Abstract

Procedure for the recovery of styrene, of mixtures consisting essentially of styrene, alpha-phenylethanol, polymers of styrene, acetophenone and up to 5% by weight of ethylbenzene, by distillation of said mixtures; characterized in that it comprises using elemental sulfur as a polymerization inhibitor during distillation and maintaining the molar ratio of acetophenone to the sum of acetophenone plus alpha-phenylethanol, in the liquid phase of said distillation, at a level of at least 0.4 .
