Abstract

Of seven common aldehydes examined on cyanide‐treated Dowex‐2 columns, vanillin, salicylaldehyde, benzaldehyde and crotonaldehyde were more or less completely adsorbed and were eluted with water to only very small extents; furfural was completely recoverable and formaldehyde and acetaldehyde partially so. There was some indication of polymerization of some of the aldehydes on the column.

Acetone and ethyl methyl ketone were very easily eluted with water from these columns.
