A model GM (grey model) (1,1) for forecasting the rate of copper extraction during the bioleaching of primary sulphide ore was established on the basis of the mathematical theory and the modeling process of grey system theory. It was used for forecasting the rate of copper extraction from the primary sulfide ore during a laboratory microbial column leaching experiment. The precision of the forecasted results were examined and modified via "posterior variance examination". The results show that the forecasted values coincide with the experimental values. GM (1,1) model has high forecast accuracy; and it is suitable for simulation control and prediction analysis of the original data series of the processes that have grey characteristics, such as mining, metallurgical and mineral processing, etc. The leaching rate of such copper sulphide ore is low. The grey forecasting result indicates that the rate of copper extraction is approximately 20% even after leaching for six months. 展开更多

Two 1-methyl-1H-benzo[d]imidazole derivatives, C_(18)H_(14)CuN_4O_4·C_4H_8O_2(1) and C_9H_9N_3O(2), have been synthesized and characterized by NMR, MS, FT-IR, elementary analysis and X-ray single-crystal ... Two 1-methyl-1H-benzo[d]imidazole derivatives, C_(18)H_(14)CuN_4O_4·C_4H_8O_2(1) and C_9H_9N_3O(2), have been synthesized and characterized by NMR, MS, FT-IR, elementary analysis and X-ray single-crystal diffraction. Compound 1 crystallizes in monoclinic, space group P2_1/n with a = 9.6888(3), b = 7.3772(2), c = 14.3277(4)A, β = 95.819(3)°, V = 1018.81(5) A3, M_r = 501.98, Z = 2, D_c = 1.636 g/cm^3, F(000) = 518, μ = 1.123 mm^(-1), MoKα radiation(λ = 0.71073 A), the final R = 0.0325 and wR = 0.0859 for 1821 observed reflections with I 〉 2σ(I). Compound 2 crystallizes in monoclinic, space group C2/c with a = 14.2908(14), b = 14.4268(13), c = 8.4802(6) A, β = 108.513(9)o, V = 1657.9(3) A3, M_r = 175.19, Z = 8, D_c = 1.404 g/cm^3, F(000) = 736, μ = 0.097 mm^(-1), Mo Kα radiation(λ = 0.71073 A), the final R = 0.0563 and wR = 0.1531 for 1231 observed reflections with I 〉 2σ(I). Intermolecular(N-H···N, N-H···O) and intramolecular(N-H···N, C-H···O) hydrogen bonds, as well as C-H···π and π-π stacking interactions, help to stabilize the crystal structure of compound 2. 展开更多
