摘要:N2O4被负载在交联聚乙烯吡咯烷酮(pvp)上,形成一种固体,稳定且可回收的亚硝化剂.该试剂在温和的非均相条件下,室温下二氯甲烷中,对二烷基胺的n-亚硝化表现出优异的选择性,相比二芳基胺,芳基烷基胺及三烷基胺更具选择性.同时,在相似的反应条件下,该试剂也能在primary Amides和n-苯甲酰胺存在下,选择性制备n-亚硝基-N-烷基酰胺.此外,该试剂还能实现对三胺的选择性n-亚硝化和脱烷基化再n-亚硝化.

摘要:The invention relates to surfactant combinations which can be thickened by means of electrolyte and are well tolerated by skin and mucous membranes as basis for shampoos, bath gels and shower gels as well as other cosmetic aqueous cleaning fluids for which an increased viscosity is necessary or desirable for application reasons. The individual components of the mixture are easily obtainable at low cost by synthesis. The surfactant combination contains alkyl polyglycoside and carboxymethylated alkanol ethoxylate alone or carboxymethylated alkanol ethoxylate and monoalkyl sulphosuccinate where appropriate with the addition of a small amount of other surfactant additives, the individual components in the mixture being in a narrow ratio of relative amounts and a highly synergistic increase in viscosity being achieved.
