Abstract
U ovome radu su sintetizirani i pročišćeni polimerni aditivi. Prilikom sinteze svih polimernih aditiva korišteni su monomeri metil metakrilat (MMA), dodecil metakrilat (DDMA) i oktadecil metakrilat (ODMA), te ovisno o odabranome polimernome sustavu, funkcionalni monomer tert-butilaminoetil metakrilat (TBAEMA), 2-(diizopropilamino)etil metakrilat (DIPOAEMA) ili 2-(dietilamino)etil metakrilat (DEAEMA). Struktura i čistoća polimernih aditiva potvrđena je korištenjem spektroskopskih metoda infracrvene spektroskopije s Fourierovom transformacijom i protonske nuklearne magnetske rezonancije. Polimeri su podvrgnuti diferencijalnoj pretraženoj kalorimetriji i kromatografiji isključenja, kako bi im se odredila toplinska svojstva i prosječna molekulska masa polimera. Za ispitivanje svojstava formulacija s dizelskim i biodizelskim gorivom, pripravljene su formulacije goriva s 2000 ppm polimernih aditiva. Formulacije su analizirane uz pomoć diferencijalne pretražne kalorimetrije i proučavana je promjena morfologije kristala optičkim mikroskopom s polarizacijom. Određene su točke filtrabilnosti i tecište prema standardnim metodama EN 116 za točku filtrabilnosti i ASTM D5950 za tecište. Dobiveni rezultati pokazali su sniženje temperature tecišta i filtrabilnosti dizelskom gorivu kod svih sintetiziranih polimernih aditiva, a najbolji rezultat pokazao je sustav MDO30-1:1-DEA10 koji je snizio vrijednost točke filtrabilnosti dizelskoga goriva od -8 °C do -18 °C te vrijednost tecišta od -18 °C do -45 °C.
Abstract (english)
In this paper, polymer additives were synthesized and purified. Monomers methyl methacrylate (MMA), dodecyl methacrylate (DDMA) and octadecyl methacrylate (ODMA) were used in the synthesis of all polymer additives, and depending on the selected polymer system, functional monomer tert-butylaminoethyl methacrylate (TBAEMA), 2-(diisopropylamino)ethyl methacrylate (DIPOAEMA) or 2-(diethylamino)ethyl methacrylate (DEAEMA). The structure and purity of polymer additives was confirmed using fourier transform infrared spectroscopy methods and proton nuclear magnetic resonance. Polymers underwent differential scanning calorimetry and exclusion chromatography, to determine their thermal properties and average molecular weight of polymers. For testing the properties of diesel and biodiesel fuel formulations, fuel formulations with 2000 ppm polymer additives were prepared. Formulations were analyzed with the help of differential scanning calorimetry and the change in crystal morphology by optical microscope with polarization was studied. The filtrability points and flow according to the standard methods are EN 116 for the cold filter plugging point and ASTM D5950 for the pour point. The obtained results showed a decrease in the temperature of the liquid and filtrability of diesel fuel in all synthesized polymer additives, and the best result was shown by the MDO30-1:1-DEA10 system, which lowered the value of the cold filter plugging point of diesel fuel from -8 °C to -18 °C and the pour point liquid from -18 °C to -45 °C.
