    The oxidation of aliphatic aldehydes to the corresponding carboxylic acids by sodium N-bromoarylsulphonamides (N-bromoamines) is first order with respect to the oxidant, the aldehyde and hydrogen ions. In the oxidation of acetaldehyde at 298 K, the primary kinetic isotope effect, kHkD is 4.91 ± 0.14 and the solvent isotope effect, k(H2O)k(D2O), is 0.43. Addition of the parent sulphonamide does not
    关于氧化剂,醛和氢离子,通过N-芳基磺酰胺(N-胺)将脂族醛氧化为相应的羧酸是一级的。在298 K乙醛氧化中,主要的动力学同位素效应kHkD为4.91±0.14,溶剂同位素效应k(H2O)k(D2O)为0.43。母体磺酰胺的添加不影响该速率。六个取代的N-胺的还原反应在298 K下的反应常数为1.22。(ArSO 2 NH 2 Br)+被假定为反应性氧化物质。已经计算出合醛和游离醛形式的氧化的独立速率常数。醛合物的氧化速率与具有负反应常数的塔夫脱取代基常数很好地相关。提出了涉及从醛合物到氧化剂的氢化物转移的机理。

    According to the invention there are obtained modified polyurethanes which have a durable, wash-fast, acid-resistant, cleaning-resistant and solvent-resistant stabilization on the basis of 2,2,6,6-tetraalkyl-piperidine light protective agents. The stabilizers are integral constituents of the polyurethanes, that is to say they are built into the polyurethane chain by a chain lengthening reaction in which two H-active reactive groups (preferably from the series of primary or secondary amino groups, carboxylic acid hydrazide, carbazic ester or semicarbazide groups) of a 2,2,6,6-tetraalkyl piperidine derivative react with isocyanate groups of polyisocyanates or isocyanate prepolymers, optionally in the presence of the usual chain lengthening agents.
