5-Aminosalicylic acid (5-ASA)is currently prepared by electrochemical reduction of 5-nitrosalicylic acid(5-NSA)in acidic media.In this work,electrolytic reduction of 5-NSA in alkaline media is presented.Reaction conditions and parameters such as anode and cathode electrodes,electrolyte type, reaction time,temperature,current,and the pH for isolation of product are investigated.The yield of the reaction was 90.9%and the melting point was 280 °C with decomposition .The UV-Vis and FT-IR spectra of the product was in good agreement with the standard material.The elemental analysis of the product was almost the same as the standard.

Key Words: 5-aminosalicylic acid,5-nitrosalicylic acid,electrochemical synthesis, elemental analysis,reduction.
