585-88-6, Maltitol is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,585-88-6
20.0 g of maltitol was placed in a heat-dried 200 ml four-necked flask and purged with nitrogen, and 100 ml of dehydrated DMF was added and the temperature was raised to 90 C. To this solution, 3.0 g of methyl salicylate and 0.3 g of potassium carbonate (dried by being covered with a heat gun under reduced pressure) were added and reacted for 4 hours at 96 to 110 C under reduced pressure (125 to 155 mm Hg). After completion of the reaction, the reaction solution was concentrated under reduced pressure, ethyl acetate was added to the residue, and the mixture was refluxed for 1 hour. After cooling to room temperature, the precipitate was removed by filtration and concentrated under reduced pressure to obtain 3.5 g of a brown liquid. Unreacted raw materials were removed using a chromatographic separation apparatus (apparatus: Kprep (manufactured by YMC), developing solvent: methanol / ultrapure water = 50/50, flow rate: 10 ml / min) and the structural isomers were collectively collected & 1.4 g of light pink oil was obtained.
As the paragraph descriping shows that 585-88-6 is playing an increasingly important role.
