发明名称 Separation of heptane from 1-heptene by extractive distillation
摘要 Heptane is difficult to separate from 1-heptene by conventional distillation or rectification because of the proximity of their boiling points. Heptane can be readily separated from 1-heptene by extractive distillation. Effective agents are diacetone alcohol, ethyl butyrate and dimethylsulfoxide.
