Anaerobic digestion is a sustainable technology used in waste treatment and bioenergy production. It is chemically represented by the Buswell’s equation which is a significant model for counting theoretical quantity of biomethane. Although pure organic degradable substances or mixtures have been well studied by using Buswell’s equation, organochlorine compounds have not yet been explored. This article has three purposes. First, a new general Buswell’s equation for organochlorine compounds is deducted. Second, the impact of chlorine element in agricultural wastes on quantity of biomethane is studied. Third, the mathematical relationships among quantity of biomethane, theoretical biochemical methane potential, and biodegradability index are explored.
厌氧消化是一种用于废物处理和生物能源生产的可持续技术。用buswell方程来表示,该方程是计算生物甲烷理论量的一个重要模型。虽然纯有机可降解物质或混合物已经用buswell’s方程进行了很好的研究,但有机氯化合物尚未得到探索。本文有三个目的。首先,推导了有机氯化合物的一个新的通用buswell方程。其次,研究了农业废弃物中氯元素对生物甲烷含量的影响。第三,探讨了生物甲烷量、理论生化甲烷势与生物降解指数之间的数学关系。

The Mechanism of Friedel-Crafts Chlorination Historically Reconsidered 弗里德尔-克拉夫特氯化反应机理的历史反思
Pub Date : 2023-10-16 DOI: 10.5539/ijc.v15n2p50

This short review proposes a revision to the currently accepted textbook mechanism for the direct Friedel-Crafts chlorination of benzene. After briefly reviewing the history of Friedel-Crafts chemistry and the origins of the current textbook mechanism for the direct chlorination of benzene, it is pointed out how this mechanism is at variance with the predictions of both generalized Lewis acid-base chemistry and simple frontier orbital theory, which require that dichlorine should function as a sigma antibonding electron-pair acceptor (σ*-EPA) or electrophile (Lewis acid) rather than as a pi antibonding electron-pair donor (π*-EPD) or nucleophile (Lewis base). A modification of the currently accepted mechanism consistent with these concepts is then proposed. After reviewing the debates over the structure of the active catalyst, previous proposals for the modification of the current mechanism, and other examples in which the dihalogens function as σ*-EPA electrophiles, the revised mechanism is evaluated using DFT calculations.
这篇简短的综述提出了对目前公认的苯的直接弗里德尔-克拉夫氯化机理的修订。在简要回顾了弗里德尔-克拉夫特化学的历史和目前教科书中苯直接氯化反应机理的起源之后,指出了这种机理与广义路易斯酸碱化学和简单前沿轨道理论的预测是如何不一致的。这要求二氯应该作为sigma反键电子对受体(σ*-EPA)或亲电试剂(路易斯酸),而不是作为π反键电子对供体(& π;*-EPD)或亲核试剂(路易斯碱)。然后提出了与这些概念一致的目前接受的机制的修改。在回顾了关于活性催化剂结构的争论,先前对当前机制的修改建议,以及其他双卤素作为& σ;*-EPA亲电试剂的例子之后,使用DFT计算对修改后的机制进行了评估。

Effect of the Ferrocene Nucleus on the Microwave-Accelerated Esterification Reaction 二茂铁核对微波加速酯化反应的影响
Pub Date : 2023-09-25 DOI: 10.5539/ijc.v15n2p26
Yutaka Okada, Masashi Tachi
Microwave irradiation has been utilized in the syntheses of a wide variety of organic compounds due to its shorter reaction times and improved selectivities. Since ferrocene is an organometallic compound consisting of an iron center sandwiched between two cyclopentadienyl rings, the iron moiety was expected to efficiently absorb microwave irradiation, thereby resulting in the ferrocene molecules exhibiting an antenna effect. Thus, we herein confirmed this antenna effect by employing an esterification reaction as a model reaction, using both ferrocene and benzene derivatives under microwave irradiation and conventional heating conditions for comparison purposes. It was also found that the reaction could be carried out at lower temperature using ferrocene derivatives.
微波辐射由于其较短的反应时间和较高的选择性,已广泛应用于各种有机化合物的合成。由于二茂铁是一种有机金属化合物,由夹在两个环戊二烯环之间的铁中心组成,因此铁部分有望有效吸收微波辐射,从而导致二茂铁分子表现出天线效应。因此,我们在此以酯化反应作为模型反应,使用二茂铁和苯衍生物在微波辐射和常规加热条件下进行比较,从而证实了这种天线效应。还发现用二茂铁衍生物可以在较低温度下进行反应。

