PROCESS FOR PURIFYING VINYLAROMATIC NONOMER
A process for purifying a vinylaromatic monomer, which contains a phenolic polymerization inhibitor, by passing it over a fixed bed of alumina particles, characterized in that the particle size ranges from 0.5 to 3 mm, the monomer space velocity ranges from 0.5 to 7.5 h, and the monomer linear veloc...

| Zusammenfassung: | A process for purifying a vinylaromatic monomer, which contains a phenolic polymerization inhibitor, by passing it over a fixed bed of alumina particles, characterized in that the particle size ranges from 0.5 to 3 mm, the monomer space velocity ranges from 0.5 to 7.5 h, and the monomer linear velocity is in the range from 0.125 to 45 m/h. |
