Separation of 4-methyl-2-pentanone from formic acid by extractive distillation with DMSO |
摘要 |
4-Methyl-2-pentanone cannot be easily separated from formic acid by distillation because of the closeness of their boiling points. 4-Methyl-2-pentanone can be readily removed from formic acid by extractive distillation. Typical effective agents are dimethylsulfoxide (DMSO) and 2-undecanone; DMSO and octanoic acid; DMSO and hexyl acetate.
