Description and Uses
Tetraethylene glycol is a polymer consisting of ethylene glycol monomer units and two terminal hydroxyl groups. The hydroxyl groups can react to further derivatize the compound. Ethylene glycol compounds have hydrophilic characteristics. The solubility of the polymer increases as the number of ethylene glycol groups increase.
Tetraethylene glycol is used as a solvent to dissolve water-insoluble compounds. It is employed as a nitrocellulose solvent, a plasticizer, a natural gas desiccant, a hydraulic fluid and in lacquers and coatings. Furthermore, it is used in the synthesis of tetraethylene glycol methacrylate monomer. It acts as a chemical intermediate and acts as a solvent for the manufacturing of inks and dyes. In addition, it serves as a coupling agent in the production of textile lubricants and formulations.
