Polymerization inhibitor for vinyl aromatic compounds |
摘要 |
A process for the distillation of readily polymerizable vinyl aromatic compounds which comprises subjecting said compounds to distillation conditions in the presence of an effective amount of a pretreated polymerization inhibitor selected from the group consisting of asphalts, asphaltenes and any combination thereof. The inhibitor is pretreated by subjecting the inhibitor to a process for substantially increasing the free radical content therein.
