A NOVEL BIPHASIC ELECTROLYSIS METHOD FOR THE OXIDATION OF 4-METHYLBENZYL ALCOHOL BY IN-SITU GENERATED HYPOCHLOROUS ACID USING NACL AS ELECTRO CATALYTIC MEDIATOR

摘要

Objective: The objective of the present work is to investigatethe electrochemical oxidation of 4-methylbenzylalcohol to4-methylbenzaldehyde in the presence of water soluble electrocatalytic mediator sodium chloride with newly generated hypochlorous reactive species by biphasic electrolysis system. Methods: Optimization studies have been carried out on an undivided beaker-type cell. The various parameters of 4- methylbenzyl alcohol influencing the reactions such as current density, mediator, acid and solvent have been investigated.Comparative study has been carried out fo r chemical and electrochemical method. Results: The Chloride containing mediator showed 96% yield of 4-methylbenzaldehyde under biphasic electrolysis. HPLC analysis confirms the existence of High quality of the yield. The plausible mechanism for the chloride oxidation system is shown in scheme 2. Conclusion: The electrolysis was carried out with the passage 3F of electricity which showed the good yield of 96%4-methylbenzaldehyde may serve as a leads for further optimization
