The interesterification reaction of palm oil and methyl acetate to produce methyl ester and triacetin was conducted with biocatalysts of aromatic compounds, namely eugenol and cajuput oil. Aromatic compounds are the most efficient catalysts in the manufacturing process of biodiesel, leading to improved quality. Therefore, this study aimed to obtain a more effective and efficient biodiesel production process, with fewer procedural steps, in order to reduce production costs.

We propose new structures of metal-containing azopolymers with changeable electro-optical properties depending on different length spacers. The new monomers – 4-{4-[4-(methacroyloxy)butoxy)phenyl]diazenyl benzoic acid, 4-{4-[4-(methacroyloxy)octyl)oxy]phenyl}diazenyl] benzoic acid and their complexes with Co and polymers based on these ones were synthesized. The influence of the electric field on the absorption spectra of new metal-containing azopolymers was investigated.
