Description and Uses
n-octadecane is used as a solvent, a lubricant, transformer oil and an anti-corrosion agent. It is also used in paraffin and as a chemical intermediate in organic synthesis. It plays an important role in pheromones as a chemical messenger. N-Octadecane/ molecular sieve 5A composites find application as thermal storage material.
