Ladeira Posted July 5, 2012 Share Posted July 5, 2012 Hey guys I'm looking for a nice drawing of a lab device for fractional distillation at low pressure with reflux ratio. I just can't find anywhere a reflux associated to a fractional distillation. I've seen Perkin triangle but I don't know how it gives me reflux ratio. Thank you! Antonio.

studiot Posted July 5, 2012 Share Posted July 5, 2012 Gosh have your tried typing fractional distillation into bigG? There's thousands of images. Link to comment Share on other sites More sharing options...
Ladeira Posted July 5, 2012 Author Share Posted July 5, 2012 Yes I tried! But I could only find it now. I think I can use a cold finger (see how it provokes the condensation of part of the vapor). I mean, the usual fractional distillation (image below) wouldn't give me the reflux ratio I needed. Link to comment Share on other sites More sharing options...
