  • Patent number: 8076495
    Abstract: A process for the preparation of aromatic N-glycidylamines is described, wherein an amine which contains at least one aromatic aminehydrogen atom is heated with at least 0.7 equivalent of epichlorohydrin per aminehydrogen equivalent of the aromatic amine, using a divalent or polyvalent metal salt of nitric acid, as a catalyst, dissolved in propylene carbonate, and the product is then dehydrochiorinated.

  • Patent number: 4154722
    Abstract: Polyalkylpiperidinyl esters of diazocarboxylic acids are prepared, which compounds protect organic polymers against UV light degradation. The light stabilizers have the ability to react with the organic polymeric substrates thus making the piperidinyl esters migration and extraction resistant. Polymers which may be stabilized with the compounds of this invention include polypropylene, polyethylene, polystyrene and polyamides.
