| titleOfInvention | Oxystyrene derivative distillation method |
| abstract | PROBLEM TO BE SOLVED: To provide a novel oxystyrene derivative distillation method which does not show the drawbacks of the conventional method. The compound represented by the following general formula (II) is used as a polymerization inhibitor. (Wherein R is an alkyl group, a haloalkyl group, an aryl group, especially a phenyl group, an aralkyl group, especially a benzyl group, An alkoxyalkyl group, an alkanoyl group, an alkoxycarbonyl group, an aralkyloxycarbonyl group, or an alkylsilyl group), and distilling the oxystyrene derivative in the presence of the added compound. A method for distilling the oxystyrene derivative, characterized by the following, has been developed. According to this method, the formation of a highly viscous polymeric substance during the distillation step was sufficiently prevented, and the effect of obtaining a high recovery of the distilled oxystyrene derivative was obtained. |
