ABSTRACT:
A process for the manufacture of aromatic dicarboxylic acids is disclosed using a low bromine to metals ratio facilitated by the use of cerium along with the cobalt and manganese catalyst. Aromatic dicarboxylic acids such as terephthalic acid are useful in the manufacture of fiber, films, bottles and molded products.
