    摘要： A method of preparing hindered phenolic antioxidants for lubrication oils or other organic media having reduced residual tin or titanium levels is disclosed herein. A low amount of a tin or titanium catalyst is used resulting in low residual metal levels. The method provides for deactivation of the metal transesterification catalyst with an oxidizing agent, a reducing agent or clay treatment. Treatment with clay, preferably acid treated clay, and more preferably acid treated bentonite clay, after deactivation with the oxidizing agent or reducing agent can further reduce residual tin levels to less than 10 ppm. By deactivating the metal catalyst prior to isolating the antioxidant from the reaction mixture, further reaction at the terminal diol of the reaction product is prevented. The final product mixture may be used without further purification and has improved solubility in lubrication oils and other organic media.

    摘要： The present invention relates to agricultural articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of agricultural articles. The desired effect is obtained with specific combinations of degradant metal salts and stabilizers.
    The agricultural article of the present invention comprises an organic polymer, an organic salt of Fe, Ce, Co, Mn, Cu or Vd and one or more sterically hindered amine compounds.
