Abstract (en)
[origin: DE19725519A1] The invention relates to a mixture of substances containing one or several compounds with vinyl groups as constituent (A) and a stabilizer (B) as another constituent containing one or several easily volatile nitroxyl compounds as constituent (b1), one or several non-easily volatile nitroxyl compounds as constituent (b2), optionally one or several aromatic nitro compounds as constituent (b3) and optionally one or several iron compounds as constituent (b4). The invention also relates to stabilizers (B) containing constituents (b1) and (b2), (b1) and (b2) and (b3), (b1) and (b2) and (b4), in addition to (b1), (b2), (b3) and (b4). The invention further relates to a method for inhibiting premature polymerization of compounds with vinyl groups during the cleaning thereof or distillation by adding a stabilizer (B), or by adding the constituents of stabilizer (B) as individual substances or in at least two groups of constituents.
