Glucose and fructose are widely available and renewable resources. They were used to prepare acetic acid (AA) under the catalysis of potassium acetate (KAc) by thermogravimetric anal. and pyrolysis coupled with gas chromatog. and mass spectrometry. The TGA result showed that the KAc addition lowered the glucose’s thermal decomposition temperatures (about 30°C for initial decomposition temperature and 40°C for maximum mass loss rate temperature), implying its promotion of glucose’s decomposition The Py-GC/MS tests illustrated that the KAc addition significantly altered the composition and distribution of hexose pyrolysis products. The maximum yield of AA was 52.1% for the in situ catalytic pyrolysis of glucose/KAc (1:0.25 wt/wt) mixtures at 350°C for 30 s. Under the same conditions, the AA yield obtained from fructose was 48% and it increased with the increasing amount of KAc. When the ratio reached to 1:1, the yield was 53.6%. In comparison, a study of in situ and online catalytic methods showed that KAc can not only catalyze the primary cracking of glucose, but also catalyze the cracking of a secondary pyrolysis stream. KAc plays roles in both phys. heat transfer and chem. catalysis. The experimental process involved the reaction of 3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9Application of 19444-84-9)
3-Hydroxydihydrofuran-2(3H)-one(cas: 19444-84-9) is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde. And it may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis.Application of 19444-84-9
