Rapeseed oils with different erucic acid contents have been hydro‐genated in a “dead‐end” type of laboratory reactor with Adkins‐type copper‐chromite catalyst. It was observed that, as is true with oleic acid, erucic acid is not hydrogenated by this catalyst, but it differs in that positional or geometrical isomerization does not occur. The presence of erucic acid does not change the mechanism of hydrogenation of rapeseed oils in a range of concentrations of this acid. On the other hand, it markedly influences the rate of reaction.
