catalyzed reactions between iodine and cresols microdetermination of cresols

ABSTRACT

The oxidation of three isometric cresols with iodine in potassium iodide solutions in the presence and in absence of silver ions as a catalyst was investigated and used for microdetermination of these vital reductants. The study of these redox reactions and microdetermination of the methylphenols was performed by volumetric and spectrophotometric methods. The spectrophotometric method was more accurate than potentiometric and volumetric and can be used for determination of these reductants in microrange [4 to 240 ug]. The volumetric methods used silver ions as catalysts. Possible schemes for the course of the redox reactions were suggested. One and two electron processes for oxidation of cresols have been indicated
