Recovery of 4-methyl-2-pentanone from acetic acid by distillation |
摘要 |
When 4-methyl-2-pentanone and acetic acid mixtures are subjected to extractive distillation with a dimethyl sulfoxide - pelargonic acid mixture as the agent, the acetic acid is converted to gaseous ketene which is easily recovered from the 4-methyl-2-pentanone.
