Natural zeolite and sulfated natural zeolite catalyst materials have been successfully prepared, characterized, and applied
as a replacement for the role of a sulfuric acid catalyst in the synthesis of nitrobenzene. Natural zeolites were prepared
into uniform-sized powders and then refuxed with H2SO4 with varying concentrations of 0, 1, 2, 3, and 4 M, proceeded
by calcination with N2 gas fow (labeled as NZ, SNZ-1, SNZ-2, SNZ-3, and SNZ-4). Nitrobenzene was synthesized in a
batch microwave reactor using natural zeolite and sulfated natural zeolite catalysts with the best acidity value. The results
showed that the sulfuric acid treatment of natural zeolite caused changes in its physical and chemical characteristics. The NZ
catalyst has an acidity value of 1.742 mmol g−1, and the 2 M concentration variation resulted in the sulfated natural zeolite
with the best acidity value of 1.625 mmol g−1. The optimal amount of catalyst required is 1.0 g. Both catalysts are selective
toward the nitration reaction of benzene. The average benzene conversion produced for each catalyst was 41.53±3.61% and
58.92±1.37%. Furthermore, the SNZ-2 catalyst has better reusability for three reaction runs.
