Kash said:I respectfully disagree 100%. While water is an issue with acetone, in all experimentation it is negligible with MEK, and gives the cleanest, driest product. Acetone works, but it WILL soak up product if you dont make it anhydrous, and tends to leave things more sticky even after.
Isn't MEK partially miscible with water? If you get lab-grade pure MEK, then it should be OK, but what if it is not as good? Then drying with MgSO4 is likely a good idea.
