Abstract RU 2043325 C1

FIELD: petrochemical industry. SUBSTANCE: fraction enriched with styrene (concentration is 60-80%) is isolated from methylphenylcarbinol dehydration product at rectification by side selection from methylphenylcarbinol products. Highly volatile and heavy-boiling impurities (with regard to styrene) were recirculated further to the first stage of separation. EFFECT: improved method of styrene isolation. 1 dwg, 4 tbl
