Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol, is researched, Molecular C7H14O6, CAS is 1824-94-8, about Beneficial Effect of Water on the Catalytic Conversion of Sugars to Methyl Lactate in Near-Critical Methanol Solutions.Reference of (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol.
Biomass comprises a certain amount of water, which affects the reactions in organic solutions Generally, water facilitates the hydrolysis of Me lactate resulting in a decrease of the yield. However, we observed that a certain water content is beneficial for the production of Me lactate on the conversion of sugars with NiO as a catalyst in near-critical methanol solutions With water, glycolaldehyde di-Me acetal, the main side product, was hydrolyzed to glycolaldehye. Glycolaldehye could be transformed to sugars via the aldol condensation at relative higher temperatures, and the sugars were subsequently converted to Me lactate. NiO could be regenerated by calcination, and water showed almost no adverse effect on the activity of NiO catalyst. The beneficial effect of a certain water content showed a great potential for the direct production of Me lactate from raw biomass materials without drying.
After consulting a lot of data, we found that this compound(1824-94-8)Reference of (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol can be used in many types of reactions. And in most cases, this compound has more advantages.
