Abstract
U ovom radu opisana je sinteza i metoda pročišćavanja četiri bioaditiva reakcijom esterifikacije između galne kiseline i odgovarajućega alkohola. Alkoholi koji su korišteni za reakcije su etanol, propanol, butanol i pentanol, a kao katalizator korišten je p-toluen sulfonska kiselina. Sintetizirani produkti pročišćeni su ispiranjem s vodom. Struktura i čistoća priređenih spojeva analizirana je spektroskopskim metodama infracrvene spektroskopije s Fourierovom transformacijom i protonskom nuklearnom magnetskom rezonancijom. Produkt je detaljnije analiziran pomoću metoda diferencijalne pretražne kalorimetrije i kromatografije isključenja po veličini. Nadalje, promatrala se topljivost produkata u vodi, dimetilsulfoksidu i dizelskome gorivu. Ustanovljeno je da sintetizirani produkti nisu topljivi u dizelskokome gorivu zbog čega se antiokisdativno djelovanje bioditiva ne može odrediti. Iz svih provedenih analiza može se zaključiti da su produkti sintetizirani, ali s jako malim iskorištenjem.
Abstract (english)
This paper describes the synthesis and purification method of four bioadditives through the esterification reaction between gallic acid and the corresponding alcohol. The alcohols used for the reactions were ethanol, propanol, butanol, and pentanol, with p-toluenesulfonic acid used as the catalyst. The synthesized products were purified by rinsing with water. The structure and purity of the prepared compounds were analyzed using spectroscopic methods such as Fourier-transform infrared spectroscopy and proton nuclear magnetic resonance. The synthesized product was further analyzed using differential scanning calorimetry and size-exclusion chromatography. Additionally, the solubility of the products in water, dimethyl sulfoxide, and diesel fuel was observed. It was established that the synthesized products were not soluble in diesel fuel, making it impossible to determine their antioxidative properties. From all conducted analyses, it can be concluded that the products were synthesized but with very low yield.
