Refined and deodorized rapeseed oil was hydrogenated using Girdler nickel catalyst at a starting temperature of 140 C and at 25 and 30 psig hydrogen gas pressures. The studies revealed that the hydrogenation was more effective, as determined by rate of decrease in iodine value (Wi js) and increase in the melting point, at 25 psig than at 30 psig. The rate of effectiveness was, however, not significant. The rate of hydrogenation was compared to cottonseed oil subjected to hydrogenation under identical conditions. Cottonseed oil showed a better, though insignificant, rate of increase in melting point per unit increase in time.
