Distilling DCM for reuse?

If one were to use DCM to defatt some plant material in a sohxlet, would he just distill as normal or would he have to do something like steam distill so as to leave the fats suspended on the water.
 
Would that mean that one should use dual condensors? Or should a bath of isopropyl alcohol and dried ice be cold enough for a single condensor.
 
SWIM does this all the time. Just make sure you have plenty of cooling area. A long condenser or even 2 is good. The receiving flask should have a 24/40 top and be connected to the condenser with a small 24/40 claisen connecting adapter between the two. The claisen adapter has 3 24/40 connectors, 2 at the top, and one at the bottom. The bottom one is connected to the receiving flask, one of the top ones is connected to the condenser coming from the still, the other 24/40 top should be connected to a 24/40 hose inlet adaptor. The hose inlet adaptor allows a small amount of air to pass through but helps keep the DCM from evaporating away. If you have two condensers, then place the second condenser (it can be a really small one) on the other 24/40 top of the claisen adapter between the hose inlet adaptor and the claisen adapter. This will work very well to prevent any loss of DCM out of the hose inlet. With that type of two condenser system, you can expect to recover about 99% of the distilled DCM.
 
When using DCM to extract from a basified H2O solution, could the DMT-laden DCM be distilled off mostly, except for a very small amount to be later evaporated? DCM's BP is 40.. is that too high for freebase DMT?
 
That's how SWIM does it, well sort of. He distills off the DCM and then right before all of it's gone, he adds cold acetone and then distills off the rest of the DCM until the acetone starts to distill. Then he evaporates the acetone. It works VERY WELL. Although I think it might cause some DMT-Oxide to form. When SWIM extracts from chacruna he gets fantastic yeilds, so I don't think any is getting lost from the distillation of the DCM or the acetone.
