一般描述

糠醇是脱脂奶粉、年糕、和蜂蜜中发现的一种挥发性风味化合物。

应用


  • Achmatowicz重排启发的绿色化学、有机方法和天然产物全合成的发展: 本研究讨论了受Achmatowicz重排启发的创新有机合成策略,重点关注了绿色化学和天然产物的合成,其中可能包括糠醇作为前体或试剂的应用(Liang et al., 2022)。

  • 溶解态黑碳的三重态光化学及其对活性氧形成的影响。: 本文考察了溶解态黑碳的三重态光化学,这可能涉及糠醇在环境基质中的光化学行为(Wang et al., 2020)。

  • 丙酮酸水溶液光化学过程中单线态氧((1)O(2))的产生:稳态O(2)(aq)浓度下pH和光子通量的影响。: 研究了丙酮酸水溶液中单线态氧的产生,该研究可能与我们对糠醇光化学性质的理解有关(Eugene and Guzman, 2019)。

  • 溶解有机物的三重态光化学:三重态能量分布和表面电荷情况。: 讨论了溶解有机物的三重态能量,这可能与糠醇在各种环境条件下的行为有关(Zhou et al., 2019)。
