| Abstract: | In this paper,taking the separat ion of m-diethenyl-benzene and p-die thenyl-benzene from C10heavy Aromatics as background for study.The o-dimethyl-phthatate was selected as the solvent for the separation of diethenyl-benzene preconcentrated from C10heavy Aromatics,by extractive ditillation,and the effect of the solvent was investigated by continuous distillation experiment. |
