1. **饱和类含硫化合物(硫醇、二硫化物和硫醚)** - 反应方程式:在加氢精制条件下,\(C - S\)直接裂化成饱和烃和硫化氢(以硫醇\(C_{2}H_{5}SH\)为例)\(C_{2}H_{5}SH + H_{2}=C_{2}H_{6}+H_{2}S\)。 - 现象:饱和类含硫化合物较容易脱除,在加氢精制过程中,在催化剂和氢气的作用下,\(C - S\)键断裂,生成相应的饱和烃和硫化氢气体。 2. **噻吩** - 反应方程式: - 直接加氢氢解脱硫路径:\(C_{4}H_{4}S + 4H_{2}=C_{4}H_{10}+H_{2}S\)(产物为丁烷和硫化氢); - 先加氢饱和后加氢氢解脱硫路径(最终产物同样为丁烷和硫化氢)。 - 现象:噻吩在加氢精制过程中,通过两种路径进行加氢脱硫反应,最终都转化为丁烷和硫化氢,在反应过程中,需要在适宜的温度、压力、催化剂等条件下,使噻吩中的硫原子以硫化氢的形式脱除。 3. **苯并噻吩** - 反应方程式:苯并噻吩经过加氢脱硫后产物主要含有乙苯和少量的二氢苯并噻吩,最终产物为乙苯和硫化氢,但具体反应历程较为复杂。 - 现象:在加氢精制反应条件下,苯并噻吩逐步反应,最终生成乙苯和硫化氢,反应过程中,分子结构发生变化,硫原子逐步被脱除。 4. **二苯并噻吩** - 反应方程式: - 直接加氢氢解路径和先加氢饱和后加氢氢解路径(以直接加氢氢解路径动力学反应速率更快),最终产物为乙苯和硫化氢。 - 现象:在加氢精制反应体系中,二苯并噻吩在催化剂作用下,按照相应路径进行反应,将分子中的硫以硫化氢形式脱除,转化为其他产物。 点击前往免费阅读更多精彩小说

The Reaction Formula and Phenomenon of Zine and Ammine

The simple element of the zincs could not react with the nitrogen. If it was the formation of a complex, it was the reaction of the zinc-ion and the aqua-solution to form (Zn(NH3)4)^2 +. The reaction equation was zn2 + +4nh3·H2O=(Zn(NH3)4)^2 + +4h2o. However, there was no video teaching content about this reaction phenomenon, so he could not answer accurately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction Formula and Phenomenon of Styrene and Polyethersulphone

Styrene ($C8H8 $) and Polyethersulphone (which had a complex structure and was briefly recorded as PES. Its molecular chain contained functional groups such as ether bonds and sulphone groups) were generally difficult to directly carry out simple reactions. Under certain conditions, such as complex organic reaction mechanisms such as free radical initiation, it may occur. However, this was a complicated process, and a simple and schematical reaction equation (assuming that a apped reaction occurred) might be as follows (it was only a schematics, the actual reaction was much more complicated): $nC8H8 + mPES/stacking {initiator and other conditions}{long right arrow}$Poly (complex structure, it is difficult to accurately write the specific structure here) Phenomena: If the reaction is carried out in a solution system, as the reaction goes on, the solution may change in terms of the initial low density. This is due to the formation of a larger molecular weight of the initiator. If there is a thermal change in the reaction, there may be a temperature increase or external temperature control may be needed to maintain the reaction temperature. Moreover, the reaction system might change from the initial uniform and transparent state to turbid as the reaction progressed or the product was separated. However, this depended on the specific reaction conditions and the composition of the system. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Sulfur and Metal Reaction Formula and Phenomenon Diagram

