  The invention relates to nanoparticles made from organometallic hybrid materials made from iron carboxylates, used for example as contrast agents. The particles can also be used for the encapsulation and vectoring of molecules of interest such as active3 pharmaceutical agents, cosmetically interesting compounds and markers. Apart from the intrinsic properties thereof for imaging, said nanoparticles give good results in terms of capacity for loading with medicaments and in biocompatibility.

• Inhibition of pulp and paper yellowing using hydroxylamines and other coadditives

  公开（公告）日：2002-11-28

  Pulps or papers, especially chemimechanical or thermomechanical pulps or papers, which still contain lignin, have enhanced resistance to yellowing when they contain an effective stabilizing amount of a N,N-dialkylhydroxylamine, an ester, amide or thio item substituted N,N-dialkylhydroxylamine or N,N-dibenzylhydroxylamine or an amminium salt thereof. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective. N,N-Diethylhydroxylamine and N,N-dibenzylhydroxylamine and their acid salts are surprisingly effective for this purpose.

  含有木质素的纸浆或纸张，尤其是化学机械或热机械纸浆或纸张，如果它们含有有效稳定剂量的N,N-二烷基羟胺、酯、酰胺或硫代物取代的N,N-二烷基羟胺或N,N-二苄基羟胺或其铵盐，它们具有增强的抗黄变性能。当它们与紫外线吸收剂、聚合抑制剂、亚硝基化合物、荧光增白剂和金属螯合剂等共添加剂之一或多个存在时，这种性能通常会进一步增强。N,N-二乙基羟胺和N,N-二苄基羟胺及其酸盐对此具有惊人的有效性。羟胺或其盐、苯并三唑或苯并酚紫外线吸收剂和金属螯合剂的组合特别有效。
• Chlorohydrin and cationic compounds having high affinity for pulp or paper

  Selected chlorohydrin and cationic compounds containing nitroxide or hydroxylamine moieties are effective in stabilizing pulp or paper, especially pulp or paper containing lignin, against yellowing and discoloration due to the adverse effects of light. These compounds are added at various points in the paper-making process, especially at the wet ends, making the need for water soluble or water dispersible materials having high affinity for pulp or paper essential. This performance is often further enhanced by the presence of one or more coadditives selected from the group consisting of the UV absorbers, the polymeric inhibitors, the nitrones, the fluorescent whitening agents and metal chelating agents. Combinations of hydroxylamines or their salts, benzotriazole or benzophenone UV absorbers and a metal chelating agent are particularly effective.

  选择的含氮氧自由基或羟胺基团的氯水合物和阳离子化合物对于稳定纸浆或纸张，特别是含有木质素的纸浆或纸张，抵御光的不良影响导致的黄变和变色非常有效。这些化合物在造纸过程的各个阶段添加，特别是在湿端，需要具有高亲和力的水溶性或水分散材料是必不可少的。这种性能通常通过存在于紫外线吸收剂、聚合物抑制剂、亚硝基、荧光增白剂和金属螯合剂等组中选择一个或多个共添加剂来进一步增强。羟胺或其盐、苯并三唑或苯并酮紫外线吸收剂和金属螯合剂的组合特别有效。
