    摘要: The present invention provides organic dyes having a rigid donor and the process for producing the same. The organic dye has the structure of formula (i) or formula (ii), wherein r1 is selected from h or c1-c18 alkyl; r5 is selected from h, c1-c18 alkyl or c1-c18 alkoxy; r6 and r7 are independently selected from h, c1-c18 alkyl, c1-c18 alkoxyphenyl or c1-c18 alkylphenyl; x is selected from any one of the groups represented by formulae (a) to (d); y is selected from a group represented by formula (e) or formula (f); in the formula (e), r2 and r3 are independently selected from h, f, c1-c18 alkyl or c1-c18 alkoxyphenyl; r4 is selected from any one of the groups represented by formulae (g) to (i). The present invention also provides a dye-sensitized solar cell which has a dye layer made from said organic dyes and has a relatively high power conversion efficiency.

    摘要: A method for extracting and separating a rare-earth element. Cations and anions in a quaternary ammonium ionic liquid extractant, that is, 2-ethylhexyl phosphate mono-2-ethylhexyl acrylate trialkyl methyl ammonium and phosphate di(2-ethylhexyl) phthalate trialkyl methyl ammonium, react with rare-earth ions to form neutral complex molecules, also, a collaborative effect and a competitive effect are present between the cations and the anions in the quaternary ammonium ionic liquid extractant in a rare-earth element extraction process, the separation factor for the rare-earth element is thus increased. The method for extracting and separating the rare-earth element provides good interfacial phenomena in the extraction process, does not generate emulsification, obviates the need for extractant saponification, and provides increased separation factor for rare-earth elements, and particularly increased separation factor for heavy rare-earth elements. In addition, the rare-earth element extraction and separation method is of reduced extraction acidity, of reduced stripping acidity, and of reduced acid consumption.

    摘要: The present invention provides a chlorinated poly(propylene carbonate)/biomass composite material, comprising 3 wt % to 57 wt % of a chlorinated poly(propylene carbonate); 40 wt % to 94 wt % of a biomaterial; 2 wt % to 20 wt % of a rosin or a rosin derivative; 0 wt % to 1 wt % of an antioxidant; and 0 wt % to 5 wt % of a filler, wherein a sum of amounts of all components is 100 wt %. The chlorinated poly(propylene carbonate) functions as a binder, and plays an important role in the moisture resistance of the composite material. The rosin or the rosin derivative functions as a viscosifier and a lubricant, and can also improve the moisture resistance and mechanical property of the composite material. Under the synergistic effect of the above components, the composite material obtained in the present invention is excellent in both mechanical property and moisture resistance. Further, because the starting materials comprise a larger amount of biomass materials, the cost thereof is low, and because the starting materials contain no formaldehyde, benzene and the like, the material is environment friendly.
