  • Applications

    Tetralin (CAS 119-64-2) is principally used as a non-polar organic solvent for resin and coating systems, supporting dissolution of resins, oils and waxes in coatings, inks, and adhesive formulations. It also serves as a processing solvent in the polymer and plastics industry, aiding dissolution and formulation prior to molding or extrusion. In energy and refining contexts, tetralin is used as a hydrogen-donor solvent to facilitate coal liquefaction and hydroprocessing reactions. It functions as an intermediate in chemical synthesis, enabling the preparation of hydrogenated aromatic derivatives and other bicyclic compounds. Additionally, it may be employed as a cleaning solvent for industrial metal parts and processing equipment where a non-halogenated hydrocarbon solvent is appropriate.
