求熟知仪器的大神给指导下外文文献里面的仪器是什么？怕弄错了。 1）a flash column chromatography(eluent:hexanes/dichloromethane8:2gradually increasing to dichloromethane/ethyl acetate7/3)：快速柱色谱/柱层析(洗提液:己烷/二氯甲烷8:2逐渐增加到二氯甲烷/乙酸乙酯7/3???)？ 【原文：The product was purified by flash column chromatography(eluent:hexanes/dichloromethane8:2gradually increasing to dichloromethane/ethyl acetate7/3)】 【原文：The residue was purified by a flash column chromatography on silica gel ([ethyl acetate]/[hexane] = 1:10 (vol/vol))】. 2）jacketed reactor：玻璃反应釜or夹套反应器？；mineral spirits：溶剂油?； 【mixed with 120 m L of mineral spirits in a 1 L jacketed reactor】 3）freeze-pump-thaw cycles：这是什么仪器？ small glass tubes小玻璃管吗？ 【A，B，C, D, and small glass tubes were added to a two-neck glass tube, and then the solution was degassed by three freeze-pump-thaw cycles.】 4）HPLL measurements(CH3CN/water = 3:1 (v/v), flow rate: 1.0 mL/ min ), equipped with a Waters 2965 controller and a Waters 2487 detector：高效液相色谱仪(?)？ 【原文The molar ratios of 1–3 were evaluated by HPLC measurements (CH3CN/water = 3:1 (v/v), flow rate: 1.0 mL/ min ), equipped with a Waters 2965 controller and a Waters 2487 detector.】 5）【UV irradiation (200 W UV lamp with 330 nm bandpass filter in the range of 220–390 nm, a 330 nm light intensity at the sample was 0.0001 W/ cm2 ) 】：200W，UV灯通过范围在220~390nm的330nm带通滤波器，330nm光强度作用在试样上为0.0001w/cm2？？ 6）syringe：注射器？ 【原文The samples were extracted via syringe after specific reaction times to estimate time dependence of the reshuffling reaction】. 7） Soxhlet (dichloromethane)：索氏提取器？ 【原文The product was purified by Soxhlet (dichloromethane) extraction for 15 h】。 |
