The Chloration Reaction of Sulfonyl Chlorides and Alkene
The following is some information about the chloration reaction between the sulfur acid and the alkene: In a synthesis method of a long-carbon chain positive ion quaternized salt, C10-C18 straight-chain or branched-chain alkene is put into a chloride-substitution reaction kettle, after nitrogen replacement, heating is carried out under stirring conditions, while maintaining a certain temperature, slowly dropping sulfuric acid chloride-ester, and reacting at a constant temperature for a period of time to obtain the corresponding alkene chloride-ester. During the reaction process, a vacuum pump is used to pump the reaction tail gas into an alky solution. There was also a method for synthesizing the chloride-substituted sulphone by using copper powder to catalyze the reaction of an alkene and a sulfuric acid chloride.In a reactor, the alkene, the sulfuric acid chlorideand the copper powder catalyst were added and dissolved in an organic solution. The reactor was stirred at 100 ° C for 6 hours. After the reaction was over, the reaction liquid was cooled to room temperature, and then the chloride-substituted sulphone was separated and purified. In this method, the catalyst was simple and easy to obtain, and the catalyst activity was high. There was no need for additional organic ligands and reagents. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What does iron react with iodines to form?
The reaction between iron and iodination produces iron dioxide (FeI <2>). The chemical equation is: FeI <2>= FeI <2>, and the reaction only requires heating. Iodine was less oxidiser than iron ions (Fe3) and could only cause iron to lose the two outermost electrons, so it formed a metal called Fe2 (II). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the reaction between iodines and sulfuric acid?
During the reaction between the two, the solution may appear dark purple or dark blue at first due to the presence of the iodine-based reagent.(In the presence of the starch indicator, the iodine-based reagent will make the starch appear dark blue.) As the reaction progressed, the color of the solution gradually changed. When the reaction approached the end point, if there was a starch indicator, the solution would turn from blue to light yellow, and finally the blue color would disappear. After the reaction was complete, the solution would be colorless. This was because the reaction of the iodine-like reagent with the sulfuric acid would gradually consume the iodine-like reagent, causing the color of the solution to change as described above. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there a reaction between sulfur dioxide and iodines? Why?
The reaction of the thiothiosulphate with the iodines. This was because the sulfur in the sulfuric acid was +2, which had a strong reduction property, while the elemental sulfur had a strong oxidization property, so the two could undergo an oxido-reduction reaction. The reaction equation was I2+ 2Na2S2O3 = 2NaI+ Na2S4O6. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What causes the reaction between iodines and thiothiosulfates?
If there was still starch in the solution, the color of the solution would suddenly change after the initial reaction. This was because of the small ion of thionate, which diffused quickly and reacted quickly with iodines. On the other hand, starch was a big molecular, which diffused slowly and reacted slowly. At the beginning, the iodines produced would react with the thiothiosulfuric acid first. Since this reaction produced a colorless substance, the solution would not change color even in the presence of starch. As the reaction progressed, the amount of thionate was very small and depleted. The generated iodines could only react with starch to form a dark blue substance, which caused the solution to suddenly change color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
