Hey, I'm thinking about doing this optional step and I've got a few questions.

- Will a vacuum pump like that work for both distillation and vacuum drying?

- Is it worth paying extra for this one instead? Will it actually make a noticeable difference in the procedure?

- Is using a separatory funnel way easier or more efficient than mixing the mixture in a beaker with a stirrer? I’m asking because ventilation here isn’t great so I wanna pick a method that produces fewer harmful fumes. [step 3]

- I assume that a magnetic stirrer would struggle with this amount of liquid and it’s better to use an overhead stirrer, right? Do you know any reasonably priced models that you can recommend?

- What exact reduced pressure values are we talking about? [step 4]

- Does the freezer temperature matter? Would setting it to -22°C instead of -18°C be beneficial in any way? [step 6]

Hello, the first one is more than enough.

>- Is using a separatory funnel way easier or more efficient than mixing the mixture in a beaker with a stirrer? I’m asking because ventilation here isn’t great so I wanna pick a method that produces fewer harmful fumes. [step 3]

What?? It's clearly said that you need separatory funnel. It's more convenient for handling.

>- I assume that a magnetic stirrer would struggle with this amount of liquid and it’s better to use an overhead stirrer, right? Do you know any reasonably priced models that you can recommend?
Anyone, you can even use even a screwdriver for this.

>- What exact reduced pressure values are we talking about? [step 4]
I can't say for sure, you need to increase vacuum and temperature slowly until it will start to boil.

>- Does the freezer temperature matter? Would setting it to -22°C instead of -18°C be beneficial in any way? [step 6]
I don't think that it is valuable

@G.Patton Sorry, I think I misunderstood the instructions. English is not my first language. It seemed to me that in this step you were writing as if the use of a separatory funnel wasn’t necessary, and that if it is used, it requires frequent venting.

- Is it possible to replace DCM with something else without a noticeable loss in quality? I’m concerned about the ventilation issue, hence the question.

- How does the second extraction method affect product quality? I mean the yield, potency, and duration of action.

Thank you

How it is with solubility of potassium carbonate in DMF?
Would be a caesium carbonate better option?

The solubility of potassium carbonate in DMF is approximately 7.5g/L at ambient temperature
CaCO3 isn't soluble and not suitable for this due to its less basic properties.
