Investigations of the reactions of monochloramine and dichloramine with selected phenols: Examination of humic acid models and water contaminants
The phenols are an important area of investigation because they are substituents in the humic acids and are common contaminants in water. The reactivities and orientations of two common phenols (phenol and m-cresol), and some of their chlorinated intermediates with aqueous monochloroamine and dichloroamine were presented. m-Cresol was more reactive than phenol with both chlorinating agents. NH2Cl and NHCl2 showed extensive reactivity toward the phenols, even the partially chlorinated less reactive intermediates would be expected to fully chlorinate the activated positions in phenolic substituents in the humic acids.

Reactive dyestuffs
Triphendioxazine reactive dyestuffs of the general formula STR1 with the substituent definition given in the description, are outstandingly suitable for dyeing and printing materials containing hydroxyl groups or amide groups. They give red dyeings with high wet- and light-fastnesses.
