It is of importance to convert glycerol,the primary by-product from biodiesel manufacturing,to various valuable C3 chemicals,such as acrolein via dehydration,lactic acid,1,3-dihydroxyacetone via oxidation,and 1,3-propanediol,allyl alcohol via hydrogenolysis.As compared to petroleum-based resources,C3 chemicals from glycerol provide a benign,sustainable and atomically economic feature.Extensive heterogeneous catalysts have been designed,prepared and tested for these transformations.In recent five years,great progress,including high yields to target products over appropriate catalysts,insight into reaction mechanism and network,has been achieved.The present review systematically covers recent research progress on sustainable C3 chemical production from catalytic glycerol transformations.We hope that it will benefit future research on transformations of glycerol as well as other polyols.

A series of Cu-Mg-Al hydrotalcites derived oxides with a(Cu+Mg)/Al mole ratio of 3 and varied Cu/Mg mole ratio(from 0.07 to 0.30) were prepared by co-precipitation and calcination methods, then they were introduced to the hydrogenation of furfural in aqueous-phase. Effects of Cu/Mg mole ratio, reaction temperature, initial hydrogen pressure, reaction time and catalyst amount on the conversion rate of furfural as well as the selectivity toward desired product cyclopentanol were systematically investigated. The conversion of furfural over calcined hydrotalcite catalyst with a Cu/Mg mole ratio of 0.2 was up to 98.5% when the reaction was carried out under 140 ?C and the initial hydrogen pressure of 4 MPa for 10 h, while the selectivity toward cyclopentanol was up to 94.8%. The catalysts were characterized by XRD and SEM. XRD diffraction of all the samples showed characteristic pattern of hydrotalcite with varied peak intensity as a result of different Cu content. The catalytic activity was improved gradually with the increase of Cu component in the hydrotalcite.

Guaiacol was chosen to represent O-containing chemicals with lower effective hydrogen carbon ratio（H/Ceff factor） in bio-oil,and the hydrodeoxygenation of guaiacol was investigated over non-precious and nonsulfided catalysts. Effects of metal composition,reaction temperature,and hydrogen pressure on conversion and selectivity were investigated systematically. Among various compositions of catalysts,Ni Co/CNT exhibited best performance of guaiacol conversion with higher selectivity towards desired alcohols with higher H/Cefffactor. The reaction pathways of guaiacol in aqueous were proposed based on the product analyzed.Results show that metal composition and temperature have great effects on the conversion of guaiacol and the yields of desired products.

Zirconia-loaded sulfuric acid （SO2-/ZrO2） catalysts were prepared by impregnation method, molded by punch tablet machine and characterized by X-ray diffraction. SO4^2-/ZrO2 catalyst was used to obtain glycerol triacetate （GTA） directly from glycerin. The effect of some factors, such as different temperatures of calcination and catalysts molded or not, on the reusable times of catalysts and the yield of GTA were investigated. The optimum reaction conditions were shown as follows： the reaction temperature was 403 K; the reaction time continued for 8 h; the amount of molded catalysts was 5 wt% of glycerin and the molar ratio of glycerin to acetic acid was 1 ： 8. The yield of GTA was 97.93% under the optimum condition.

The present study aimed to investigate the effect of NVPEP800,a novel heat shock protein(Hsp)90 inhibitor of the 2minothieno[2,3]pyrimidine class,in combination with radiation on glioblastoma cells.T98Ghuman glioblas-toma cells were treated with dimethyl sulfoxide(DMSO),NVPEP800,NVPEP800 in combination with Xay irradiation(10Gy,20min),or Xay irradiation only,and cultured for 40h.Cell viability was measured upon comple-tion of the treatments.In addition,apoptosis was measured and immunoblot analysis was performed to analyze the expression levels of cellular protein inhibitoryκB kinaseβ(IKKβ).The combined treatment with NVPEP800 and Xay irradia-tion resulted in the synergistic destruction of malignant cells.Furthermore,NVPEP800 significantly induced apoptosis in the human glioblastoma cells.The immunoblot analysis data indicated that NVPEP800 markedly reduced the expression level of IKKβ.The results also revealed that Xay irradiation significantly attenuated the increase in the level of Hsp70 in cells treated with NVPEP800.Since elevated levels of Hsp70 are associated with drug resistance induced by Hsp90 inhibitors,the effects of Xay irradiation on Hsp70 levels may be associated with the enhanced effect on cells of the presence of irradiation.The results of the current study suggest that irradiation enhances the inhibitory effect of NVPEP800 on the proliferation of malignant glioblastoma cells by downregu-lating the expression level of cellular signaling protein IKKβand attenuating the upregulation of Hsp70 that is induced by NVPEP800.
