ABSTRACT:
Polymer formation and aldol condensation by a hydrocarbyl aldehyde is prevented by adding to the aldehyde a trace to minor amount of readily oxidizable metals or cations having oxidation potentials greater than about -0.2 volts. In a typical embodiment, a liquid containing a hydrocarbyl aldehyde is inhibited against aldol condensation by incorporating in the liquid from about 0.005 to about 1.0 weight percent thereof of the aforementioned metals or cations.
