Aromatic compounds are nitrated in the vapor phase via a process comprising contacting the aromatic compounds with a nitrating agent in the presence of a nitration promoting catalyst composition represented by the empirical formula: (M1aM2bOc)x(NO2)y wherein M1 is at least one element selected from Group 4b of the Periodic Table of the Elements, M2 is at least one element selected from Group 3b of the Periodic Table of the Elements, a is 1, b is 0 to 20, c is a number taken to satisfy the average valences of M1 and M2 in the oxidation states in which they exist in the composition, x is 1, and y is 0 to c. |
