摘要： Quaternary salts having a double helix structure are prepared by the reaction of dihydroxyaromatic compound, preferably a bisphenol, with an alkali metal hydroxide and a quaternary salt, such as a tetraalkylammonium or hexaalkylguanidinium chloride. The quaternary salts and their alkaline hydrolysis products are useful as catalysts in various reactions, including imide formation from bisphenol salts and halo- or nitro-substituted phthalimides and redistribution and equilibration of polycarbonates.

摘要： A method for preparing a metal salt of a hydroxy-substituted aromatic compound is described. The method comprises contacting in an aqueous medium at least one hydroxy-substituted aromatic compound with a base comprising a metal cation to provide a mixture comprising water and a metal salt of said hydroxy-substituted aromatic compound. The aqueous metal salt is then contacted with a substantially water-immiscible solvent at a temperature greater than the boiling point of water at the prevailing pressure to provide a slurry comprising the metal salt of the hydroxy-substituted aromatic compound and a vapor stream comprising the water-immiscible solvent and water. The components of the vapor stream are separated using a vapor handling system comprising a partial reflux condenser to provide a water-rich component and a water immiscible solvent-rich component.
