FAQ

What are the physical and chemical properties of Pentadecane (CAS: 629-62-9)?

Pentadecane (CAS: 629-62-9) is a colorless, odorless liquid with a molecular weight of approximately 222.34 g/mol. Its density is around 0.798 g/cm³. Pentadecane has low solubility in water but is soluble in many organic solvents. It is relatively non-reactive under normal conditions but can undergo thermal decomposition at high temperatures. It is insoluble in acids and bases.

How is Pentadecane (CAS: 629-62-9) typically synthesized?

Pentadecane (CAS: 629-62-9) can be synthesized through the catalytic hydrogenation of pentadecyne or by hydrodeoxygenation of tetradecanol. Common catalysts include palladium on carbon. The synthesis yields high purity products with good selectivity and high yields, typically around 90-95%. The process is usually carried out under mild conditions to preserve the integrity of the pentadecane molecule.

What industries use Pentadecane (CAS: 629-62-9)?

Pentadecane (CAS: 629-62-9) is used in a variety of industries. It is a key component in the production of pharmaceuticals, particularly as a solvent for drugs that are poorly soluble in water. It is also used in the polymer industry as a plasticizer or in the synthesis of other compounds. Additionally, pentadecane is utilized in the development of sensors due to its thermal stability and its ability to detect specific chemical or physical changes. It is also used in the semiconductor industry as a cleaning agent or in the fabrication of electronic devices.

What precautions should be taken when handling Pentadecane (CAS: 629-62-9)?

When handling Pentadecane (CAS: 629-62-9), it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and protective clothing. It should be stored in a cool, dry place away from sources of ignition and incompatible materials. Spills should be handled using appropriate spill kits, and the area should be well-ventilated. In the event of skin or eye contact, immediate flushing with water is recommended. For more detailed information, refer to the Safety Data Sheet (SDS) for Pentadecane (CAS: 629-62-9).
