Description: n-Hexane is a straight-chain aliphatic hydrocarbon, mainly produced from crude oil distillation and cracking processes. It is a highly volatile, non-polar solvent with low density and poor water solubility. It is widely used for oil extraction, industrial cleaning, adhesive and paint thinning, and as a laboratory solvent. It is highly flammable; vapor may form explosive mixtures with air. Prolonged exposure may cause nerve system damage; aspiration may lead to chemical pneumonia.
