Patent ID: 7759525

Claim:
A process for manufacturing a partial oxidation product of a lower alcohol wherein a lower alcohol is subjected to vapor phase contact oxidation with a molecular oxygen containing gas in the presence of a catalyst, wherein the lower alcohol is an alkanol, and the partial oxidation product of the lower alcohol is a dialcoxyalkane, wherein a catalyst having the following composition (I): Mo 12 V a X 1 b , X 2 c X 3 d X 4 e O x (I) wherein : Mo is molybdenum; V is vanadium; O is oxygen; X 1 is at least one element selected from tungsten, titanium, tantalum and niobium; X 2 is at least one element selected from copper, antimony, tellurium and bismuth; X 3 is at least one element selected from alkaline earth metals; X 4 is at least one element selected from alkaline metals; and 0<a≦10; 0≦b≦4; 0<c≦5; 0≦d≦2; 0≦e≦2; and x is a numerical value determined by the extents of the oxidation of the other elements, is used.
