Hello, I'm a newbie and I'm still trying to learn chemistry. My English is not good, I use Google Translate, please understand。
Regarding your "Second (simplified) extraction way to Ephedrine free base", I have some questions to ask。
Question 1。 How many grams of ephedra powder should be used in 1st step and 2nd step?
Question 2。1st step: "b) After 15 minutes filter the mush through a #15 gold filter with a coffee filter inside the gold filter (you can use a laboratory glass funnel or another filter sieve) then set the mush aside.". Does "the mush" still work after that? Can I discard "the mush" from this step after I'm done with it? What should I do with "the mush"?
Question 3。2nd step: "a) Same as before, placed it in a four quart Pyrex pot. To the pot add 750 mL Naphtha, shake it vigorously 5-10 min and let it soak for three days.""placed it in a four quart Pyrex pot". What does "it" primarily refer to? Is it the white powder after the first step? Or the paste from step b in step one? Or the new ephedra powder?
Sorry, because my English is not good, so some questions may be difficult for you to understand. Looking forward to your reply, thanks!
