Furan derivatives such as 5-hyroxymethylfurfural (HMF) which derived from the acid-catalyzed dehydration of carbohydrates, are used as precursor in the production of biofuels and bioplastics. Therefore, studies towards the use of cellulosic wastes and monosaccharides for HMF production, are increasing day by day. In many studies carried out, it has been determined that fructose is the sugar which has the highest percentage of conversion. For this purpose, in this study it is investigated that HMF production from waste coke with high fructose content. Conversion of fructose to HMF was performed in acidic biphasic environment at 150 oC under high pressure. HMF concentration was determined by HPLC, the reducing sugar concentration was determined by dinitrosalicylic acid (DNS) method. According to this, in the waste coke conversion percentage of sugar obtained as 96.29, HMF productivity as 67.26% and HMF selectivity as 69.85%, in media saturated with NaCl, containing DMSO. As a result by this study it is shown that HMF which is necessary for production both liquid biofuel and biodegredable plastic, can be produced with high productivity from waste drinks which have high fructose content

Karbonhidratların asit katalizli dehidrasyonundan elde edilen 5-Hidroksimetilfurfural (HMF) gibi furan türevleri, biyoyakıt ve biyoplastik üretiminde öncül madde olarak kullanılır. Bu nedenle selülozik atıklar ve monosakkaritlerin HMF üretiminde kullanılmasına yönelik çalışmalar gün geçtikçe artmaktadır. Yapılan birçok çaışmada dönüşüm yüzdesi en yüksek olan şekerin fruktoz olduğu belirlenmiştir. Bu amaçla bu çalışmada fruktoz içeriği yüksek olan atık koladan HMF üretimi incelenmiştir. Fruktozun HMF’ye dönüşümü asidik bifazik ortamda 150 °C’de yüksek basınçta gerçekleştirilmiştir. HMF konsantrasyonu HPLC ile, dönüşmeyen şeker konsantrasyonu ise Dinitrosalisilik asit (DNS) yöntemi ile belirlenmiştir. Buna göre atık kolada şekerin dönüşüm yüzdesi 96.29, HMF verimliliği % 67.26 ve HMF seçiciliği ise %69.85 ile NaCl ile doyurulmuş, DMSO içeren ortamda elde edilmiştir. Sonuç olarak bu çalışma ile fruktoz içeriği yüksek olan atık içeceklerden hem sıvı biyoyakıt hem de biyobozunur plastik üretimi için gerekli HMF’nin yüksek verimlilikle üretilebileceği gösterilmiştir.
