CAS 139-02-6: Phenol, sodium salt

Sodium phenoxide

Sodium phenoxide is used as a precursor to aryl ethers and involved in the preparation of phenyl ethers and metal phenolates. It serves as an antiseptic and used in organic synthesis. 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.

Sodium phenoxide is a glycol ether that has been used to treat wastewater containing phenol and p-hydroxybenzoic acid. The reaction solution is prepared by mixing the desired amount of sodium phenoxide with an excess of copper chloride in anhydrous sodium. This process can be monitored using electrochemical impedance spectroscopy, which provides information about the chemical stability of the product. The use of sodium phenoxide as a wastewater treatment agent can be evaluated through treatment trials, where it is mixed with wastewater containing different concentrations of inhibitor drugs such as metoprolol succinate. Langmuir adsorption isotherm can also be used to determine the effectiveness of this product for wastewater treatment purposes.
