Abstract
Vedno več je povpraševanja po HMF-ju, saj je to ena izmed spojin, ki predstavlja velik pomen pri iskanju alternativnih virov energije. HMF je možno pretvoriti v nekaj zelo pomembnih kemikalij visokih vrednosti. Ena izmed teh je tudi levulinska kislina, ki se uporablja v različne namene, vendar je pretvorba HMF-ja do kisline zelo nizko donosna, proizvodni stroški pa so ogromni. Cilj je bil raziskati stabilnost HMF-ja v različnih topilih, relevantnih predvsem za njegovo sintezo in čimbolj optimalno nadaljnjo pretvorbo, saj bi tako zmanjšali število organskih odpadkov v laboratorijih oziroma industrijskih proizvodnjah in s tem omogočili boljši celokupni izkoristek stranskih produktov. Prišel sem do ugotovitve, da je HMF-najbolj stabilen v vodi in ima najbolj učinkovito pretvorbo z katalizatorjem H-beta zeolitom.

Title:Stability of hydroxymethylfurfural in water and various organic solvents and its conversion towards levulinic acid
Abstract:
There is a growing demand for HMF, as it is one of the compounds that is of great importance in the search for alternative energy sources. HMF can be converted into some very important high value chemicals, one of which is levulinic acid, which is used for a variety of purposes, but the conversion of HMF to acid is very low yielding and the production costs are enormous. The aim was to investigate the stability of HMF in different solvents, mainly relevant for its synthesis and to optimise its further conversion, as this would reduce the organic waste in laboratories or industrial production and thus allow a better overall recovery of the by-products. I came to the conclusion that HMF is most stable in water and has the most efficient conversion with the catalyst H-beta zeolite.

Keywords:5-hydroxymethylfurfural, levulinic acid, catalysis
