add 37% HCL in small portions, heat is generated which causes Chloroform and DCM to
distill over.
once no more distillate comes over add HCL again and heat till we reach the BP of ethanol then
stop.
contents in receiving flask is washed dried and redistilled multiple times. 20% yield of DCM on chloroform.
Chloroform Boiling point: 61.2 °C
DCM Boiling point: 39.6 °C
is there any way to increase yield with this method?
