Abstract: The invention concerns substance mixtures containing: (A) compounds containing vinyl groups; (B) an active amount of a mixture which inhibits premature polymerization of the compounds containing vinyl groups and contains: (i) at least one N-oxyl compound of a secondary amine which does not carry any hydrogen atoms on the .alpha.-carbon atoms; and (ii) at least one iron compound; (C) optionally nitro compounds; and (D) optionally co-stabilizers. The invention further concerns a process for inhibiting the premature polymerization of compounds (A) containing vinyl groups, and the use of mixture (B), optionally mixed with nitro compounds (C) and/or co-stabilizers (D), for inhibiting the premature polymerization of radically polymerizable compounds and for stabilizing organic materials against the harmful effect of radicals.

Abstract: Mixtures of substances, comprising (A) vinyl monomers and (B) a mixture designed to inhibit premature polymerisation of (A) during purification or distillation, containing (i) 0.05-4.5 wt.% sec. amine N-oxide compound(s) with no hydrogens on the alpha -carbon atoms, and (ii) 99.95-95.5 wt.% nitro compound(s). Also claimed is a method for inhibiting premature polymerisation of monomers (A) by adding mixture (B) or its components before or during purification or distillation.

Abstract: The present invention relates to a method for purifying olefin-containing supply flows in polymerisation or alkylation processes, wherein said method involves feeding the supply flow through an adsorption layer. The invention also relates to methods for producing alkylbenzenes by the catalytic reaction of benzene and olefins fed through an adsorption layer.

Abstract: Process for distn. of styrene in at least one distn. column in the presence of a nitrophenol (I) as polymerisation inhibitor, whereby the (I) is introduced into the feed stream to the column and accumulates in the residue at the base of the column, from where it is recovered in the form of a phenolate by reacting the residue with ammonia, and the (I) is then introduced into the feed stream to the column in the form of the ammonium phenolate.
