So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Jo, Donghyun; Lee, Jae Sung; Lee, Kyung Hee researched the compound: (S)-Methyl 3-hydroxybutanoate( cas:53562-86-0 ).COA of Formula: C5H10O3.They published the article 《Enantio-differentiating hydrogenation of methyl acetoacetate over modified nickel catalysts: Effects of nickel dispersion on the enantio-selectivity of catalysts》 about this compound( cas:53562-86-0 ) in Research on Chemical Intermediates. Keywords: nickel silica hydrogenation catalyst enantioselectivity tartaric acid reduction temperature; methyl acetoacetate hydrogenation enantioselectivity catalyst malic acid sorption. We’ll tell you more about this compound (cas:53562-86-0).
Enantio-differentiating hydrogenation of Me acetoacetate was performed over fumed silica-supported Ni catalysts modified with solution of (R,R)-tartaric acid or (S)-malic acid and NaBr. The reduction temperature of supported Ni was the most important factor determining the enantioselectivity of catalysts. The reduction temperature affected Ni dispersion, quantity, and coverage by the agent. The enantioselectivity (ee) of (R,R)-tartaric acid and (S)-malic acid was compared at various reduction temperatures (R,R)-tartaric acid, with two hydroxyl groups, showed optimum coverage on Ni surface and maximum ee of 72% at reduction temperature of 973 K. In contrast, (S)-malic acid with one hydroxyl group showed monotonous decrease in ee and decreasing adsorbed amount with increasing reduction temperature
In some applications, this compound(53562-86-0)COA of Formula: C5H10O3 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
