The Batch Distillation Separation of 2,4-DimethyI Nitrohenzene and 2,6-DimethyI Nitrobenzene

Zhang Xiucheng et al.(Departrment of Chemical Engineering,Northwest University,XiAn,710069)  
The nitrated m-xylene were separated by abatch distillation in a packed columm with a 20 mm inside di-ameter and 1200 mm height.the influences of reflux ratio andthe temperature on the concentration of the column top werediscussed.The experiment results indicated that the about98%object products of 2-and 4-nitro-m-xylene were obtainedrespectively from the columm top and the still pot when thepresure of the column top is about 0.002 MPa.
