Abstract: The use of amidoximes for stabilisation of ethylenically-unsaturated compounds against undesired radical polymerisation is disclosed. Combinations of amidoximes with phenol and/or phenothiazine compounds have a synergistic effect. Preferred amidoximes are nitrilotris(acetamidoxime) and nitrilotris(propionamidoxime).

Abstract: A description is given of an absorption medium for deacidifying fluid streams which has improved oxidation stability and comprises at least one aliphatic amine, in particular an alkanolamine, and at least one non-hydroquinoid antioxidant. The absorption medium serves for deacidifying a fluid stream, in particular an oxygen-containing fluid stream, the fluid stream being brought into intimate contact with the absorption medium in at least one absorption step.

Abstract: A stabilizer mixture (I) comprises at least one radical trap containing at least two glycerol units with the proviso that it is not ethylenediamine tetraacetic acid (EDTA), diethylenetriamine pentaacetic acid (DTPA), trans-1,2-cyclohexane diamine tetraacetic acid (CYDTA) or their alkali or alkaline earth salts, and at least one other stabilizer or costabilizer. Independent claims are included for: (1) a mixture (II) comprising a stabilizer mixture (I) and at least one polymerizable compound; and (2) a process for the stabilization of polymerizable compounds during processing, storage and/or transport by use of the radical trap.
