  formed on primitive Earth by the formose reaction. However, their formation is not fully understood and it is plausible that key intermediates could have formed in extraterrestrial environments and subsequently delivered on early Earth by cometary bodies. 1,2-Ethenediol, the enol form of glycolaldehyde, represents a highly reactive intermediate of the formose reaction and is likely detectable in the

  益生元糖被认为是在原始地球上通过甲醛反应形成的。然而，它们的形成尚不完全清楚，关键中间体可能是在地外环境中形成的，随后由彗星体运送到地球早期，这似乎是合理的。1,2-乙二醇是乙醇醛的烯醇形式，代表了甲醛反应的高反应性中间体，很可能在星际介质中可检测到。在这里，我们通过旋转光谱技术报告了 ( Z )-1,2-乙烯二醇的鉴定和首次表征。标题化合物已通过 bis -exo的快速真空热解在气相中产生-5-norbornene-2,3-diol，在 750 °C 下，通过逆 Diels-Alder 反应。光谱分析由高级量子化学计算指导，该计算预测的光谱参数与实验非常一致。我们的研究提供了准确的光谱数据，可用于在星际空间中搜索 ( Z )-1,2-乙烯二醇。

  sugars. It exists in solid state, only in crystalline dimeric form as 2,5-dihydroxy-1,4-dioxane. However, in solution phase or during heating, it dissociates into different dimeric and monomeric forms. FTIR spectroscopy was used to study the effect of temperature, pH and solvent on the dissociation and chemical transformations of glycolaldehyde. The infrared spectra were recorded in different solvents as

  摘要乙二醇醛代表最简单的α-羟羰基部分-还原糖的常见结构特征。它以固态存在，仅以2,5-二羟基-1,4-二恶烷的结晶二聚体形式存在。但是，在溶液相或加热过程中，它会分解成不同的二聚体和单体形式。FTIR光谱用于研究温度，pH和溶剂对乙醇醛的离解和化学转化的影响。红外光谱是在30至85°C的时间和温度（加热和冷却循环期间）的函数下记录在不同溶剂中的。在加热期间，乙醇醛环状二聚体在羰基区域产生两个带，一个在1744cm -1，另一个在1728cm -1。这些带在加热周期中增加而在冷却周期中减小。数据表明，乙醇醛环状二聚体（2,5-二羟基-1,4-二恶烷）经历开环形成无环二聚体（1728 cm -1），该无环二聚体可再循环为2-羟基甲基-4-羟基-1 ，3-二氧戊环结构。无环二聚体还可以与烯二醇形式（1703cm -1）平衡解离成单体乙二醛（1744cm -1）。有证据表明，在中性或碱性水溶液中，加热期间乙醇醛会氧化成乙醇酸。

  Semiconductors such as ZnO and TiO2 have been extensively utilized in the photocatalytic degradation of dyes. However till date, no study has been reported to compare the catalytic efficiency of such organic-inorganic hybrids under UV light and microwave irradiation separately. The present work reports the synthesis of poly(1-naphthylamine)/ZnO nanohybrids. The structure and morphology of the synthesized nanocomposites were characterized using FT-IR, DV, XRD, TEM and Cyclic voltammetry analyses. The dye degradation studies were done separately in a photochemical reactor and in laboratory microwave oven and the fragments were identified using LC-MS technique. Results showed that under microwave irradiation, the efficiency of ZnO/PNA as catalyst was higher as compared to DV irradiation. Higher extent of center dot OH radical generation was confirmed in microwave as compared to UV irradiation which was found to be responsible for the high rate of degradation of dye solution. A plausible degradation pathway was proposed. (C) 2016 Elsevier B.V. All rights reserved.
