Help needed please !
Hi the pseudo pills that i have are made up from 50% pseudo and the rest is SACCHAROSE and MODIFIED CORN STARCH. My Question is what is the best way to get rid off the SACCHAROSE and MODIFIED CORN STARCH would these 2 dissolve in Toluene in the pre wash or would i need to use something else. Thanks for your help.

No first you make it basic with NaOH then you extract (or wash) it with toluene. The sugar stays with the water and the E freebase goes into the toluene. You can evap off the toluene and use the freebase E or you can dry the toluene over anhydrous MgSO4 and gass with anhydrous HCl to get Ephedrine HCl salt.