The following is a summary of the equations and phenomena of the reaction between sulfur and metals: 1. ** Sulfur and Iron Reaction ** - The equation is: FeS ${stack}{triangle}{=}=}$ FeS (Iron Sulphide, dark brown) - [Phenomenon: Iron powder and sulfur powder are mixed and heated to red heat. The reaction produces a black solid that releases a lot of heat.] 2. ** Sulfur and Copper Reaction ** - The equation: 2Cu + S $\stacking rel {\triangle}{=\!=}$ Copper Sulfur (black) - [Phenomenon: The reaction produces a black solid.] 3. ** Sulfur and mercury react ** - Formula: Mercury + S = HgS (Mercury Sulphide, black) - [Phenomenon: The reaction produces a black solid.] In general, when sulfur reacted with metals, sulfur showed its oxidisation, while metals showed its reduction. The reaction formed a black solid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction Formula and Phenomenon of Acetic Acid and Alcohol

If the reaction between the hydrogen radical (-OH) in gly colic acid and the hydrogen radical (-COOH) in the sulfuric acid occurs, the esterfication reaction will occur. The reaction equation is: gly colic acid + sulfuric acid → sulfuric acid + water. Esterification reactions required acidic conditions to promote the reaction. The reaction was an equilibrium reaction, and the degree of reaction depended on factors such as the concentration of the reagents, temperature, and reaction time. Usually, the presence of an acidic catalyst, such as sulfuric acid or lithium sulfuric acid, was required. If it was the reaction of the metal, the essence of the reaction was the replacement of the hydrogen in the starch group by the Na. The reaction equation was: 2CH3COCOON +2Na→ 2CH3COONa +H2. The phenomenon was that the Na floated on the surface of the liquid, melted into a small ball, and swam around, making a hissing sound. If it was the reaction of sulfuric acid and sulfuric acid, the reaction equation was: CH3COON + NaOx → CH3COONa +H2O, and there was no obvious reaction. If it was the reaction of sulfuric acid and carbon dioxide, the reaction equation was: 2CH3COON + Na2CO3 → 2CH3COONa +CO2 → +H2O, and the phenomenon was the formation of bubbles. If it was the reaction between sulfuric acid and hydrogen dioxide, the reaction equation was: CH3COON + NaHCO3 → CH3COONa +CO2 → +H2O, and the phenomenon was the formation of bubbles. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction Formula and Phenomenon of Ferrous Oxid and Acid

The chemical equation of the reaction between iron dioxide and hydrogen iodate is: FeOx +2Hi = FeI Ox +2H Ox, and the ion equation is: FeOx +2H Ox = FeOx +2H Ox. As for the reaction phenomenon, since the iron dioxide was a white solid and the hydrogen iodate was a colorless solution, the iron dioxide produced after the reaction was a colorless solution, and the water was a colorless liquid, the phenomenon was that the white solid gradually dissolved and the solution became colorless. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction Formula and Phenomenon of Electrolyzed SodiumSulphate and SodiumHydride

The essence of the process of producing an electrolyser solution was water, and the reaction equation was: 2H ^O = Electrolyser = 2H ^^+ O ^^(In the solution of sulfuric acid, sulfuric acid acts as a conductor and does not participate in the electrolyser reaction). The phenomenon was that the positive pole produced a colorless gas (oxygen), and the negative pole produced a colorless gas (hydrogen), and the volume of hydrogen was about twice the volume of oxygen. The chemical equation for the decomposition of the solution itself is: 2H ^O +2e = H ^+20H (the negative reaction), 40H-4e = O ^+2H O (the positive reaction), and the general reaction equation is: 2H O = decomposition ^= 2H ^+ O ^. The phenomenon is also that the positive pole produces colorless gas (oxygen), and the negative pole produces colorless gas (hydrogen). The volume ratio of hydrogen to oxygen is about 2:1. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction Formula and Phenomenon of the Reaction between Thiodic Cyanate and Silver Nitrate

When there is a small amount of thiodic acid, the reaction equation is: \(Ag^{+}+SCN^{-}=AgSCN\). The phenomenon is the formation of a white deposit. This deposit is not dissolved in dilute sulfuric acid, but is easily dissolved in the presence of hydrogen. When heated with concentrated sulfuric acid in a water bath, it will completely dissolve. When there was an excess amount of thianate, the reaction equation was: [AgSCN + NH4] SCN = NH4](AgSCN) 2]. The phenomenon was that the white deposit formed first dissolved and a colorless solution was obtained. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
