Question:Right you have your 'raw' opium out the poppy, now how do you separate the codeine/morphine other alkaloids? What acids etc to use and the method, also how do you get the phosphate to attach to the codeine? (After its been separated?) If anyone has a link to a method or can tell is, be great thanks! (A know the dangers of these chemicals..etc! This is a pure chemistry question! Thanks!

Answers:Various methods are outlined here:- Isolation of Morphine and Heroin Production: 1. The Thiboumery and Mohr Process 2. The Robertson and Gregory Process (RGP) 3. The Barbier Purification 4. The Schwyzer Purification 5. The Heumann Purification 6. The Merck process http://drugs-abuse.blogspot.com/2007/05/isolation-of-morphine-and-heroin.html http://www.wikishaman.org/wiki/index.php?title=Opium http://www.unodc.org/unodc/en/data-and-analysis/bulletin/bulletin_1950-01-01_3_page004.html http://www.ch.ic.ac.uk/rzepa/mim/drugs/html/morphine.htm http://pubs.acs.org/doi/abs/10.1021/ac60191a034

Question:I want to separate the dissolved citric acid from a mixture of water and isopropanol without driving off the liquids. How do I do this? Thank you so much!!!

Answers:You could probably achieve what you want using column chromatography on silica gel (SiO2) or alumina (Al2O3)? Success would depend on the ratio of water to isopropanol and the concentration of citric acid in your mixture. See: http://www.ashirwadchemicals.net/chromatography-grade-silica-gel.htm http://orgchem.colorado.edu/hndbksupport/colchrom/colchrom.html http://orgchem.colorado.edu/hndbksupport/colchrom/colchromprocgravity.html

Question:I am completely lost on this assignment and need a sort of push in the right direction. For my lab class I will have to separate the compounds from a soil sample; there are about three or four compounds that will be present (out of CuCl2, CoSO4, NiCl2, biphenyl, benzoic acid, camphor, m-nitroaniline, and naphthalene). Do you have any ideas as to how one might separate the compounds and/or test for their presence after separation? They don't have to be very specific to this experiment, but I need some ideas to work with. Thank you in advance! mrfarabaugh - thanks for your response. I've used that technique for other experiments, but only when there was one compound to isolate. How could you separate the multiple compounds from one another after separating the inorganic and organic?

Answers:You can do qualitative analysis on the inorganic compounds. The Cu, Co, and Ni ions can be identified (by color) and precipitated out of the solutions one by one with the right reagents. How about column chromatography for separating the organic compounds?
