Distillation of vinylaromatic monomer, especially styrene, is carried out in presence of 4-tert.-butylcatechol and oxygen without adding aromatic nitro- or amino-compound

In the distillation of vinylaromatic monomers (I) in the presence of 4-tert.-butylcatechol (II) and oxygen (O2), no aromatic nitro- or amino-compound is added in effective amounts. Ein Verfahren zur Destillation von vinylaromatischen Monomeren in Gegenwart von 4-tert.-Butylcatechol (TBC) und Sauerst...

description	In the distillation of vinylaromatic monomers (I) in the presence of 4-tert.-butylcatechol (II) and oxygen (O2), no aromatic nitro- or amino-compound is added in effective amounts. Ein Verfahren zur Destillation von vinylaromatischen Monomeren in Gegenwart von 4-tert.-Butylcatechol (TBC) und Sauerstoff, wobei keine aromatische Nitro- oder Aminverbindung in wirksamen Mengen zugegen ist. Das Verfahren eignet sich insbesondere zur Entstabilisierung und Reinigung von zum Transport mit 4-tert.-Butylcatechol (TBC) stabilisiertem Styrol.
