    Abstract: The invention relates to a mixture of substances including one or more compounds with vinyl groups as component (A), and as component (B) - stabilizer containing one or more easily volatile nitroxyl compounds as component (b1), one or more not easily volatile nitroxyl compounds as component (b2), optionally one or more aromatic nitrocompounds as component (b3), optionally one or more iron compounds as component (b4). The invention also relates to stabilizers (B) containing the components (b1) & (b2), (b1), (b2) and (b3), (b1) (B2), (b4) and (b1),(b2), (b3) and (b4), and to a method for the inhibition of the premature polymerization of compounds containing vinyl groups during their refining or distillation by the addition of either stabilizer (B) or components from it as individual substances or at least as two groups of components. 10 claims

    Abstract: A mixture contains one or more vinyl-containing compounds as component (A) and, as a further component, a stabilizer (B) which contains one or more readily volatile nitroxyl compounds as component (b1), one or more sparingly volatile nitroxyl compounds as component (b2), if required one or more aromatic nitro compounds as component (b3) and, if required, one or more iron compounds as component (b4).Stabilizers (B) contain the components (b1) and (b2), (b1) and (b2) and (b3), (b1) and (b2) and (b4), and (b1), (b2), (b3) and (b4), and the premature polymerization of vinyl-containing compounds during their purification or distillation is inhibited by a process in which a stabilizer (B) is added or the components of stabilizer (B) are added as individual substances or in at least two groups of the components.

    Abstract: 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.
