Thank´s a lot Shake for the info(..and there is no second sense behind that ).
If you have read some post from me,you can see i´m a guy that one day "wow...that method rules...." and weeks after cooment about the same..."that method sucks"...
Posibly i´m not too constant about chemistry theory....and prefer allways to follow practical experiences insted theoricall explanations,but of course can be an error of mine,but i´m used to believe only on things that i or othesr have seen directly instead of hypothesis,theoricall fundaments about a reaction....but i repeat it´s my fault.
For example,i was extracting my last benzo wackers since moths ago with toluene,after i got freaking emulsions using DCM to extract both from DMF and Methanol on my begining.Now,i consider me a lot more formed about that process and others(a lot),and since last times i extracted with toluene and get a lot of tar on the ketone distillation every time,and last time got a very clean distillation after use DCM,....we can think it´s related about less benzoquinone used....but i have made exactly the same batch using toluene and DCM,and without doubt the extractions and distillation were way more clean and easy,and since that,yields were higher.Explanation?i don´t have it yet.But like said,i think i mastered the benzo at this moment,and to me the best,will be go with DMF and DCM.
I can talk about how pure it´s the ketone,but like said,i think very pure.Like i use now to redistill the ketone,i don´t worry too much if first ketone distilled it´s not too much pure.
Anyway,i will reduce some of that ketone these days,so posibly amine yields can talk about it.
I´m planning too since now i have a strong vacuum,distill first the amine base before gassing to get product as pure as posible.
I´m plannin too on go a little into the old scholl gassing methods, since both DCM and Toluene are not cheap and easy to get to me,and try to gas into dry cold acetone like old bees i´ve read used to do.But of course it´s a question i will treat on the "SHORT QUESTIONS THREAD"
THANK¨S MAN!
