  • Process for preparing substituted aromatic carboxylic acids
    Patent number: 8710260
    Abstract: A process for preparing an aromatic carboxylic acid having a heteroatom containing substituent is provided that includes reaction in a vessel of an aromatic precursor having an aromatic core with at least one heteroatom containing substituent and at least one hydrogen extending from the core, with a haloacetonitrile under reaction conditions to form an aromatic acetonitrile with an acetonitrile moiety. The aromatic acetonitrile is exposed to an oxidizing agent under conditions to convert the acetonitrile moiety to a carboxylic acid group to prepare the aromatic carboxylic acid having the heteroatom containing substituent.
    Type: Grant
