Reaction Steps
A catalyst is prepared using the general method of preparation described in Example 3, but without the addition of potassium nitrate and with a larger amount of molybdenum. The resulting catalyst corresponds to the formula W6Mo6.4 P1As0.2 Cu0.25 Ox. Under the test conditions of Example 3 and at a bath temperature of 306° C., the conversion is 67.2 mole %, and the selectivities with respect to methacrylic acid and acetic acid are 81.7 mole % and 5.1 mole % respectively. Maleic acid and citraconic acid are formed in a total amount of 1.8%.
