A new process has been developed, in which the cyclopropenoid groups in cottonseed oil can be selectively and continuously hydrogenated under mild conditions. This process utilizes nickel in a fixed‐bed reactor, thereby eliminating the ex‐pensive filtration commonly associated with slurry reactors. In pilot‐plant runs at essentially atmospheric pressure and at temperatures from 150 to 315P (66‐157C), Halphen‐negative oils were produced in as short a contact time as 2 min. Little or no hydrogenation or isomerization of normal fatty acids occurred during the process. Reaction rate data indicate that cyclopropenoid removal follows first‐order behavior.
