In the present work, a new modified method is used for the measurement of iodine value, wherein mercuric acetate as catalyst is directly used in the powder form in the process of determination without changing the operational steps of the wijs standard method. The analytical results obtained with this standard method compared with those from modified wijs method. The modified determination method can make the determination reaction finished in 3 minutes. An attempt has been made to reduce the time of the Wijs method by use of mercuric acetate as a catalyst/accelerator. The iodine value of extracted oils of different groundnut seeds varieties such as RS-1(Rs-1),TAG-3a(Tg-3a),TAG-51(Tg-51),K-6(K-6), Uf70-130, K-1, K-3 and Rsb-103-87 were determined by regular Wijs method for 30 minutes whereas when we apply catalytic Wijs method with use of 2 mg, 5 mg and 10 mg of mercuric acetate to perform as catalyst then it is reducing the time of analysis to 3 minutes. When catalyst is used the different values obtained for coefficient of variations are 0.31 for 2mg, 0.34for 5mg and 0.34for 10 mg whereas 0.25 for non-catalyst addition. The results obtained in the present work shows Tg-51and Tg-3a have more % difference in IV in case of 2mg. The standards mean error in the range of 0.16-0.18.
