| Abstract: | The application of extractive distillation and reactive extrative distillation in the reco very of tetrahydrofuran (THF) has been studied. The extractants and reactive extractants were selected, the process flow and optimum operation conditions were determined in the study. The results show that the purity (as mass fraction) of THF recovered from waste pharmaceutical liquor can reach 99.4%. |
