solvent ratio meaning in Chinese

溶剂比

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 、溶解时间60min 、溶剂比125 : 5oml / g ，对分离粗葱中菲的效果最好，可以使粗葱中菲的含量从10 . 3 %提到41 . 7 % 。 dmf在120 ’ c 、溶解时间somin 、溶剂比75 : 30ml / g时，对分离葱和咔哇混合物中咔哇的效果最好，并且从高温和低温下分离后得到固体含量可以看出，在这两个温度下过滤得到葱的含量差不多，因此，本实验选择在常温下过滤。
