My friends solvent is freezing! Anyone else experienced this? There are icy chunks floating around the "soup". Is his freezer to strong? (-30°C)
There'S no water contamination.

freezer cant be too strong. whats your solvent? and what is the color of your solution?
My friends solvent is medical grade petroleumether. It's usually colorless...but maybe my friend just got huge chunks of xrystal this time? That would be wicked.
remember petroleum ether is not really an ether in the chemical sense. ether being an oxygen atom between two or more carbons. petroleum ether is really light distallites of petroluem (they called it ether back in the day because it was this magical stuff that came from heating crude petroleum) and the light distillates are things like hexane heptane could even be octane pentane etc (the composition probaly varies a bit depending on who made it and how it was purified). so when you have a petroluem ether it is a mix of hexane and other smaller straight chain hydrocarbons, in other words its a good solvent to work with because it evaps easier and has many of the properties as other straight chain hydrocarbon solvents its just a mix of them.
He's put the container in the fridge to let the ice melt...but it didn't. So it seems like he's got big white chunks of crystal after recrystallisation!
The previous times he encountered ice , it propably was due to remaining water after cleaning the container.
thanks burnt for the lecture about my solvent. Always wanted to know if it's suitable or not.

Hey that's great. I hope your friend enjoys the fruits of his labor.
