摘要
本文对几类典型醚类化合物的水溶性、碱水(5%的Na_2SiO_3·9H_2O)溶解性和酸解活性进行了初步研究,查阅了这些醚类化合物的水溶性,并测定了其碱水溶解性、临界碱水不可溶醚当量以及在微量酸存在条件下的酸解活性,研究结果表明,对一般醚类化合物而言,当醚键中不含p-π共轭时其临界水不溶醚当量为116,临界碱水不溶醚当量为102;当醚键中含p-π共轭时其临界水不溶醚当量在56—100之间,临界碱水不溶醚当量在56—72之间,这些数据对光/热成像用活性醚化物阻溶/促溶剂的分子设计以及碱显影成像制版具有重大的指导意义。
Aqueous solubility, alkaline aqueous（5 % Na2SiO3 -9H2O） solubility and acidolysis activity of some kinds of ethers were researched in the paper. Aqueous solubility, alkaline aqueous solubility and critical-insoluble ether equivalent of these kinds of ethers were determined or refered. And aeidolysis activity of these kinds of ethers was measured also when trace amount of acid compounds exist. The results indicate that aqueous and alkaline aqueous critical-insoluble ether equivalent of ethers having no p-π conjugative effect are 116 and 102. Aqueous critical-insoluble ether equivalent of ethers having p-π conjugative effect is between 56 and 100. And alkaline aqueous critical-insoluble ether equivalent of this kind ether is between 56 and 72. The research results are very useful for molecular desigin of dissolution inhibitor/promotor for photo/thermal imaging systerm and graphic arts by alkali development.
