Kinetic studies of a batch treatment of linseed oil to produce cyclic acids indicated that of a continuous process conducted in a flow‐through reactor and involving rapid heat‐up of reactants, followed by a short reaction time, might be feasible. Tests were conducted in a continuous system to examine the effects of flow rate (retention time), reaction temp, reaction system pressure and reagents on product yields. The reactant solution (linseed oil‐ethylene glycol‐sodium hydroxide) was pumped through an externally heated tube and discharged through a back‐pressure valve. Maximum cyclic acid yields based on wt of oil were 37% by the continuous method and 40.4% by the batch process when the feed was saturated with nitrogen, and 39.5% and 46.1% for the respective methods when the feed was saturated with ethylene. These differences may be offset by the advantages inherent in a continuous process.
