry of polymers is crucial for achieving desired material characteristics, making CHTMS a vital component in the synthesis of high-performance polyolefins.

Proper handling and storage are also key considerations for CHTMS. It is typically supplied in sealed drums under nitrogen protection to prevent oxidation and moisture ingress, which could lead to degradation. Storage in a cool, dry, and well-ventilated environment, away from incompatible substances like acids, alkalis, and oxidants, is recommended to maintain its stability and efficacy for up to 12 months.
