Abstract
Dinitrostilbene 2,2' disulfonic acid was synthesized through air oxidation of 4 nitrotoluene 2 sulfonic acid using MnSO\-4 as catalyst.The termination of reaction was determined by UV tracing.The yield was increased by 10%-15%,the amount of wastewater reduced by 50% and the reaction time shortened by 10h in this procedure compared with the conventional procedure using FeSO\-4 as catalyst.
