Cyclohexyldimethoxymethylsilane (CMDMS) is a fascinating organosilicon compound that plays a vital role in advanced chemical manufacturing, particularly as a catalyst additive. For procurement specialists and R&D scientists looking to buy this specialized chemical, understanding its fundamental properties, synthesis, and purity requirements is essential. As a dedicated manufacturer of high-quality chemical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the critical nature of these aspects for optimal performance in applications like propylene polymerization.

With the chemical formula C9H20O2Si and CAS number 17865-32-6, Cyclohexyldimethoxymethylsilane is characterized by its appearance as a colorless, transparent liquid. Its molecular weight is approximately 188.34 g/mol. Key physical properties crucial for its application include a boiling point typically around 201.2 °C, a flash point of approximately 66 °C, and a refractive index of about 1.439 (n20/D). These parameters are indicative of its stable nature under controlled conditions, yet it's important to note its compatibility and reactivity with moisture and water, which can lead to hydrolysis.

The synthesis of Cyclohexyldimethoxymethylsilane can be achieved through several chemical routes. Common methods include direct alkylation of dimethoxysilane with chloromethylcyclohexane or hydrosilylation of vinylcyclohexane in the presence of a suitable catalyst. The choice of synthesis method significantly impacts the final product's purity. Achieving a high assay, often ≥99.5%, is paramount. Impurities can interfere with catalytic activity, reduce stereospecificity, and negatively affect the final polymer's characteristics. Therefore, sourcing from a reliable supplier in China that prioritizes stringent quality control during synthesis is vital.

The application of Cyclohexyldimethoxymethylsilane extends beyond being a mere chemical intermediate; it serves as a potent polymerization control agent. In Ziegler-Natta catalysis, its function as an external electron donor is well-documented. It precisely modulates the active sites of the catalyst, enhancing the selectivity towards the desired polymer structure, such as isotactic polypropylene. This control is directly linked to the compound's chemical structure and purity.

For businesses looking to integrate this compound into their manufacturing processes, understanding its handling and storage is also important. It is typically stored in tightly sealed containers in dry, well-ventilated areas, away from heat and ignition sources. Its status as a combustible liquid necessitates adherence to safety protocols. When you inquire about the price or need to purchase Cyclohexyldimethoxymethylsilane in bulk, consider the expertise and reliability that NINGBO INNO PHARMCHEM CO.,LTD. offers as a specialized organosilicon chemical manufacturer.
