Latest Patents
Jos H Graff holds a patent for a process titled "Phenol recovery from BPA process waste streams." This patent discloses a method for recovering valuable phenol and acetone from by-products generated during the condensation of phenol and a ketone. The process utilizes a mother liquor obtained from the crystallization of a 1:1 adduct of phenol and bisphenol. The mother liquor contains various components, including phenol, bisphenol, isomers, and contaminant by-products. The innovative recovery process involves distilling or evaporating the mother liquor, leaving behind a tarry residue that serves as the feedstock. This feedstock is then catalytically cracked with aromatic sulfonic acid to extract bisphenol-A values as phenol and acetone.
