Hey to all the bees,
I am starting ab tests on the best high BP solvents to use during the thermal re-arrangement of the imine to amine as seen in the ketamine synthesis on rhodiums page (
Zealot's Complete Ketamine Synthesis (https://www.thevespiary.org/rhodium/Rhodium/chemistry/ketamine2.html)
(https://www.thevespiary.org/rhodium/Rhodium/chemistry/ketamine2.html))
I am testing the following solvents since they have been before mentioned on the hive to be viable solvents. I will hope to once and for all prove they are or aren't with qualitative measurements.
The solvents are:
-DimethylSulphoxide (DMSO)
-Ethyl Benzoate
-Undecane
-decalin
-ultrasene <-- this might be excluded because I did this before but it sucked.. and was dangerous...
-kerosene <--same as above
Also any constructive posts will definetly be appreciated. Also if you want me to test a certain high BP solvent for this procedure please msg me and I will attempt it. Thank you all..
I know this is highly unorthodox but if someone could post a certain patent that is.. well sensored by my searches please do.. the patents is:
PL272575
It has too do with the cleaning of ketamine HCl...
Thank you the person deserve a medal that post this info..

Censored?
It might be a little hard to read....
