The rxn is left for 1 day and the solvents are removed under aspirator vacuum


my question ishow to removed the solvent ,the equipment and how to use the equiptment,the degree and the pressure.

some steps about ketamine synthesis

[wslwh2005]

45g of the above bromoketone is dissolved in 50mls benzene, add therein 50mls ?:namespace prefix = st1 ns = "urnchemas-microsoft-comfficemarttags" /><st1:chmetcnv wt="on" UnitName="g" SourceValue="17" HasSpace="False" Negative="False" Number="1" TCSC="0">17g</st1:chmetcnv>(=23mls) is required for neutralization of HBr, but a 2x excess is used). The soln is then saturated with <st1:chmetcnv wt="on" UnitName="g" SourceValue="5" HasSpace="False" Negative="False" Number="1" TCSC="0">5g</st1:chmetcnv> methylamine, obtained by dripping a saturated soln of <st1:chmetcnv wt="on" UnitName="g" SourceValue="15" HasSpace="False" Negative="False" Number="1" TCSC="0">15g</st1:chmetcnv> MeNH2*HCl onto <st1:chmetcnv wt="on" UnitName="g" SourceValue="10" HasSpace="False" Negative="False" Number="1" TCSC="0">10g</st1:chmetcnv> NaOH, dried thru NaOH. The rxn is left for 1 day and the solvents are removed under aspirator vacuum, giving <st1:chmetcnv wt="on" UnitName="g" SourceValue="30" HasSpace="False" Negative="False" Number="1" TCSC="0">30g</st1:chmetcnv> (80%) of methylketimine.


anybody can tell me the steps (red line) in detail,use what equiptment and how use the equipments.

Equipment: Vacuum aspirator, Vacuum Tubing, Flask w/ one hole stopper


put rxn in flask for one day then connect the aspritor , tubing and flask. turn on vacuum until solvent is removed


Are you sure u want to do this???????? because you haven't the faintest idea of the most basic of basics......................... please don't kill anybody

If you don't understand such things as "rotary evaporator" or "Soxhlet Extractor" and have a working knowledge of how these - and all the rest of the apparatus found in an organic chemistry lab - work with your eyes closed and both hands tied behind your back, you have no business playing with these chemicals/equiptment.


If you persist, I certainly hope your "laboratory" is far removed from anyone elses' home and that you have 911 on speed-dial on your cell phone.

Is your friendmaking Ketamine?

[ChemicallyBound]

Yes he is trying to make ketamine I believe.


He is also a china guy somewhere in the middle of china, doesn't have a clue.................................
