Apr 29, 2012 · Unfortunately you need good organic solvents for this, and a vacuum line/rotovap to ensure you remove all the nasty solvent. With what you can get, easily fasteddie's method is fairly sound as long as methHCl is insoluble in acetone and soluble in methanol (and honestly, i really don't know because i don't play around with meth)

May 24, 2017 · Part of the experiment involved an extraction using a cooled Rotovap extraction. This particular extraction needed a very cold trap. We were using dry ice in an acetone bath (-78℃/-108℉). As I was putting in a block of dry ice into the acetone, the warm (relatively speak) acetone flash sublimated the dry ice.

Aug 09, 2013 · Once you reassemble the rotovap, just evaporate some methanol, acetone, DCM and a few other solvents to clean the organic side of the condenser. You normally don't worry about the distilled solvents being absolutely clean, unless you are trying to recover them, and even then I would re-distill them with a normal still anyway if you want to get .

Rotary evaporator - Wikipedia

Rotary evaporator - Wikipedia

A rotary evaporator (or rotavap /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was .

I read a PDF about a DIY rotary evaporator and i sure would want a rotovap but building a DIY one is quite a project and one need a good lathe and other tools. A new or even a used one is out of my budget right now. But what caught my interest was in the paper there was a comparison of evaporation rates of acetone.
