Step-by-Step Hybrid Conversion of Glucose to 5-acetoxymethyl-2-furfural Using Immobilized Enzymes and Cation Exchange Resin

چکیده
An alternative to 5-hydroxymethyl-2-furfural (HMF), which is a promising furan derivative that can be used as starting material for the preparation of non-petroleum-derived polymeric materials from sugars, 5-acetoxymethyl-2-furfural (AMF). The less-hydrophilic acetyl group AMF has advantages over hydroxy HMF in terms thermal stability and isolation. In previous studies, fructose been along with lipases enzymatic synthesis AMF. this study, we designed hybrid system includes isomerization esterification glucose into For step-by-step conversion 1,6-diacetylfructose (DAF), glucose-isomerase immobilized lipase (Novozym 435) were enzymes. Furthermore, AMF, direct dehydration DAF was performed using cation exchange resin (Amberlyst 15), combined several industrial solvents, such dimethylsulfoxide (DMSO), acetonitrile (AN) dimethylformamide (DMF) order improve final yield determined best solvent conditions. While after single maximum 24%, an mixed dioxane DMS (9:1) achieved each 65% 15%. According these results, found addition aprotic polar solvents could affect reaction dramatically formation HMF.

Step by Step Conversion to Organic Agriculture
The procedure of conversion of a farm commonly consists of three steps. In a first step, it is recommended to collect information on appropriate organic farming practices. In a second step, the most promising organic practices should be tried out on selected plots or fields to get familiar with. In a third step, only organic procedures should be implemented in the entire farm. Support from an e...
