Alkanoic acid (V): A portion of fractions J-L, pooled (16.22 g), purified by preparative TLC (solvent mixture: heptane: benzene: ethanol, 100:100:1 v/v), yield- 313 mg, [R.sub.f][approximately]0.48, mp 68-71[degrees]C, [C.sub.26][H.sub.52][O.sub.2] crystallized with ethyl acetate-chloroform as white granules, brownish colour on TLC with Sb[Cl.sub.3] spraying reagent, did not give colour with TNM.
We identified [C.sub.18:0] [omega]-(o-alkylphenyl) alkanoic acids, which may be derived from plants or aquatic resources, as well as phytanic acid (from ruminant or aquatic) and cholesterol derivatives (from animal).
Proper dispersion of nanoparticles into the polymer matrix can be achieved through either chemical or electrochemical treatment where modifying agents, such as silane, polyacrylicacid, polystyrene, polymethylmethacrylate, long-chain fatty acids (stearic acid, oleic acid, etc.), silane coupling agents, alkanoic acids, etc., are employed to modify the surface of the nanoparticles.
