摘要:
Substance mixtures comprising (A) vinyl-containing compounds, (B) an active amount of a mixture inhibiting the premature polymerization of the vinyl-containing compounds, comprising (i) at least one N-oxyl compound of a secondary amine which carries no hydrogen atoms on the &agr;-C atoms, and (ii) at least one iron compound, (C) if appropriate nitro compounds, and (D) if appropriate costabilizers, a process for inhibiting the premature polymerization of vinyl-containing compounds (A) and the use of mixture (B), if appropriate as a mixture with nitro compounds (C) and/or costabilizers (D), for inhibiting the premature polymerization of free radical polymerizable compounds and for stabilizing organic materials against the damaging action of free radicals.
摘要:
Mixtures contain(A) vinyl-containing monomers, and(B) an effective amount of a mixture inhibiting the premature polymerization of the vinyl-containing monomers during the purification or distillation and containing(i) from 0.05 to 4.5% by weight, based on the total mixture (B), of at least one N-oxyl compound of a secondary amine which carries no hydrogen atoms on the .alpha.-carbon atoms and(ii)from 99.95 to 95.5% by weight, based on the total mixture (B), of at least one nitro compound,and a mixture (B) is used for inhibiting the premature polymerization of monomers.
摘要:
Process for the preparation of iodopropargyl compounds of the formula (I), in which R is hydrogen, in each case optionally substituted C1-C20-alkyl, C2-C20 alkenyl, C6-C20-aryl or C3-C20-cycloalkyl and n is an integer from 1 to 6, characterized in that propargyl compounds of the formula (II) in which R and n have the above meaning, are reacted with iodine and/or metal iodides in the presence of a base and using chlorine.
摘要:
The compounds of the formula (I) in which R1 represents hydrogen or in each case optionally substituted alkyl, alkenyl, alkynyl or phenyl are highly suitable as microbicides for protecting plants and materials.
摘要:
Specific azole compounds are outstandingly suitable for stabilizing iodine-containing biocides in industrial materials, more particularly in paints based on alkyd resin.
摘要:
The present process serves for the hydrodehalogenation of halogenated meta-cresols of the formula (I) in which the R1 to R4 radicals are each as defined in the description, and is characterized in that halogenated meta-cresols of the formula (I) are contacted with a catalyst which has been prepared by applying one or more salts of palladium and/or platinum and optionally copper salts to an aluminum oxide or titanium oxide support material, together with hydrogen, at temperatures between 100 and 250° C.
摘要:
Fungicidal trisubstituted 1,2,4-triazine-3,5-diones of the formula ##STR1## in which Ar represents optionally substituted aryl,R.sup.1 represents an optionally substituted aliphatic of cycloaliphatic radical andR.sup.2 represents an optionally substituted aliphatic radical.Many of the intermediates therefor where R.sup.2 is hydrogen and/or the 3-O is replaced by 3-S are also new.
