An as-isolated sample of PCN-14 was immersed in methanol for 24 h, and the extract was decanted. Fresh methanol was subsequently added, and the crystals were allowed to stay for an additional 24 h to remove the nonvolatile solvates (DMF and H2O). The sample was collected by decanting and treated with dichloromethane similarly to remove methanol solvates. After the removal of dichloromethane by decanting, the sample was dried under a dynamic vacuum (<10-3 Torr) at room temperature (25 °C) overnight. Before the measurement, the sample was dried again by using the “outgas” function of the surface area analyzer for 4 h at 120 °C. 是翻譯成:樣品浸泡在甲醇溶液中24h,濾液被輕輕倒出,新鮮的甲醇又被加入,再放24h去除掉不易失去的溶劑(DMF和H2O),過濾溶液并且用二氯甲烷用同樣的方法去除掉甲醇溶劑分子,通過過濾除去二氯甲烷,樣品在真空25度(壓強(qiáng)<10-3)下干燥一整夜,測量之前,通過表面分析儀的“outgas”功能在120度下再干燥4h。 大家好,是這樣翻譯的嗎?還有就是這其中的過濾是普通過濾還是減壓過濾?謝謝大家 |
