Teacher, toluene is a non-polar solvent. Does that mean that after toluene is extracted, dried and filtered, hydrogen chloride can be directly introduced
Teacher, what I don't understand is that if I use toluene for extraction and sodium sulfate for dry distillation, will toluene be distilled together with amphetamine
Teacher, this is how I operate. Can you help me take a look! After heating and refluxing, I extracted it with toluene and poured it into anhydrous sodium sulfate to dry it. After filtration, I distilled the toluene and left behind amphetamine before introducing hydrogen chloride
Teacher, is it feasible to replace DCM with toluene without DCM? Is it correct to distill toluene after drying, leaving behind a yellow liquid instead of distilling it all together
May I ask if the reason why there is no white sediment when introducing hydrogen chloride is because the extract is not dry? Or are there any other reasons that could have caused it
All the previous programs have been completed, but every time hydrogen chloride is introduced, there is no sediment produced, and toluene is also dried with anhydrous sodium sulfate. What is the reason
Is there any question about the distillation of anhydrous sodium sulfate after drying in Figure 16? After DCM distillation, amphetamine will be separated from DCM
