Hi,
I am making my own anhydrous acetone for a project. I am buying anhydrous magnesium sulfate since it is easier than baking epson salts for hours. About what ratio do I need to put into regular hardware store acetone to dry it?
Any ideas in what to seal it in once it is created and filtered? I know it starts re-absorbing moisture immediately upon hitting air.
Thanks for any help

I have heard in a few places that EFA is light sensitive, especially in solution, and requires an amber bottle for preparation and storage. Others have said this is not true.
The reason given is because the triazolo ring is sensitive to UV light, which will break down the compound over time.
Can anyone shed some light (ha) on this?

A friend of mine obtained a quantity of 99% ethyl-flualprazolam a few days ago and is about to create a PG solution. She sampled a few mg of powder directly off the balance and was quite impressed, or so she said.
She is now wondering about her PG solution. She's been advised by the Source to maintain a 2mg/1ml ratio in a solution of 90% PG and 10% ethanol, but was also told by the Source that the ethanol was not really necessary.
She is by no means a stranger to creating RC solutions from pure powders, and is inclined to agree with the Source that ethanol is not necessary and 100% PG is perfectly fine and, in her opinion, preferable for most powders she has encountered.
Why then, would the Source suggest 10% ethanol in the first place?
Her high school chemistry teacher told her ethyl-flualprazolam dissolves very thoroughly around 60°C as do most benzo powders of such purity, so why ruin a good benzo by bringing ethanol into this?
The same teacher told her 2mg/ml approaches the solubility limit of EFP in PG at room temperature, so exposure to temperatures lower than ~17°C risks crashing. So why is 2mg/ml recommended?
