Assignee:

ATOFINA Chemicals, Inc. - Philadelphia PA

International Classification:

C08G 6302

US Classification:

528279, 528275, 528285, 5283081, 5283083, 502103, 502113, 502118, 502161, 502170

Abstract:

The present invention is based upon the discovery that nontitanyl oxalates can enhance the catalytic functionality of titanyl oxalate catalysts. This invention provides a novel catalytic composition containing a titanyl oxalate catalyst and a metallic oxalate catalyst enhancer and optionally containing a metallic cocatalyst such as an antimony based catalyst. A synergistic relationship has been discovered between titanyl oxalate catalyst and the catalyst enhancer. A synergistic relationship has also been discovered between the titanyl oxalate catalyst, catalyst enhancer and a metallic cocatalyst such as antimony oxide or antimony triacetate. Also provided is an improved process of producing polyester by the polycondensation of polyester forming reactants in the presence of a catalytically effective amount of a polycondensation catalyst, wherein the improvement comprises utilizing, as the polycondensation catalyst, the novel catalyst composition containing a titanyl oxalate such as lithium titanyl oxalate and a catalyst enhancer such as a nontitanyl metallic oxalate like lithium oxalate and optionally containing a metallic catalyst such as antimony oxide or antimony triacetate. The improved process produces an improved polyester having lower acetaldehyde numbers and good color. The titanyl oxalate/catalyst enhancer composition can be used as a polycondensation catalyst in combination with other catalysts to achieve synergistic catalytic activity.

International Classification:

C10L 1/18
C10L 1/22

US Classification:

44388, 44420, 44422, 44450

Abstract:

Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing a phenolic oxidant and a nonphenolic oxygen scavenger, which may be a hydroxylamine, an amine N-oxide, an oxime, or a nitrone. If an amine N-oxide is used, it may be used with or without a phenolic antioxidant. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase.

International Classification:

C10L 1/18

US Classification:

44397, 44398

Abstract:

The present invention relates to acrylic block polymers, either block copolymers or homopolymers, synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in bio-derived fuel compositions. They are especially useful in modifying the low temperature flow behavior in bio-derived fuels. The acrylic polymers are especially useful as cold filter plugging control additives in bio-derived fuels.

Abstract:

A catalyst composition for preparing polyesters comprises a titanium compound and one or more catalyst enhancers. The titanium compound may be either a titanyl compound of the formula XTiOYor a titanium salt of the formula XTiY, where each X is independently selected from the group consisting of H, Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba and ammonium; m=0, 1 or 2; Y is a ligand of the formula CHO, wherein a=1 to 30, b=0 to 60, and c=1 to 10; and o=2, 3, or 4. The catalyst enhancer may be selected from either or both of two classes: 1) compounds selected from the group consisting of oxalate and C1-C26 carboxylate salts of Li, Na, K, Rb, Cs, Be, Ca, Mg, Sr, and Ba; and 2) compounds selected from the group consisting of soluble compounds of Al, Co, Zn, and Sn.
