    摘要:
    通过使用单色光,在 313-366 nm 的波长范围内研究了十个 1,5-己二烯-3-酮在甲醇中的光化学。为了了解对 5-methyl-1,5-hexadien-3-one (1) 观察到的不寻常的波长依赖性选择性,进行了量子产率测量、结构反应性研究、三线态敏化和淬火实验。虽然 10 项二烯酮研究中有 6 项显示选择性与 313 至 366 nm 的辐射波长无关,但有 4 项二烯酮表现出与波长相关的选择性,与 1 中观察到的相似,因此确定 1 不是唯一的,以前认为. 三线态敏化研究表明,波长依赖性主要来自以三线态环加成完成的单态α-裂解反应。多种三线态猝灭剂在抑制这些反应方面是无效的。讨论了一些可能的机制

The coagulation liquid preferably contains 1 to 10,000 ppm of a carboxylic acid, 1 to 50,000 ppm of a carboxylic acid ester, or 1 to 15,000 ppm of a carboxylic acid salt. It is preferred as well that the water content of the continuously produced EVOH pellets be adjusted to 20 to 80% by weight and then brought into contact with an aqueous solution, having a specified concentration, of at least one compound selected from the group consisting of a boron compound (B), an acetic acid salt (C) and a phosphoric acid compound (D). Furthermore, the thus-obtained EVOH pellets are subjected to drying treatment by a combination of stationary drying and fluidized drying.
