The reaction temperature of the hydrogen production process was relatively stable. In different hydrogen production processes, the reaction temperature was usually within a specific range. For example, in some common hydrogen production reactions with hydrogen from gasoline, the reaction temperature was between 170 - 300 ° C. Within this temperature range, through reasonable device design, such as using a specially designed reactor, the internal heating could be more uniform and the reaction more stable. At the same time, there were also related catalyst suitable for different temperature ranges, which also helped to maintain the stability of the reaction temperature, thus ensuring the stability of the hydrogen production reaction.

The reaction mechanism of hydrogen production from gasoline mainly had the following methods: 1. The steam reforming reaction (MPR) of the gasoline was one of the most common methods. The reaction equation is CH30H + H2O → CO2+ 3H2. In this reaction, the reaction between the alcohol and water vapor occurred under the effect of a catalyst to produce carbon dioxide and hydrogen. This reaction process was relatively complicated, involving the activation of the alcohol molecules, the breaking and reassembly of chemical bonds, and many other steps. 2. The reaction equation is CH30H + 1/2O2 → CO2+ 2H2. In this reaction, the partial oxidization of the oxygen and the alcohol produced carbon dioxide as well as hydrogen. The characteristic of this method was that the reaction speed was relatively fast, but the control of the reaction process was relatively difficult. It was necessary to accurately control the amount of oxygen supplied to avoid over-oxidization or incomplete reactions. 3. Alcohol autothermal reforming (ATR): It was a hydrogen production method that combined the steam reforming reaction and the partial oxidization reaction of the alcohol. The reaction equation can be roughly expressed as CH30H + xO2 +(1 - x)H2O → CO2+ (3 - 2x)H2. This method used the heat generated by the partial oxygen reaction to supply the steam reforming reaction, thus improving the energy utilization efficiency. It had certain advantages in practical applications. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Obel used the more mature middle-pressure method of producing sulfuric acid, which was then used for the production of Aspirin. The specific production process of Salicolic acid was as follows: using the raw material of the acid as the raw material, it first reacted with the solution of NaOx to produce the solution of the acid, and then under the medium pressure (0.7 - 0.8MP), carbon dioxide was introduced to carry out the hy droxidation reaction to produce the solution of the acid, and then the crude product of Salicolic acid was produced by sulfuric acid. Finally, the crude product of Salicolic acid was refined by sublimation. However, the document did not give the reaction process of producing spirillic acid. Sorry, I can't give an accurate answer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In the process of oxygen free breathing, the reduction of hydrogen and the reaction of Ruvic acid could produce actic acid. In addition, the reaction of Ruvic acid with the reduction of hydrogen could produce alcohol, but not Ruvic acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

When the ratio of the reaction between the two was 1:1, the chemical equation was NaHSO4 +Ba(SH)2==H2O+ NaOx + BaSO4. The reaction produced water, the precipitations of soda, and the precipitations of bis sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction mechanism between alkyls and halos was a substitution reaction of free radical. In the reaction, the halo (such as pure chorine, pure bromine, and not chorine water or bromine water) under the conditions of light/heat/free radical initiator, X-X was split into two X-free radical, X -and the HX-H on the alkyls formed hydrogen halo, and the alkyls left the alkyls free radical, which then reacted with X-X to form X -, and the cycle reaction could continue. The reaction between an aromatic compound (such as alkyne and alkyne) and a hydrogen atom was mainly an addition reaction. The double bond in an aromatic compound was a sigma-bond and a pi-bond. The pi-bond was more unstable and easy to break. The double bond opened to become a single bond, and the broken small half bond formed a covalent-bond with the hydrogen atom. In addition, the addition reaction of the hydrogen atom with the unsatured carbon could also be carried out. Aromatic compounds could only be substituted with a catalyst (such as iron trihalide, aluminum trihalide, iron powder, etc.), except for very active compounds (such as aromatic amine, vitamins, etc.). Fatty acid could only be substituted with a catalyst of red phosphorus, which generally produced an alpha substituted product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The mixture of hydrogen peroxide-hydrogen peroxide-acid and hydrogen iodinate-acid would result in an oxido-reduction reaction. The reaction equation is [H2O2 + 2Hi]. In this reaction, the valency of the oxygen element in the hydrogen peroxid decreased from-1 to-2, showing its oxidisation, while the valency of the iodine-element in the hydrogen iodinate increased from-1 to 0, showing its reduction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There were different views on the reaction of hydrogen and alcohol. One view was that the reaction between alcohol (CH3CH20H) and hydrogen peroxid (H2O2) could produce esh (CH3Cho2) and water (2H2O), that is, CH3CH20H + H2O2 = CH3Cho2 + 2H2O. The other view was that there would be no change after mixing the two, and there would be no chemical reaction, especially when the hydrogen peroxid was medical grade. If the hydrogen peroxid was 100% concentrated, it would explode directly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
