  偶氮苯的热异构化。三、取代基、溶剂和压力对推拉偶氮苯热异构化的影响

  摘要：

  研究了取代基、溶剂和压力对 4-二甲氨基-4'-硝基偶氮苯 (NDAAB) 衍生物的热顺反异构化速率的影响。2-甲基-和 2'-氯-NDAAB 异构化速度比 NDAAB 快，2'-甲基-和 2-氯-NDAAB 异构化速度比 NDAAB 慢。对于 2,2'-二甲基-和 2,2'-二氯-NDAAB，速率介于单取代的速率之间。这些发现与 4-（二甲氨基）偶氮苯 (DAAB) 衍生物的发现非常相似，在 NDAAB 和 DAAB 之间没有观察到动力学取代基效应的根本差异。活化体积为负值，随溶剂和取代基的不同而显着变化；它的大小通常随着溶剂极性的增加而增加。即使对于 DAAB 和 4，4'-双（二乙氨基）偶氮苯 (BDEAAB)，极性溶剂中的外部压力可明显加快该速率。得出的结论是，观察到的结果与逆...

  An organic compound having an affinity for a resin of a molded resin article and sublimation properties is allowed to penetrate/disperse into the surface of the molded resin article, thereby modifying and/or coloring a resin surface layer. The molded resin article and the organic compound having the affinity for the resin and the sublimation properties are put into a tightly closable container, and the pressure and the temperature in the container are adjusted to place them in a saturated sublimation pressure state of the organic compound, whereby a vapor of the organic compound is uniformly deposited on the surface of the molded resin article and it further penetrates/disperses into the resin surface layer, and in consequence, the resin surface layer can be modified and/or colored. In addition, the modification of the resin surface layer permits imparting a function thereto.
