Multiple-paths hydrogen abstraction reactions of fluorine -with CH_3OH have been investigated at the MP2/6-311 ++ g level. The potential energy surfaces for H-abstraction reaction from carbon atom and oxygen atom were given respectively. The results indicate that there is only one minimum energy path for hydrogen abstraction from carbon atom, while multiple paths were found for hydrogen abstraction from oxygen atom. All the stationary structures, frequencies as well as PES sketch of all channels were given, in which the dominant channel is by a five-member ring transition state. The calculated heat of reaction is 170.62 kj/mol for channel 1, 119.41 kJ/ mol for branch channel 6. The results are in good agreement with experimental data.

以MP2/6-311 ++g水平上详细研究了氟原子与甲醇抽氢反应的多通道反应机理,得到了各条通道中涉及的驻点的构型和振动频率及其能量,给出了两张完整的反应势能面,结果表明,氟原子从C原子上抽氢时有一条明显的最低能量通道,而从氧原子上抽氢时要涉及多条分支通道和多个驻点构型,给出了各分支通道势能面示意图,结果表明以形成五元环状过渡态通道为优势通道,计算得到经途径1生成CH_2OH时反应放热170.62kJ/mol,经分支途径6生成CH_3O自由基时反应放热119.4 kJ/mol,此结果与实验值一致。

例如,在曝气或曝氧过程中,氧气可与污水中的化合物生成有异臭味的产物;又如,在厌氧过程中,污水中的硫在微生物的作用下,生成硫化氢、硫醇和硫醚等化合物。

Objective:To observe the effct of helium-oxygen mixture on vital capacity and to evaluate the theory and application of maximal expiration flow volume curve breathing helium-oxygen mixture.

目的 :观察氦氧混合气对肺活量的影响,并根据实验数据对氦氧混合气最大呼气流速-容积曲线的理论和价值作一评价。

The analysis of decomposition mechanisms of the catalyst surface revealed that one of the mechanisms is that activated gas phase O2 captures the hydrogen of the organic pollutants to produce free radicals, which then initiate the catalytic reaction, and produce CO2 and H2O ultimately; and the other mechanism is that the activated organic compounds attack the crystal lattice oxygen, which reduces the valances of the transition metals, then the oxidant of the oxygen oxidizes the transition metals to high valances, which realize the self oxidation-reduction of the catalyst.

催化剂表面有机物降解的机理分析表明,一种反应机理为气相中的O2活化后直接夺取有机污染物的氢,产生自由基,并引发催化反应,最终生成CO2和H2O;另一种反应机理为活化后的有机物直接进攻催化剂的晶格氧,并且使得过渡金属由高价态变为低价态,反应气中的O2再将低价态的金属氧化为高价态,实现催化剂自身的氧化还原循环。

Most of insects usually don not have the hemcoyte for transporting oxygen, the respiratory of insect is chiefly accomplished by the tracheal system that spreads all over the whole body. Outside oxygen enters the tracheal system through spiracles arranged in two sides of body and is transported through trachea and tracheoles to meet directly the needs of tissues.
