摘要：

The influence of pressure on hydrogenation is investigated between 2-20 atm. The relationship between rate of reaction and pressure is complex, with a maximum rate at 6 atm in the pressure range below 14 atm. This is because catalyst reduction is simultaneous with fat hydrogenation. Accumulation of conjugated dienes is measured and a suggested mechanism is presented. © 1979 The American Oil Chemists' Society.
