Claim:
A process of manufacturing synthesis MAL comprises the steps of: (a) preheating one member selected from the group consisting of isobutene and t-butanol with oxygen containing gas and steam to form a reactant; and (b) introducing said reactant into a reactor which is loaded with a catalyst composition to incorporate with said reactant to form a synthesis MAL, said catalyst composition being represented by the formula of: x(Mo 12 Bi a Fe b Co c A d B e O f )/yZ wherein Mo 12 Bi a Fe b Co c A d B e O f is an oxide compound, wherein Z is a catalyst carrier selected from the group consisting of graphite, boron, silicon, germanium powder, and mixtures thereof, wherein Mo, Bi, Fe, Co, and O are chemical symbols of molybdenum, bismuth, iron, cobalt, and oxygen respectively, wherein A is at least one member selected from the group consisting of W, V, Ti, Zr, Nb, Ni, and Re, wherein B is at least one member selected from the group consisting of K, Rb, Cs, Sr, and Ba, wherein a, b, c, d, and e are the atomic ratios of Mo, Bi, Fe, Co, A, and B respectively, wherein f is determined by the atomic ratios of each component of said oxide compound, wherein x and y represent the quantity of said oxide compound and the quantity of said carrier Z respectively, wherein a, b, c, d, e and f satisfy the requirement of a=0.1 to 15, b=0.05 to 10, c=1 to 15, d=0.01 to 5, e=0.01 to 2; wherein said x and said y has a relationship determined by a formula of y/(x+y).
