  摘要：

  Three new 2,5-dihydroxy-3-alkyl-1,4-benzoquinones, (Z)-2,5-dihydroxy-3-(pentadec-8-enyl)-1,4-benzoquinone, (Z,Z)-2,5-dihydroxy-3-(heptadeca-8,11-dienyl)-1,4-benzoquinone and (Z)-2,5-dihydroxy-3-(heptadec-8-enyl)-1,4-benzoquinone and the known 2,5-dihydroxy-3-pentadecyl-1,4-benzoquinone were isolated from the leaves of Embelia angustifolia. Their structures have been established on the basis of spectral analysis and by chemical methods. Copyright (C) 1997 Elsevier Science Ltd.

  dominant role of iodic acid (HIO3) in iodine-driven particle formation. Here, we report flow tube laboratory experiments that solve these discrepancies by showing that both IxOy and HIO3 are involved in atmospheric new particle formation. I2Oy molecules (y = 2, 3, and 4) react with nitrate core ions to generate mass spectra similar to those obtained by CIMS, including the iodate anion. Iodine pentoxide (I2O5)

  碘化学是海洋和极地边界层中新粒子形成的重要驱动力。然而，关于碘气体到粒子的转化是如何进行的，存在着相互矛盾的观点。实验室研究表明，碘的光氧化会产生碘氧化物 (I x O y )，这是众所周知的粒子前体。相比之下，在现场和环境室研究中的硝酸根阴离子化学电离质谱 (CIMS) 观察结果已被解释为碘酸 (HIO 3 ) 在碘驱动的粒子形成中的主要作用的证据。在这里，我们报告了通过显示 I x O y和 HIO 3来解决这些差异的流管实验室实验参与大气新粒子的形成。I 2 O y分子（y = 2、3 和 4）与硝酸根核心离子反应生成类似于 CIMS 获得的质谱，包括碘酸根阴离子。由高阶 I x O y光解产生的五氧化二碘 (I 2 O 5 )可能被水二聚体水解，产生 HIO 3，这也有助于碘酸盐阴离子信号。我们估计，硝酸盐 CIMS 在大气水蒸气浓度下观察到的碘酸盐阴离子信号中约有 50% 来自 I

• A new type of oxyhalogen oscillator: the bromite-iodide reaction in a continuous flow reactor
  作者：Miklos Orban、Irving R. Epstein

  DOI：10.1021/ja00030a021

  日期：1992.2

  The reaction between bromite and iodide ions in a flow reactor shows two steady states and sustained oscillations in pH, redox potential, and [I-]. The oscillatory behavior is extremely sensitive to the inflow ratio [BrO2-]/[I-], the flow rate, the initial pH of the input solutions, and the stirring rate. Batch experiments suggest that the system behaves in several respects like the analogous chlorite-iodide oscillator. The bromite-iodide system, however, is also a pH oscillator and is the first oxyhalogen oscillator to oscillate in the neutral and basic pH range.

• On the Complexity of Kinetics and the Mechanism of the Thiosulfate–Periodate Reaction
  作者：Evelin Rauscher、György Csekő、Attila K. Horváth

  DOI：10.1021/ic2006309

  日期：2011.6.20

  The thiosulfate-periodate reaction has been studied spectrophotometrically in a slightly acidic medium at 25.0 +/- 0.1 degrees C in an acetate/acetic acid buffer by monitoring the absorbance in the 250-600 nm wavelength range at a constant ionic strength adjusted by the buffer component sodium acetate. In agreement with a previous study, we found that the reaction cannot be described by a single stoichiometric equation, tetrathionate and sulfate are simultaneously formed, and its ratio strongly depends on the pH. As expected at certain initial concentration ratios of the reactants, the reaction behaves as a dock reaction, but after its appearance, iodine is slowly consumed mainly because of the moderate tetrathionate-iodine reaction. It is also enlightened that the initial rate of the reaction is completely independent of the pH, which apparently contradicts a previous study, which postulates a "supercatalytic" behavior of the hydrogen ion on the title reaction. Significant buffer assistance that may change the absorbance-time profiles was also observed. On the basis of the kinetic data, a robust 28-step kinetic model with 22 fitted parameters is proposed and discussed to explain adequately all of the important characteristics of the kinetic curves.