Using the Carbon-Atom Method to Determine Mean Oxidation Number of Organic Carbons 用碳原子法测定有机碳的平均氧化值
Pub Date : 2023-08-08 DOI: 10.5539/ijc.v15n2p13
Pong Kau Yuen, C. M. Lau
The notion of oxidation number acting as an electron-counting concept is crucial for balancing redox reactions, and for understanding organic and biological redox conversions. Chemical formula methods are widely used for counting oxidation numbers. There are three types of chemical formula methods. They are molecular formula method, structural formula method, and Lewis formula method. Each type has its own rules and procedures, and they are difficult for students to fully understand and remember. In addition, the capability of the molecular formula method to assign mean oxidation number of organic carbons for organic molecules or molecular ions is limited. To overcome these drawbacks, this article explores a new half reaction approach, the carbon-atom method, which can count the mean oxidation number of organic carbons for both organic and bioorganic compounds. The quantitative relationships among the number of transferred electrons, change in oxidation numbers of organic carbons, and mean oxidation number of organic carbons can also be established by balancing half organic reactions. Furthermore, the mean oxidation number of organic carbons for any given organic or bioorganic compounds with known structural formulas can be determined by using the carbon-atom method and the fragmentation operation.
作为电子计数概念的氧化数的概念对于平衡氧化还原反应和理解有机和生物氧化还原转化是至关重要的。化学式法被广泛用于计算氧化值。化学式法有三种类型。它们是分子式法、结构式法和路易斯公式法。每种类型都有自己的规则和程序,学生很难完全理解和记住。此外,分子式方法确定有机分子或分子离子的平均氧化数的能力有限。为了克服这些缺点,本文探索了一种新的半反应方法,即碳原子法,它可以计算有机和生物有机化合物的平均有机碳氧化数。通过平衡半有机反应,还可以建立转移电子数、有机碳氧化数变化和平均氧化数之间的定量关系。此外,任何已知结构式的有机或生物有机化合物的平均氧化数都可以通过碳原子法和碎片化操作来确定。

Electrical Charge Method for Balancing, Quantifying, and Defining Redox Reactions 平衡、定量和定义氧化还原反应的电荷法
Pub Date : 2023-06-05 DOI: 10.5539/ijc.v15n2p1
Pong Kau Yuen, C. M. Lau
Defining and balancing redox reactions are core knowledge and skills in the study of chemistry. The most common method to perform these two tasks is the oxidation number method, which combines mathematical operations and application of oxidation number. However, when oxidation number is not known, it is not applicable. Algebraic methods can balance all chemical reactions mathematically, but they cannot define redox reactions chemically. This article explores the electrical charge method for balancing, quantifying, and defining redox reactions. This method only requires the balancing of atoms and electrical charges. There is no need to determine oxidation number or count the number of transferred electrons. It works effectively in complicated cases where oxidation number is uncertain and where there are more than two sets of redox couples. Furthermore, the net-charge of a redox couple can function as a counting concept to determine its number of transferred electrons and change of oxidation numbers. The electrical charge method also initiates a new charge model, which complements the conventional electron model and oxidation number model, for defining redox reactions.
定义和平衡氧化还原反应是化学研究中的核心知识和技能。完成这两项任务最常用的方法是氧化数法,它将数学运算和氧化数的应用相结合。但是,当氧化值未知时,则不适用。代数方法可以在数学上平衡所有的化学反应,但它们不能在化学上定义氧化还原反应。本文探讨了平衡、定量和定义氧化还原反应的电荷法。这种方法只需要原子和电荷的平衡。不需要测定氧化值或计算转移电子的数目。在氧化数不确定和两组以上氧化还原对存在的复杂情况下,它能有效地工作。此外,氧化还原对的净电荷可以作为一个计数概念来确定它的转移电子数和氧化数的变化。电荷法还开创了一种新的电荷模型,补充了传统的电子模型和氧化数模型,用于定义氧化还原反应。

The use of therapeutic molecules in corrosion inhibition field contributes to environment preservation. In this context that this current work applies quantum chemical method to study the interaction between some metals and four compounds with antidepression effect. Which compounds are clomipramine, imipramine, amoxapine and iproniazide. The inhibition properties of these compounds in acidic media were evaluated by density functional theory (DFT) with B3LYP functional in 6-31G(d,p) basis set. It was proved that these compounds have a strong electron donating and accepting capacity. This capacity is influenced by their substituents.

治疗性分子在缓蚀领域的应用有助于环境保护。在此背景下,本研究应用量子化学方法研究了一些金属与四种具有抗抑郁作用的化合物之间的相互作用。哪些化合物是氯丙咪嗪,丙咪嗪,阿莫沙平和异丙嗪。采用密度泛函理论(DFT)评价了这些化合物在酸性介质中的抑制性能,B3LYP泛函以6-31G(d,p)为基集。结果表明,这些化合物具有很强的供电子和接受电子的能力。这种能力受取代基的影响。获得的低能隙(DE)值表明这些分子具有高活性,可以形成配位键,在金属表面建立屏障,从而减少腐蚀过程。利用福井函数(fk+, fk-)和对偶描述子(∆fkr)进行了反应位预测,发现亲核攻击的中心一般为氮原子(N),而亲电攻击的中心仅为碳原子(C)。

Two storage energy reactions, namely,carbon gasification C+CO2=2CO and Steam gasification C+H2O=H2+CO reactions were compared. The results show that the Steam gasification reaction has many advantages, such as: higher caloric value of gas, high storage energy index, faster reaction speed, abundant resources, low price, low production cost, significant emission reduction, environmental protection. Convenient for rural promotion. Water naturally can protect the earth and mankind.
