Using a binary mixture of isoprene and 2-methyl-2-butene as a feed charge, the effects on extractive distillation with propylene carbonate of various operating parameters such as feed and solvent temperatures, location of entry of the hydrocarbon feed and reflux ratio were studied.
Propylene carbonate was tested for its efficient use as an extractive distillation solvent for the separation of dienes from a C5 fraction. As a result, a diene fraction containing no paraffins and only a trace of olefins was obtained. The addition of ethyl carbitol to increase the miscibility of propylene carbonate with hydrocarbons could improve the recovery of the dienes.
