| 1 | Recent advances in catalytic production of sugar alcohols and their applications显示文摘Conversion of non-edible biomass into fuels and value-added chemicals has achieved great attention to cope the world's energy requirements. Lignocellulose based sugar alcohols such as sorbitol, mannitol, xylitol, and erythritol can be potentially used as emerging fuels and chemicals. These sugar alcohols can be converted into widely used products(e.g. polymer synthesis, food and pharmaceuticals industry). The heterogeneous catalytic production of sugar alcohols from renewable biomass provides a safe and sustainable approach. Hydrolysis, coupled with hydrogenation and hydrogenolysis has been proved to be more effective strategy for sugar alcohols production from biomass. This review summarizes the recent advances in biomass upgrading reactions for the production of sugar alcohols and their comprehensive applications. | Bakht Zada Mengyuan Chen Chubai Chen Long Yan Qing Xu Wenzhi Li Qingxiang Guo Yao Fu | 2017 | Science China Chemistry2017，60，7： | 3 |
| 2 | Theoretical and experimental study on lipophilicity and wound healing activity of ginger compounds显示文摘Objective:To correlate the chromatographic and computational method to calculate lipophilicity of selected ginger compounds and to observe the effects of log P on wound healing.Methods:Mixtures of acetonitrile and water with acetonitrile content between 95%and 50%v/v in 5%increments were kept separately in 10 different chromatographic chambers,saturated with solvent for 2 h.Spots were observed under UV light atλ=254 nm p-anisaldehyde used as a spraying reagent Theoretical calculation was done using the Alogps 2.1 online program at www.vcclab.org/lab/alogps.For percentage wound contraction,five groups of animal(mice)(25-30 g)of either sex were selected.Wound were created on dorsal surface of animals using toothed forceps,scalpel and pointed scissors.The wound areas were calculated using vernier caliper.After making wound mice were orally administered 35 mg/kg 6-shogoal,6-gingerol,8-gingerol and 10-gingerol respectively.Croup E as the control group received tap water.Results:The Iipophilicity values determined in thin layer chromatography were correlated with the theoretically calculated various log P by linear regression analysis.Significant correlations were found between log P values calculated by software program and the experimental reversedphase thin-layer chromatography data.Order of wound healing property of ginger compounds is directly dependent on lipophilieity i.e.more lipophilic compound has highest activity.Conclusions:Experimentally determined lipophilieity(R_(MO))values were correlated with log P determined by software's and found satisfactory.Lipophilieity(R_(MO)is a useful parameter for the determination and prediction of biological activity of ginger compounds. | Mohammed Afroz Bakht Mohammed F.Alajmi Perwez Alam Aftab Alam Prawez Alam Tariq Mohammed Aljarba | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，4： | 2 |
| 3 | Effective conversion of cellobiose and glucose to sorbitol using non-noble bimetallic NiCo/HZSM-5 catalyst显示文摘The tandem hydrolysis and hydrogenation of saccharides into sorbitol is an especially attractive reaction in the conversion of biomass. Here, an economical and efficient bimetallic catalyst for the transformation of glucose and cellobiose into sorbitol is reported. Non-precious metal based catalysts such as NiCo, Ni, and Co, were prepared via modified impregnation method, and NiCo/HZSM-5 showed superior performance for the synthesis of sorbitol(86.9% from cellobiose, 98.6% from D-glucose).Various characterizations, such as Brunner-Emmet-Teler(BET), X-ray diffraction(XRD), transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS), confirmed that NiCo alloy formed and highly dispersed in NiCo/HZSM-5 catalyst. The high performance of fabricated catalyst would be attributed to the formation of nickel-cobalt alloy over HZSM-5 zeolite surface. High temperature and H_2 pressure were favorable for the tandem hydrolysis and hydrogenation reaction. Besides,the reaction pathway was also proposed based on the kinetics study. Cellobitol was detected as the intermediate in the reaction mixture. Furthermore, in the catalytic stability study, it was found that active metal species of NiCo/HZSM-5 were stable. The deactivation of catalyst would be due to the covering of acidic sites over NiCo/HZSM-5. | Bakht Zada Long Yan Yao Fu | 2018 | Science China Chemistry2018，61，9： | 2 |
