Preparation of hydrated glucose by low-temperature crystallization was written by Arkhipovich, N. A.;Petrushevskii, V. V.;Bondar, E. G.. And the article was included in Sakharnaya Svekla in 1969.Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate This article mentions the following:
To obtain a good yield of glucose the initial upper crystallization temperature should be 35-8°. Over a period of 4.5 days, the yield of hydrated glucose from 100 g. syrup increases steadily, rising to 29 g., while the absolute crystallization rate falls, reaching 1.83 mg./m.2/min. at the end of the process. To obtain a good glucose yield combined with good massecuite quality, the syrup saturation should be the maximum possible consistent with the min. amount of “powder.” In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate).
(2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate (cas: 14431-43-7) belongs to tetrahydropyran derivatives. Tetrahydropyrans and furans principally constitute as a central motif in diverse medicinally privileged molecules. One classic procedure for the organic synthesis of tetrahydropyran is by hydrogenation of the 3,4-isomer of dihydropyran with Raney nickel.Quality Control of (2S,3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol hydrate
