CATALYST FOR THE MANUFACTURING OF ACRYLIC ACID AND A PROCESS FOR PRODUCING ACRYLIC ACID BY USING THE CATALYST

Document Type and Number:

WIPO Patent Application WO/2013/084500

Kind Code:

A3

Abstract:

This invention provides a catalyst for producing unsaturated carboxylic acid from unsaturated aldehyde which is obtained by dehydration reaction of alcohol. In particular, this invention provides a catalyst for producing acrylic acid from acrolein obtained by dehydration reaction of glycerin. This invention provides also a process for producing unsaturated carboxylic acid, especially acrylic acid by using the catalyst. Catalyst used contains an active ingredient having a composition represented by following formula (1): Mo12 Va Wb Cuc Sbd Xe Yf Zg Oh (1), in which Mo, V, W, Cu, Sb and O represent respectively molybdenum, vanadium, tungsten, copper, antimony and oxygen, X is at least one element selected from a group comprising alkali metals and thallium, Y is at least one element selected from a group comprising magnesium, calcium, strontium, barium and zinc, Z is at least one element selected from a group comprising niobium, cerium, tin, chromium, manganese, iron, cobalt, samarium, germanium, titanium and arsenic, "a", "b", "c", "d", "e", "f", "g" and "h" each represents an atom ratio of element and satisfies following respective range when a value for molybdenum atom is considered as 12: "a" is greater than 0 but not greater than 10, "b" is not less than 0 but not greater than 10, "c" is greater than 0 but not greater than 6, "d" is greater than 0 but not greater than 10, "e" is not less than 0 but not greater than 0.5, "f" is not less than 0 but not greater than 1, "g" is not less than 0 but less than 6 and "h" is a number of oxygen atom required for satisfying the valences of above elements.
