Application

1‌). Industrial Uses‌: Primarily employed as a non-polar solvent in specialty coatings, polymer research, and rubber formulations.
2‌). Phase Change Material (PCM)‌: Utilized in thermal energy storage systems due to its stable solid-liquid transition near 28-30°C.
3‌). Organic Synthesis‌: Serves as a reference hydrocarbon in chromatography and as a reaction medium for lipid studies.
4‌). Consumer Products‌: Functions as a viscosity modifier in limited cosmetic applications (e.g., hair care formulations).

 

 

Storage

 

1). Maintain in tightly sealed containers under inert gas (N₂/Ar) to prevent oxidation.
2). Store at ambient temperature (15-25°C) in well-ventilated areas separate from strong oxidizers.
3). Ground containers to mitigate static discharge risks.

 

 

Stability

 

1). Chemical Stability‌: Generally inert under standard conditions; reacts with halogens and concentrated acids.
2). Thermal Limits‌: Stable to 200°C; above 250°C undergoes pyrolysis yielding lower alkanes/alkenes.
3). Light Sensitivity‌: Prolonged UV exposure may induce minor decomposition; amber glass recommended for long-term storage.
4). Material Compatibility‌: Compatible with PTFE, HDPE, and stainless steel; avoid contact with copper alloys.
