  一种制备二羟丙基羟胺的方法

  摘要：

  一种制备二羟丙基羟胺的方法，包括：S1、将双氧水溶液和酸酐混合得到氧化液；S2、将二羟丙基胺与溶剂混合，加入S1中的氧化液中进行氧化反应；S3、所得的氧化产物与萃取溶剂接触进行溶剂萃取，得到的萃取液为酸酐和有机溶剂，得到的萃余液为亲水溶剂和二羟丙基羟胺，所述的萃余液经减压蒸馏脱除亲水溶剂后得到二羟丙基羟胺产品。本发明以酸酐和双氧水为氧化剂，二羟丙基胺为原料，仅需一步反应即可制备二羟丙基羟羟胺化合物，该方法原料廉价易得，反应收率高、产品提纯容易，得到的二羟丙基羟胺产品纯度高。

• 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。
