How do organic chemists remove solvents with high boiling .

How do organic chemists remove solvents with high boiling .

If you are fortunate to want to remove the solvent from something that is non-volatile and not too heat sensitive, the common approach is to use a rotovap to strip off the solvent. The procedure is done at reduced pressure (either water aspirator, ~25 mm Hg, or vacuum pump (< 0.1 mm Hg) and the application of heat (water bath kinds of .

Chloroform as a solvent? | Student Doctor Network

Jun 16, 2009 · However, hexane and ethyl acetate are miscible, whereas ethyl acetate is not significantly soluble in water. So you could consider EtOAc to be polar because it is more polar than hexane (and in the separation, ethyl acetate is used because of its polarity, with higher EtOAc to hexane ratios giving faster elution of more polar compounds), but .

The ideal solvent should boil higher than, say, DCM or ether, but you can use solubility in the low-boiling stuff to point you in the direction of something more appropriate. If DCM seems like it may work, try recrystallizing in 1,2-dichloroethane. If pentane (or hexane or pet ether) looks good, use heptane. Set up.
