Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 585-88-6, Name is Maltitol, molecular formula is , belongs to Tetrahydropyrans compound. In a document, author is Karnjanakom, Surachai, Product Details of 585-88-6.
Facile In Situ 5-EMF Synthesis and Extraction Processes from Catalytic Conversion of Sugar under Sustainable Long-Life Cycle
The catalytic behavior for 5-ethoxymethylfurfural (5-EMF) formation was systematically studied via facile conversion of sucrose under a sustainable ultrasonic-biphasic system using an active ZnO nanofiber-deposited-SO3H-carbon catalyst (Zn-S-C). Interestingly, 5-EMF with a high yield could be easily obtained and separated from ethanol/tetrahydrofuran (THF) via green synthesis-extraction procedures in the presence of NaCl. Meanwhile, an actual 5-EMF yield of 93.5 +/- 0.8% was successfully achieved at 98 degrees C for 47 min using a THF amount (0.25 mol) and catalyst adding amount (77.8 wt %) over the combination of 2(k) factorial and Box-Behnken designs. The product selectivity and yield from sucrose conversion were systematically controlled by adjusting type/amount of catalyst, co-solvents or inorganic salts, and ultrasonic system. The activation energy (38.17 kJ/mol) obtained from ultrasound-assisted conversion of sucrose into 5-EMF was lower than that from the conventional system. Strikingly, a nonsignificant decrease in the turnover rate (TOR, min(-1)) for conversion of sucrose into 5-EMF appeared when the catalyst was reused up to 100 cycles, indicating long-life cycle stability of the as-prepared catalyst.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 585-88-6, in my other articles.
