FormPowder
Terephthalic acid is used in the metal organic frame works. Terephthalic acid is used primarily to make polyethylene terephthalate (PET) resins and fibers, polyester fibers, films, polyethylene terephthalate solid-state resins and polyethylene terephthalate engineering resins.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
Terephthalic acid is used in the metal organic frame works. Terephthalic acid is used primarily to make polyethylene terephthalate (PET) resins and fibers, polyester fibers, films, polyethylene terephthalate solid-state resins and polyethylene terephthalate engineering resins.
Solubility
slightly soluble in water (0,017 g/L at 25°C)
Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. It should be stored and used in molten form.
