如何除掉甘油 ??? 20分`

如果分二層的話 , 最容易是用separated funnel , 將此mixture倒入funnel內去 , 攪一會再等30minutes後 , 讓油與水溶glycerine分離為二層後 , 由funnel慢慢將低層的油放出來 , 及就到生物燃油與甘油merge層就stop . This is the easy way but you need to have a separated funnel .

Sorry I just reverse the suitation . You should have the oil on top & glycerine on bottom so you let the glycerine flow out first in one receiver & than use a other bottle to get the oil .
