  • Highly over-based light colored liquid alkaline earth metal carboxylate
    Publication number: 20060194704
    Abstract: An overbased alkaline earth metal organic complex of a carboxylic acid is formed by the reaction of a basic alkaline earth metal compound, and alcohol and/or glycol, a carboxylic acid, and carbon dioxide, wherein the carboxylic acid is a non-fatty alkyl group-containing carboxylic acid, such as one containing an alkyl group of up to eight carbon atoms and/or one containing an alkyl-substituted or unsubstituted aromatic group.

  • Process for improving shelf stability of liquid overbased calcium carboxylates, mixed metal stabilizers containing same, and stabilizing halogen-containing polymers therewith
    Patent number: 6348164
    Abstract: Shelf stable liquid overbased calcium carboxylates are prepared by reacting a calcium base with a monocarboxylic acid, and carbonating in the presence of a promoter mixture with a phenol and an alcohol under controlled temperature conditions, to produce shelf stable liquids. Mixed metal stabilizer compositions are prepared by blending the stable liquid calcium carboxylate with a metal carboxylate of zinc, cadmium or tin. The mixed metal carboxylates are also shelf stable and are used for stabilizing halogen-containing polymers to provide heat stability, clarity and improved plate out properties.

  • Process for improving color of basic metal organic salts and stabilizing halogen-containing polymers therewith
    Patent number: 5859267
    Abstract: A light colored basic alkali or alkaline earth metal organic salt is obtained by the reaction of a basic metal compound, an alkyl phenol and/or a carboxylic acid, carbon dioxide, and thereafter post-treating the reaction product with an organic phosphite. Alkaline earth metal salts of phenols and carboxylic acids include barium or calcium. Organic phosphites include trialkyl or dialkyl phosphites such as triisodecyl phosphite or diisooctyl phosphite.
