Petroleum ether is widely used as a non-polar solvent in laboratories for extracting oils, fats, and greases from various substances. It is also employed in the purification and separation of organic compounds due to its low boiling point and volatility. In industrial settings, it serves as a cleaning agent for removing residues and contaminants from machinery and equipment. Additionally, it is utilized in the production of adhesives, coatings, and varnishes, where it acts as a thinning agent to achieve the desired consistency. Its effectiveness in dissolving certain types of polymers makes it suitable for use in the formulation of rubber and plastics. In some cases, it is also used as a fuel additive to enhance combustion efficiency.
