  • Publication number: 20240376034
    Abstract: The present disclosure provides a method for isolating dialkylene phenolic glycol ether (DPGE) from a mixture that includes DPGE and glycosylated phenol impurities. The method includes adding a source of an alkali metal to the mixture to form a phenolic glycol product having an alkali phenolic salt formed from a reaction between the alkali metal and the glycosylated phenol impurities; and separating the DPGE from the alkali phenolic salt in the phenolic glycol product through a thin film evaporation process to produce a dialkylene phenolic glycol ether product. The disclosure also includes a phenolic glycol product that includes DPGE; water; glycosylated phenol impurities; a source of alkali metal; and an alkali phenolic salt formed from a reaction between the alkali metal and the glycosylated phenol impurities.
