Application

Tetraethylene glycol, 99%, is a versatile high-boiling liquid designed primarily for use as a coupling agent and solvent capable of blending water-soluble and water-insoluble compounds in various applications. Its hygroscopic nature and complete miscibility with water and many organic solvents make it effective in formulating lubricants, glues, and textile products. Additionally, it serves as a solvent for water-insoluble compounds and is instrumental in roles such as a nitrocellulose solvent, plasticizer, natural gas desiccant, and in coatings and lacquers. Its applications extend to acting as a chemical intermediate and as a solvent in the production of inks, dyes, and textile formulations. Its molecular structure, comprised of ethylene glycol monomer units with two terminal hydroxyl groups, enhances its solubility and reactivity, offering further utility in the synthesis of derivatives like tetraethylene glycol methacrylate monomer.
