  • crude : adj 1 天然的,未加工的。2 粗(制)的,低級的;未熟的,生的;生硬的;粗糙的,粗雜的,粗魯的。3 赤...
  • anthracene : n. 【化學】蒽。
  1. So benzene and dmf from the some solvents separate crude anthracene

    因此,從這些溶劑中選出苯和dmf來進行分離粗蔥。
  2. At 70c, dissolved time 60min, solvent ratio 125 : 50ml / g, the effect of benzene is best to separating phenanthrene of crude anthracene, phenanthrene content of crude anthracene is increased from 10. 3 % to 41. 7 %. at 120c, dissolved time 80min, the solvent ratio 75 : 30ml / g, the effect of dmf is best to separate carbazole from the compound of anthracene and carbazole, and in the high or common temperature when the compound is separated the solid content may be seen that anthracene content is almost. so, the common temperature is selected in the filtration of the experiment

    苯在70 』 c 、溶解時間60min 、溶劑比125 : 5oml / g ,對分離粗蔥中菲的效果最好,可以使粗蔥中菲的含量從10 . 3 %提到41 . 7 % 。 dmf在120 』 c 、溶解時間somin 、溶劑比75 : 30ml / g時,對分離蔥和咔哇混合物中咔哇的效果最好,並且從高溫和低溫下分離后得到固體含量可以看出,在這兩個溫度下過濾得到蔥的含量差不多,因此,本實驗選擇在常溫下過濾。
  3. In the paper quantitative analysis is done by high performance liquid chromatography to crude anthracene and the separated products, and the hplc conditions : inspected wavelengh : 254nm ; flow velocity : lml / g ; the volume ratio of the methanol / water solution : 81 / 19 ; and inspected temperature : room temperature

    本文用高效液相色譜法( hplc )對粗蒽及分離以後的產物進行了定量分析, hplc的分析條件為:檢測波長: 254nm ;甲醇水溶液的體積比81 19 ;流速: 1ml g ;檢測溫度:室溫。
