Ladeira Posted July 5, 2012 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 Posted July 5, 2012 Gosh have your tried typing fractional distillation into bigG? There's thousands of images.
Ladeira Posted July 5, 2012 Author 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.
