Stepwise partition of a mixture of hexa‐ (C16:1ω7), hepta‐(C17:1ω8), and octadecenoic (C18:1ω9) acids was thoroughly investigated. The efficiency of different rates of three fractionation procedures (i.e., fatty acid crystallization from acetone or fatty acid pared. Fatty acid urea adducts formation is best suited for stepwise removal of the bulk of C18:l (accumulated in the crystals) and C16:l as well as small quantities of C18:l (both being removed in the filtrates). Whatever the technique, high crystallization rates were more efficient.
