Iodine Value
Free Fatty Acid Moisture 'benty-seven experiments were done to study the hydrogenation characteristics of high erucic rapeseed oil, with the experiments being designed systematically according to orthogonal test. The characteristics include the influence of operating variables on the reaction rate (average reaction rate and instantaneous reaction rate) and on the relationship between melting point and iodine value of the finished product, and the induction time of reactions under different conditions. Reaction rate and melting point models were generated from the experimental data. The results show that temperature has the most significant effect on the reaction rate, followed by catalyst concentration and hydrogen pressure. The correlation between melting point and iodine value of the hydrogenated product was greatly affected by the operating variables, especially temperature. Melting point will decrease as temperature increases at a given iodine value. Induction time is relatively long at temperature below 170T.
