Hello I was wondering about whether or not to use an amonia wash after the crystals have been frozen. I have previously freezed the slovent, poured off naptha and let the crystals dry in pan then scrape up and put to use.( This seems to work fine as it has provided an effective product) I am a bit paranoid though and dont want to smoke any lye or other impurities is it nessecary to further purify?? Thanks for the help!
Even [i:f45080df73]if[/i:f45080df73] you'd mechanically caught some up in there, there's no risk you'd be vaping it.Never done an ammonia wash, but I do tend to wash all my solvent fractions with sodium carbonate solution.Check your solvent half an hour after putting in freezer; if you've caught any basic layer in there it'll be freezing up and red at the bottom then.If so, you know to give it a wash,; saying that though, as it can't harm you it's more for aesthetic/perfectionist reasons than anything else.
