Japanic acid (C22 acid), a main constituent of dibasic acid portion in japan wax, and palmitic acid were reacted to form monomolecular-type glycerides ; α-, α'-japanin-β-palmitin and α-, β-japanin-α'-palmitin of those melting points were 61.2 and 68.3°C, respectively. Japanic acid used in this work was a pure material of which synthetic procedure has been reported previously.
