Document Type and Number:
Japanese Patent JPH0525550
Kind Code:
B2
Abstract:
Catalysts compositions useful to catalyze the nitration of aromatic compounds in the vapor phase to produce nitroaromatic compounds are 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 0.050 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. The compositions are particularly effective to catalyze the vapor phase nitration of chlorobenzene and are characterized in such reaction by providing a para/ortho isomer distribution ratio of at least about 1.9/l.
