Process for obtaining pure aliphatic aldehydes |
摘要 |
Pure aliphatic aldehydes can be obtained from the corresponding crude aldehydes which contain organic chlorine compounds, by extracting the aldehyde from the crude aldehyde by means of a polar solvent and treating the extract with an unpolar countersolvent. The process is particularly effective when the extraction is preceded by a distillation.
