Preferred phase-transfer catalysts include quaternary ammonium and phosphonium salts, polyethylene glycols and derivatives of polyethylene glycols.

Method for isolating oleic acid and producing linoleic dimer/trimer acids via selective reactivity (Difranco, E., Arizona Chemical Company, Jacksonville, Florida, US 6835324, Issued December 28, 2004).

Polyunsaturated fatty acids from tall oil are conjugated and selectively polymerized in the presence of oleic acid. The fatty acids are treated with iodine (0.01–0.15%) and the mixture is heated to conjugate the polyunsaturated components. A co-catalyst (iron complexes, iron powder or bromine) may be further added to the mixture to enhance the conjugation of the polyunsaturates. Separation techniques are employed to isolate oleic acid and the linoleic acid-based dimer/trimer acids produced. A C-36/C-54 product which is useful in a number of applications including polyamide and polyester production is obtained.
