In the dynamic landscape of material science, specialized chemical compounds play a pivotal role in enabling innovation and improving product performance. Among these, organosilicon compounds, particularly siloxanes, have garnered significant attention due to their unique properties and versatility. This article delves into the significance of octyl-substituted siloxanes, focusing on 1,3-Di-n-octyltetramethyldisiloxane (CAS 18642-94-9), and its growing importance in various industrial applications. As a leading manufacturer and supplier, we are committed to providing high-quality materials that drive progress in the field.

1,3-Di-n-octyltetramethyldisiloxane is a disiloxane derivative characterized by the presence of two n-octyl groups attached to silicon atoms, alongside methyl groups. This specific molecular architecture imbues the compound with distinct hydrophobic and oleophilic characteristics, making it a valuable component in formulations where surface properties are critical. Its structure, C20H46OSi2, with a molecular weight of approximately 358.76 g/mol, contributes to its unique performance profile. The compound typically appears as a clear liquid, with a density of around 0.891 g/mL, and a boiling point in the range of 122-125 °C at a reduced pressure of 0.2 mmHg, indicating good thermal stability for many processes. Its flash point, exceeding 110 °C, also signifies a favorable safety profile for handling and industrial use.

The application of 1,3-Di-n-octyltetramethyldisiloxane spans several key sectors. In the realm of specialty chemicals, it serves as a crucial intermediate for synthesizing more complex silicone polymers and fluids. Its long alkyl chains can impart enhanced lubricity, water repellency, and flexibility to the final products. This makes it an attractive ingredient for formulators in industries such as cosmetics and personal care, where smooth texture and emolliency are desired. Furthermore, in industrial coatings and lubricants, its presence can improve surface wetting, reduce friction, and enhance the overall durability of the applied films or lubrication systems.
