Abstract

Jodni broj se koristi za kvantifikovanje dvostrukih veza, glavnih uzroka nestabilnosti biodizela. Položaj i broj dvostrukih veza po molekuli su važan faktor za stabilnost biodizela a jodni broj ne može razlikovati ove parametre. Danas, sastav i molekulska struktura raznih ulja, sirovina za biodizel su jasno identifikovani. Stoga, jodni broj bi bio koristan za određivanje promjena u bazi ulja od degradacije. Rezultati starenja, mogu se mjeriti jodnim brojem, ukupan kiselinski broj, anisidna vrijednosti (aldehidi) i viskoznost. Povećani kiselinski broj je dokaz propadanja a ne mjera stabilnosti. Ove vrijednosti mogu samo kvantifikovati stepen degradacije, ali one nisu predvidjele stabilnost biodizela ili mješavine biodizela. Visoka kiselost je vezana za probleme korozije i stvaranja naslaga u motoru Cilj rada je prikazati značaj određivanja jodnog broja kod biodizela.
