TAMLTM Oxidant Activators: Green Bleaching Agents for Paper Manufacturing

Module Description

Author Contact:


Chlorine based processes for bleaching paper use redox chemistry that produces a complex mixture of chlorinated products that are hazardous to human health and the environment. This module describes the development and use of tetraamido-macrocyclic ligand activators (TAMLTM) as oxidant activators to reduce the environmental impact of the bleaching process. TAMLTM activators are iron macrocyclic structures that catalyze hydrogen peroxide oxidation reactions important for bleaching paper. The TAMLTM based technology is more efficient and can be used at lower temperatures thus resulting in significant energy savings. The module includes a brief description of the history, chemistry and manufacturing process for paper and is recommended for a descriptive inorganic class. A comparison and evaluation of the two bleaching processes is also included and may be appropriate for an advanced inorganic course describing oxidizing agents or the effect of substituents on organometallic redox reactions. The module includes a list of ten questions, "Notes to Instructors" and a PowerPoint presentation.
