  • 3-Halo-2,6-dinitro-4-trifluoromethylanilines
    Patent number: 4046758
    Abstract: 3-Halo-2,6-dinitro-4-trifluoromethylanilines having hydrocarbon substituents on the nitrogen atom. The hydrocarbon substituents can be alkyl, alkenyl, alkynyl or a portion of a heterocyclic group. The compounds are especially useful as intermediates for preparing herbicidal dinitro-1,3-phenylenediamines.
    Type: Grant

  • Method for descaling ferrous metals
    Patent number: 3951681
    Abstract: A ferrous metal product to be cleaned is immersed in an oxidizing molten salt bath forming a conditioned scale on the surface of the metal. The conditioned scale is subsequently removed from the metal surface by immersing the metal product in an aqueous caustic bath containing alkali metal hydroxide with alkali gluconate and triethanolamine serving as sequestering agents. The caustic bath may optionally include a brightening catalyst or ethylenediamine-tetracetic acid.
