INHIBITION OF POLYMERIZATION FOULING DURING DISTILLATION OF MONOMERS IN THE PRESENCE OF SULFUR OXIDES

摘要

Polymer formation is inhibited during the distillation of ethyl acrylate and acrylic acid produced from the reaction of ethylene and acrylic acid with sulfuric acid. In the presence of sulfur dioxide formed during the reaction, nitrogen oxide (NO) is highly effective for inhibition of polymerization fouling.
