    摘要: A reaction slurry of a solid aromatic carboxylic acid such as terephthalic acid in mother liquor such as acetic acid which has been obtained by catalytic oxidation of an aromatic compound such as p-xylene in a solvent such as acetic acid is held in a washing zone to allow the solid acid to separate under gravity into fresh solvent, and a washed slurry of solid acid in solvent is withdrawn.
