Reaction Steps
A catalyst of the general formula W6Mo4W0.3 P1As0.3 Sb0.25 Cu0.3 Cs0.8 Ox is prepared by the procedure described in Example 1, and is tested under the conditions stated in Example 2. At a bath temperature of 324° C., the conversion is 54.5 mole %, and the selectivities with respect to the methacrylic acid and acetic acid are 85.5 mole % and 2.7 mole % respectively. Maleic acid and citraconic acid are formed in a total amount of 0.85%, based on the methacrylic acid.
