Petroleum ether is widely used as a non-polar solvent in laboratories for extracting oils, fats, and greases from various substances. It is particularly useful in the preparation of samples for analysis, such as in chromatography and spectroscopy. In industrial settings, it serves as a cleaning agent for removing oil residues from machinery and metal parts. Additionally, it is employed in the production of varnishes, paints, and coatings due to its ability to dissolve a range of organic compounds. Its low boiling point makes it suitable for use in processes requiring quick evaporation, such as in the manufacturing of adhesives and inks. Petroleum ether is also utilized in the pharmaceutical industry for the extraction of active ingredients from plant materials.
