Abstract
1522913 Inhibiting polymerization of vinyl aromatic compounds COSDEN TECHNOLOGY Inc 17 Feb 1977 [19 Feb 1976] 06729/77 Heading C5E The polymerization of vinyl aromatic compounds is inhibited during distillation in the presence of oxygen by the presence of a combination of phenothiazine and a phenolic compound. The inhibitor system may comprise 5-200 p.p.m. phenothiazine and 1-100 p.p.m. tert-butylcatechol. Nitroso diphenylamine may also be present in an amount of 10-500 p.p.m. Examples describe the distillation of styrene.
