Product Features

n-Decane is manufactured using advanced fractionation and purification technologies, ensuring consistent quality and precise boiling characteristics. The product features excellent solvency for non-polar compounds with a boiling point of 174°C, providing minimal evaporation loss during high-temperature processing. Its higher molecular weight (142.28 g/mol) offers enhanced solvency for certain high molecular weight polymers and specialty chemicals. The extremely low vapor pressure (1.3 mmHg at 25°C) significantly reduces worker exposure risk and evaporative emissions. The narrow boiling range and high purity ensure consistent performance in critical synthesis and analytical applications.

FAQ

What are the main advantages of n-Decane compared to lighter alkanes like n-Octane or n-Hexane?

n-Decane offers a significantly higher boiling point (174°C vs. 126°C for n-Octane) and much lower vapor pressure (1.3 mmHg vs. 10 mmHg for n-Octane), providing exceptional stability at elevated temperatures with minimal evaporative loss. Its higher solvency power for high molecular weight compounds and reduced flammability risk make it ideal for high-temperature industrial processes and extended reaction times. The reduced volatility also dramatically lowers worker exposure concerns and solvent losses during processing.

What purity grades are available for n-Decane and their typical applications?

The 98% grade is suitable for most industrial applications including high-temperature solvent formulations and general synthesis. The 99% grade provides higher purity for sensitive applications such as pharmaceutical intermediate synthesis, analytical reference standards, and specialty chemical production where precise composition and minimal impurities are critical. Research-grade material (99.5%+) is available for advanced applications requiring exceptional purity, including spectroscopic studies and high-precision physical property measurements.

What are the environmental and safety advantages of using n-Decane versus traditional solvents?

n-Decane's very low vapor pressure (1.3 mmHg at 25°C) significantly reduces volatile organic compound (VOC) emissions compared to lighter solvents like toluene or hexane. This translates to lower environmental impact, reduced worker exposure risk, and less solvent loss during processing. Its higher flash point (46°C) also reduces fire hazard compared to more volatile alternatives, allowing safer handling in industrial environments without specialized explosion-proof equipment in many applications.
