| titleOfInvention | Oxystyrene derivative distillation method |
| abstract | (57) [Summary] (Modified) [Problem] High quality by suppressing decomposition and coloring of oxystyrene derivatives and polymerization inhibitors without impairing the polymerization inhibitory effect of nitroso compounds and nitro compounds as polymerization inhibitors. A highly economical distillation method for obtaining oxystyrene derivatives such as P-tert-butoxystyrene (PTBS), P-acetoxystyrene (PACS) and m-tert-butoxystyrene (MTBS) at a high recovery rate. A method of distilling an oxystyrene derivative in the presence of a nitroso compound and / or a nitro compound in the presence of an epoxy compound when the oxystyrene derivative of the general formula 1 is distilled. Further, a distillation method, wherein the nitroso compound is N-nitrosophenylhydroxylamine and / or a salt thereof, and the nitro compound is dinitrophenol. (R is an alkyl group, an aryl group, an arylalkyl group, Represents an alkoxyalkyl group, an alkylcarbonyl group, an alkoxycarbonyl group or an alkylsilyl group) |
