摘要：

Time required for hydrogenation of soybean and rapeseed oils to 1-2% linolenate content with a copper chromite catalyst is reduced 40-60% if the dead-end system is replaced with a procedure using a flow of hydrogen through the reactor. The effect is ascribed to the removal of oxidation products, acting as catalyst poisons and the water which is formed during reduction of the catalyst. Selectivity towards the linolenate compound is nearly unchanged. © 1979 The American Oil Chemists' Society.
