Recovery of high purity 2,4-dinitrotoluene from spent mixed acid in toluene nitration process

Two easy practical methods for recovery of high purity 2,4-dinitrotoluene (DNT) from spent mixed acid in toluene nitration process are established. One is the dilution manner which produces high purity crystal of 2,4-DNT (>99 wt.%) by addition of proper amounts of deionized water into the spent m...
