Comparing Catalytic Distillation to Separate Reaction and ...
Sep 01, 2003· The reaction is severely equilibrium-limited and high conversions of acetone are only possible if the unconverted acetone is separated and recycled. The reaction, separation and recycle can either be done separately in a reactor-distillation column-recycle process (RDR) or simultaneously in a catalytic distillation (CD) column.

THE SEPARATION OF ACETONE-METHANOL MIXTURE BY …
Apr 03, 2007· Abstract Acetone and methanol can not be readily separated by ordinary distillation because of the presence of the minimum boiling azeotrope. Either acetone or methanol can be the overhead product when an appropriate agent is applied in extractive distillation. An unusual phenomenon, "temperature inversion", was observed when ketones were used as the extractive distillation agents.

Nov 09, 2005· I'm working on an idea that involves the use of an acetone/water binary mixture as a working substance. Here is some background: The working substance (acetone/water - low H2O concentration <5%) picks up water in a subsequent step, and is redirected to a distillation step where the water is stripped back out.
