Claims
- 1. A composition of matter comprising a catalytic mixture resulting from contacting:
- at least one pyridine compound having the formula ##STR2## wherein each R is independently selected from the group consisting of hydrogen and --COOH, provided that at least one R group is a --COOH group;
- at least one organo-nickel compound wherein the nickel is in the zero valence state before formation of the active nickel component; and
- at least one clay compound wherein the weight ratio of said clay compound to said nickel is from about 1 to about 400.
- 2. A catalytic mixture according to claim 1 wherein said pyridine compound is selected from the group consisting of pyridine-2-carboxylic acid, pyridine-3-carboxylic acid, pyridine-1,5-dicarboxylic acid, pyridine-2,4,6-tricarboxylic acid, and mixture of two or more said pyridine compounds.
- 3. A catalytic mixture according to claim 1 wherein said pyridine compound is pyridine-2-carboxylic acid.
- 4. A catalytic mixture according to claim 1 wherein the molar ratio of said pyridine compound to nickel is from about 0.01 to about 2.
- 5. A catalytic mixture according to claim 1 wherein said clay compound is selected from the group consisting of aluminum silicate clays, magnesium silicate clays, aluminum-magnesium silicate clays, and mixtures of two or more of said clay compounds.
- 6. A catalytic mixture according to claim 1 wherein said clay compound is selected from the group consisting of attapulgite, bentonite, halloysite, hectorite, kaolinite, montmorillonite, pyrophylite, sepiolite, talc, vermiculite, and mixtures of two or more said clay compounds.

- 9. A catalytic mixture according to claim 1 wherein said clay compound is sepiolite.
- 10. A catalytic mixture according to claim 1 wherein said clay compound is bentonite.
- 11. A catalytic mixture according to claim 1 wherein the weight ratio of clay compound to nickel is from about 10 to about 300.
- 12. A catalytic mixture according to claim 1 wherein said nickel compound is bis(1,5-cyclooctadiene) nickel.
- 13. A composition of matter comprising a catalytic mixture resulting from contacting:
- (a) pyridine-2-carboxylic acid;
- (b) bis(1,5-cyclooctadiene) nickel; and
- (c) a clay compound selected from the group consisting of sepiolite, bentonite, and mixtures thereof; wherein the weight ratio of clay compound to nickel is from about 1 to about 500.
- 14. A catalytic mixture according to claim 13 wherein the molar ratio of said pyridine-2-carboxylic acid to nickel is from about 0.01 to about 2.
