Abstract:
The present invention relates to a method for preparing a catalyst and a method for preparing unsaturated carboxylic acid using the catalyst prepared according to the preparation method. According to the method for preparing a catalyst, unsaturated carboxylic acid can be provided from an unsaturated aldehyde with a high conversion rate and selectivity.

Claim (Index 1):
A method for preparing a catalyst represented by the following Chemical Formula 1, comprising the steps of:\n mixing and stirring a metal precursor to prepare a slurry; drying the slurry at 110\u00b0 C. to 130\u00b0 C., and grinding, kneading, and conducting first compression molding; drying the first compression molded material at 110\u00b0 C. to 130\u00b0 C., and grinding and conducting second compression molding; and firing the second compression molded material at 300\u00b0 C. to 500\u00b0 C., wherein a ligand sublimation rate calculated by the following Mathematical Formula 1 is 0 wt % or more:\n ligand sublimation rate (wt %)=amount of sublimed ligand (kg)/amount of ligand before sublimation (kg)*100;\u2003\u2003[Mathematical Formula 1] \n Mo 12 P a A b B c C d D e E f O g \u2003\u2003[Chemical Formula 1] \n wherein, in Chemical Formula 1, A is one or more elements selected from the group consisting of W, V, Nb, and Cr; B is one or more elements selected from the group consisting of As, B, Sb, Ce, Pd, and Te; C is one or more elements selected from the group consisting of Si, Al, Zr, Rh, Cu, Ti, Ag, and Sn; D is one or more elements selected from the group consisting of Na, K, Li, Rb, Cs, Ta, Ca, Mg, Sr, and Ba; and E is one or more elements selected from the group consisting of Fe, Co, and Ni, and a, b, c, d, e, f, and g represent the atomic ratio of each element, where a is 0.5 to 2, b is 0.01 to 10, c is 0 to 15, d is 0.01 to 20, e is 0.01 to 20, f is 0.01 to 15, and g is a value determined by the oxidation state of each atom.
