  • Manufacture of aromatic amines
    Patent number: 5886189
    Abstract: Sulfur-contaminated aromatic nitro compounds are hydrogenated in the presence of a chrominum-containing Raney cobalt catalyst to corresponding primary amino compounds which are useful as intermediates for photographic dye-forming couplers and for other purposes.
    Type: Grant
    Filed: November 25, 1992
    Date of Patent: March 23, 1999
    Assignee: Eastman Kodak Company
    Inventor: Victor LaVonne Mylroie
  • Method of synthesizing tert-amido-substituted 2-(2'-hydroxyphenyl) benzotriazole compounds in a one-step process
    Patent number: 5739348
    Abstract: A method for preparing a compound of formula (III): ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, L, Z and p are as defined in the specification;said process preferably comprising either a noble metal catalyzed hydrogenation or a non-catalytic reductive ring closure of an azo dye compound of formula (IV): ##STR2## where R11 is as defined in the specification, thereby performing a reductive ring closure and selective O-deacylation in a single process step.
    Type: Grant
