    • 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.
    • 描述了制备羟基取代的芳族化合物的金属盐的方法。 该方法包括在含水介质中使至少一种羟基取代的芳族化合物与包含金属阳离子的碱接触以提供包含水和所述羟基取代的芳族化合物的金属盐的混合物。 然后在主要压力下,在大于沸点的温度下,将水性金属盐与基本上与水不混溶的溶剂接触,以提供包含羟基取代的芳族化合物的金属盐和包含水的蒸汽流的浆料 可混溶的溶剂和水。 使用包含部分回流冷凝器的蒸汽处理系统分离蒸气流的组分以提供富含水的组分和与水不混溶的富含溶剂的组分。
