| Abstract: | Based on the characteristic that styrene can form ternary azeotrope with some special organic solvents and water,a new separation process for recovery of styrene in residue tar discharged from the bottom of styrene distillation tower has been developed.The recovery rate of styrene in the tar is nearly 92%;the mass fraction of crude product styrene is 98%. |
