Reaction conditions for the elimination of chloride-ether
The conditions for the elimination reaction between the two were usually an alcoholic solution and heating. The elimination reaction could also be carried out under other conditions by heating. In the elimination reaction, the hydrogen atom on the adjacent carbon atom and the hydrogen atom left at the same time to form a double bond, producing ethene gas and hydrogen Cl3 gas.

Reaction conditions of iron, chloride-iron and chloride-iron
The reaction conditions for the reaction of iron and Cl2 to form FeCl3 were as follows: - Under ignition, iron and Cl2 react to form FeCl3. The reaction equation is [2Fe3 + 3Cl2]{=[2Fe3 + 3Cl2]} 2FeCl_{3}\)。 - Under heating conditions, the dry iron combined with the Cl2 to form FeCl3. - Iron would undergo a passive reaction in the dry Cl2 at room temperature, and it would react in the humid Cl2. The reaction pathway and products would change with the conditions. When heated, the main reaction would be a chemical reaction to produce iron chloride-like iron. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the conditions for the color reaction of iron chloride?
Most of the compounds with the structure of a hydrogen radical and an sp2 hybrid carbon atom (that is, the carbon atom on the carbon-carbon double bond) could undergo a color reaction with the water solution of FeCl3. The alcoholic group was directly connected to the aromatic ring, which was equivalent to a dilute alcohol structure, so there was also this reaction. The colors of different compounds were different. For example, the colors of the compounds of the two compounds were blue-purple, the colors of the compounds of the two compounds were green, and the colors of the compounds of the two compounds were blue. The reaction mechanism was generally believed to be the formation of a complex and color development. The iron chloride-like reaction was widely used to identify substances with enol structures. Sp2 hybrids were formed by one s orbital and two of the three p orbitals on the same layer. They were mostly used to form two single bonds and one double bond, which formed alkene, aldo, keto, and acyl in organic matter. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Pentaerythrite with Allyl Chloride
The preparation method of the diallyl-ether of pentaerythrite includes adding into a reaction kettle, a dilute solution of the potassium ether and a three-phase phase transfer catalyst.(such as tbab/al2O3 three-phase phase transfer catalyst), stirring and raising the temperature under normal pressure, and then adding allylchlorideas a blocking agent to obtain the crude product of the diallylether. The subsequent operations such as filtering the mixture to recover the three-phase phase transfer catalyst, separating the water layer and the organic layer, removing the light boiling matter by normal pressure, and obtaining the product by reduced pressure, etc., still needed to be carried out. In the preparation of Pentaerythriol Allyl Ether, there was a method of reacting allyl-chloride-base-type catalyst and Pentaerythriol in a certain mole ratio under the effect of a phase transfer catalyst (such as, for example, the effect of the four groups of tributyl-amine). However, there were some shortcomings such as large equipment investment, low reaction conversion rate, large amount of waste water generated, high cost, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of calcium chloride-magnesiumsulfuric acid
The double decomposition reaction between the two would result in the formation of a preciptate of calcium sulphate. The conditions for the metathesis reaction were to produce a deposit, water, or gas. As long as one of the conditions was met, the reaction would occur. When the two were mixed together, as long as the amount of calcium sulfuric acid produced exceeded this ratio, there would be precipitations. Moreover, the two could not prevent the formation of precipitations when mixed together. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reaction between bichromate and hydrogen chloride?
Dichromate has a strong oxidisation, and the-1-valency of the Cl-in-Cl-can be reduced. The two can react, for example, the reaction of K2Cr2O7 with concentrated HQ: K2Cr2O7 + 14HQ (concentrated)= 2KC1 + 2CrCl3 + 6Cl2 ^+7H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of the soda and the acidic barium-chloride2
When the reaction of Na2CO3 and BaCl2 was carried out, the effect of acid on the reaction should be considered. If the acid is sulfuric acid, then add sulfuric acid to the solution of potassium chlorideto react with the reaction of the solution of sulfuric acid with the solution of sulfuric acid. The reaction is as follows: 1. The reaction between the soda ash and the sulfuric acid occurred first. - \(Na_2CO_3 + 2HCl = 2NaCl + H_2O+CO_2↑\)。 - When there was an excessive amount of sulfuric acid in the solution, the carbon dioxide ions (<anno data-annotation-id ="00000000 - 4150 - 4000-a150-a160-a1500000000"> CO3 </anno>^{2 - }</anno>) in the solution would be completely converted into carbon dioxide (<anno data-annotation-id ="33c00a77 - 4150 - 4000-a150-a1500000000000"> CO2 </anno>) and escape. At this time, the solution was added to the solution. Since there were no more carbon dioxide ions in the solution, the reaction between the two would not occur (<anno data-annotation-id =" 2a2a7a8 - 4a7a7a8-a75000000000"> Na2a2c1"> Na2CO3 + BaCl2 =" Ba 2. If the amount of acid was not enough to react with all the carbonate-based ions, then the remaining carbonate-based ions in the solution would react with the barium-based ions to form a preciptate: - \(Na_2CO_3+BaCl_2 = BaCO_3↓+2NaCl\)。 Generally speaking, the reaction between the soda ash and the acidic barium-chloridedepended on the amount of acid. When the amount of acid was sufficient, no precipitations of barium-carbon would be produced, but when the amount of acid was insufficient, precipitations of barium-carbon would be produced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Principle of Dehydrating Alcohol into Ether
The alcohol group was first protonated, and then the oxygen atom of the other alcohol group attacked the protonated carbon with a pair of electrons, causing an Sn2 reaction, and then deprotonated to give ether. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Bromic Ether and Alkaline Water
The reaction between the two reagents was as follows: CH3CH2br + H2O = CH3CH20H + Brr. It should be noted that this reaction was different from the reaction between bromic ether and an alcoholic solution of soda. The latter was an elimination reaction that produced ethene. In the reaction system of bromoether and the solution of water, although the solution of water was dissolved in alcohol, the two were not mutually dissolved. Moreover, bromoether was easily dissolved in alcohol. However, the elimination reaction of bromoether was not the main reaction. Because alcohol was a protic reagent, and the two reagents were strong nuclophile bases and had no steric hindrance, the main reaction forms were base decomposition and solvation. In addition, the decomposition of Bromoether in pure water was very weak. When dilute sulfuric acid and silver nitrates were added directly to Bromoether, there would be no pale yellow precipitations. That is, the silver nitrates could not directly detect the existence of Br, so the solution must first be acidic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Acid with Glylene Butoxy Ether
Glylene butoxy ether could be used to react with some acid or acids to produce some important organic compounds. However, no special reaction of Glylene butoxy ether in Henan was found. From the chemical principle, the reaction should follow the general reaction law of Glylene butoxy ether and acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
