With petroleum ether you do not extract an aqueous phase, petroleum ether and water do not mix.
and what do you think about adding AcoH after the reaction is finished? in some recipes they write about adding ...
Don’t know, haven’t read about it.
that's what extraction is about to transfer from one phase to another. in this case, from the water phase to the nonpolar solvent phase. that's why IPA extraction is not done here because ipa mixes with water and only gives us a dilution of the solution ... is it wrong?
Then you extract the "freebase" from the water phase and you don`t extract the water phase. This was illogical .
IPA was evaporated in the instructions and oil comes out. Oil with water, I think.
Why you use IPA in the instructions @William Dampier ?

Quite, indeed, yes sir.Just a language mishap.
Yes, it may well be, I was or am still a bit confused, but "to extract" has the meaning of to pull something out, to get something out or to take something out. But also in the recipes it is misleading that the aqueous phase is extracted, I unfortunately do not know the exact English term and how it is used.they also use IPA in the original preparation. why I have no idea. most believe it is better to perform nonpolar extraction anyway.
I have a question: is there a difference in power when doing it with p2np and with bmk?
I have one more question, will the cascade absorption consisting of a buffer and two Dreschl washers filled with a 10% alkali solution be able to eliminate the smell emitted during the reaction? everything, of course, connected to the radiator in advance. the diagram is supposed to look something like this. blue hose leading from the cooler to the buffer connected to the nipple. then it goes to a buchner flask in which there is a 10% alkali solution, the side outlet of the flask is connected to a hose which is introduced to the other such flask with the same solution, and finally a hose is mounted which connects to the carbon filter and the fan.

It all seems very cumbersome.
Perhaps it would be simpler a system with a powerful extractor, carbon filter and, if possible, between ozone to purify the outlet air and come out clean without odors.
eliminate the smell emitted during the reaction
my question at what temperature should I distill?
gentlemen, reading all this and doing it myself I got confused ... namely after adding cucl2 after a while two layers are formed for me, why?
I form two layers before adding the alkali. when added, the oil seemed to mix with the top layer.
