Abstract

In accordance with the invention, there is provided a novel catalyst composition comprising MoVGaPdNbXY, wherein X comprises La, Te, Ge, Zn, In, or W; and Y comprises Al or Si; wherein Mo, V, Ga, Pd, Nb, La, Te, Ge, Zn, In, W, Al, or Si are optionally present in combination with oxygen; wherein the catalyst does not comprise an additional element that acts as a catalyst in the conversion of a propylene to the product. Also, disclosed is a method for the conversion of a propylene to a carboxylic acid moiety by contacting the propylene with the disclosed catalyst.

First claim

What is claimed is:

1. A catalyst for the conversion of propylene to a product comprising a carboxylic acid moiety, wherein the catalyst comprises:
MoVGaPdNbXY,
wherein
X is La, Te, Ge, Zn, In, or W; and
Y is Al or Si;

wherein
one or more of Mo, V, Ga, Pd, Nb, La, Te, Ge, Zn, In, W, Al, and/or Si are optionally present in combination with oxygen;

wherein the product does not comprise substantially any acrolein.

2. The catalyst of claim 1 , wherein the product does not comprise any acrolein.

3. A catalyst for the conversion of propylene to a product comprising a carboxylic acid moiety, wherein the catalyst consists essentially of:
MoVGaPdNbXY,
wherein
X is La, Te, Ge, Zn, In, or W; and
Y is Al or Si;

wherein
Mo, V, Ga, Pd, Nb, La, Te, Ge, Zn, In, W, Al, and/or Si are optionally present in combination with oxygen; and

wherein the product does not comprise substantially any acrolein.

4. The catalyst of claim 3 , wherein the catalyst is present on a support.

5. The catalyst of claim 3 , wherein the catalyst comprises:
Mo a V b Ga c Pd d Nb e X f Y g
wherein a is 1; b is present in an amount that ranges from 0.01 to 0.90; c is present in an amount that ranges from greater than 0 to 0.20; d is present in an amount that ranges from 0.0000001 to 0.20; e is present in an amount that ranges from greater than 0 to 0.20; f is present in an amount that ranges from greater than 0 to 0.80; and g is present in an amount that ranges from greater than 0.50 to 0.90;
wherein the numerical values of a, b, c, d, e, f, and g represent the relative gram-atom ratios of the elements in the catalyst.

6. The catalyst of claim 3 , wherein the product comprises acetic acid, acrylic acid, or propanoic acid, or a combination thereof.

7. The catalyst composition of claim 3 , wherein the catalyst converts the propylene to the product comprising the carboxylic acid moiety in a single stage.

8. A method for the conversion of propylene to a product comprising a carboxylic acid moiety, wherein the method comprises:
contacting the propylene with a catalyst, wherein the catalyst comprises:
MoVGaPdNbXY,

 wherein
X is La, Te, Ge, Zn, In, or W; and
Y is Al or Si;

 wherein
Mo, V, Ga, Pd, Nb, La, Te, Ge, Zn, In, W, Al, and/or Si are optionally present in combination with oxygen; and

wherein the product does not comprise substantially any acrolein.

9. The method of claim 8 , wherein the product comprises acetic acid, acrylic acid, or propanoic acid, or a combination thereof.

10. The method of claim 8 , wherein the method does not comprise an additional catalyst.

11. The method of claim 8 , wherein the method comprises a single stage process with a single catalyst.

12. The catalyst of claim 1 , wherein the catalyst is present on a support.

13. The catalyst of claim 1 , wherein the catalyst comprises:
Mo a V b Ga c Pd d Nb e X f Y g
wherein a is 1; b is present in an amount that ranges from 0.01 to 0.90; c is present in an amount that ranges from greater than 0 to 0.20; d is present in an amount that ranges from 0.0000001 to 0.20; e is present in an amount that ranges from greater than 0 to 0.20; f is present in an amount that ranges from greater than 0 to 0.80; and g is present in an amount that ranges from greater than 0.50 to 0.90;
wherein the numerical values of a, b, c, d, e, f, and g represent the relative gram-atom ratios of the elements in the catalyst.

14. The catalyst of claim 1 , wherein the product comprises acetic acid, acrylic acid, or propanoic acid, or a combination thereof.

15. The catalyst of claim 1 , wherein the catalyst converts the propylene to the product comprising the carboxylic acid moiety in a single stage.

16. The catalyst of claim 1 , wherein less than 1% of acrolein is formed in the product using the catalyst.

17. The catalyst of claim 3 , wherein less than 1% of acrolein is formed in the product using the catalyst.

18. The method of claim 8 , wherein less than 1% of acrolein is formed in the product using the catalyst.
