Inhibition of polymerization during distillation of monomers.

摘要

Unintentional or premature polymerization of ethylenically unsaturated organic compounds, such as acrylic acid and monomeric acrylates, during distillation is inhibited by means of a phenolic inhibitor and a manganese or cerium alkanoate of a C5 to C19 monocarboxylic acid. Compositions of ethylenically unsaturated organic compounds with phenolic inhibitors and manganese or cerium alkanoates are also described.
