Abstract
"Process for the production of terephthalic acid" of fibrous grade from an impure terephthalic acid containing 4-carboxybenzaldehyde and other impurities, whose process is characterized in that it comprises the catalytic hydrogenation of said impure terephthalic acid in an aqueous solution at elevated temperature and pressure for a time sufficient to effect a substantial reduction of said 4-carboxybenzaldehyde, and the recovery of a fibre grade grade terephthalic acid, which contains substantially less than said 4-carboxybetazaldehyde and other impurities.
