Catalyst For Oxidation Of Saturated And Unsaturated Aldehydes To Unsaturated Carboxylic Acid, Method Of Making And Method Of Using Thereof

View page
US Patent:
7273829, Sep 25, 2007
Filed:
Dec 22, 2005
Appl. No.:
11/316211
Inventors:
Wugeng Liang - Katy TX, US
Scott A. Stevenson - Houston TX, US
Joseph R. Linzer - Houston TX, US
Assignee:
Saudi Basic Industries Corporation - Riyadh
International Classification:
B01J 23/00
US Classification:
502300, 502240, 502241, 502242, 502243, 502245, 502246, 502247, 502248, 502250, 502263, 502302
Abstract:
The invention is a supported or bound heteropoly acid catalyst composition, a method of making the catalyst composition and a process for the oxidation of saturated and/or unsaturated aldehydes to unsaturated carboxylic acids using the catalyst composition. The catalyst composition has an active heteropoly acid component containing molybdenum, vanadium, phosphorus and cesium and an inert heteropoly acid component containing molybdenum, phosphorus and cesium, potassium, rubidium or sodium at a relative molybdenum:cesium/potassium/rubidium/sodium molar ratio of above about 12:2. The catalyst is made by dissolving compounds of the components of each of the heteropoly acid compounds in a solution, precipitating the heteropoly acid compounds, contacting the heteropoly acid compounds to form a catalyst precursor and calcining the catalyst precursor to form a heteropoly acid compound catalyst. Unsaturated aldehydes, such as methacrolein, may be oxidized in the presence of the heteropoly acid compound catalyst to produce an unsaturated carboxylic acid, such as methacrylic acid.
