What's the reaction when alcohol turns into aldo?
There were mainly the following reactions: 1. In the presence of a catalyst (such as copper or silver) and heating, alcohol and oxygen react to form an aldo. Take alcohol as an example: 2CH CH ^Ox +O ^→(copper or silver, high temperature)2CH CH ^Ox +2 ^H ^O. The reaction process is from--CH ^--Ox to--CH ^Ox +H ^O. After a water is removed from a hydrogen radical (--CH+H ^O), an oxygen radical is needed to form an aldo radical (--CH ^Ox +H ^O), and two hydrogen radical consume one oxygen radical. 2. Des-Martin reagent was used to catalyze the first alcohol into an aldo. The reaction was usually completed at room temperature. After the reaction was completed, the iodines were converted from penta to tri, and the post-treatment only needed to wash off the by-products with a solution of NaHCO3. The reaction had the characteristics of short reaction time, mild conditions, and less dosage of the initiator. The reaction process was that the acetoxyl group in the Des-Martin reagent replaced the alkoxyl group of the alcohol, and the other acetoxyl group left. The carbon atom attached to the alcohol's hydrogen group was transferred to the acetoxyl group, and the alcohol was oxided to the corresponding aldo. Read more exciting novels for free

What is the difference between the reaction types of alcohol and aldo?
醇具有羟基（-OH）官能团，醛具有醛基（-CHO）官能团，它们的反应类型区别如下： - **氧化反应方面**：醇可以被氧化，在合适的催化剂（如金属铜）作用下，醇基（-OH）氧化可得醛基（-CHO），例如乙醇在铜催化下被氧化为乙醛，反应式为\(2CH_{3}CH_{2}OH+O_{2}\rightarrow2CH_{3}CHO + 2H_{2}O\);而醛的氧化反应可生成羧酸，在有催化剂存在时，醛基（-CHO）被氧化为羧基（-COOH），如\(2CH_{3}CHO+O_{2}\rightarrow2CH_{3}COOH\)。 - **还原反应方面**：醛在一定条件下（如镍粉做催化剂、加热）可以发生还原反应生成醇，反应式为\(CH_{3}CHO+H_{2}\rightarrow CH_{3}CH_{2}OH\)，醇通常没有类似醛这种典型的将官能团直接还原成其他官能团的反应类型。 - **加成反应方面**：醛能发生加成反应，例如与氢气加成;醇一般不能发生典型的双键或叁键那种加成反应。 - **缩聚反应方面**：醛可参与缩聚反应，例如酚和醛能发生缩聚反应;醇在特定情况下可以参与缩聚反应，像二元醇与二元酸之间的缩聚反应，反应形式与醛参与的缩聚反应有所不同。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
Reaction of Fehling's reagent with an aldo
The reaction between Fehling's reagent and an aldo will produce a brick-red copper dioxide (Cu2 O). During the reaction, the color of the solution may gradually change from blue to green to yellow to red. If the reaction is fast, the red deposit can be directly observed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Cyclohexone and alcohol reaction
Cyclohexanate did not react with alcohol. Cyclohexanate was an organic compound with the chemical formula C6H10O. It was a saturated ring keton with the carbon atom of the carbonyl-containing group included in the six-membered ring. It was slightly dissolved in water and was also mixed with most organic liquids such as alcohol, ether, benz, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sulfates and Alcohol Reaction
Based on context alone The reaction between sulfuric acid ester and alcohol was usually a nuclophile substitution reaction. During the reaction, the oxygen atom in the alcohol acted as a nuclophile to attack the partially positively charged central atom in the sulfuric acid ester (usually the carbon atom or sulfur atom attached to the sulfuric acid radical, depending on the specific structure of the sulfuric acid ester). For example, when a common sulfuric acid ester reacted with an alcohol, the alcohol's oxygen would replace one of the methyls in the sulfuric acid to form ether compounds and the negative ion of the methyls. The reaction conditions may vary depending on the structure of the sulfuric acid ester and the alcohol. It is usually carried out in an appropriate solution (such as an organic solution). Sometimes, a certain temperature or catalyst may be needed to promote the reaction. However, he had to be extra careful when operating reactions involving sulfuric acid ester because many sulfuric acid ester were highly toxic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between ethene and alcohol is a substitution reaction
The reaction between ethene and ethanoi was an electropathic addition reaction, not a substitution reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of alcohol and hydrogen peroxid
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>
The reaction of alcohol with the presence of acid
The reaction between the alcohol and the alcohol did not occur, even under acidic conditions. Esterification was a reaction between alcohol and acid to form an ester and water. Although the ester had a functional group, it couldn't be directly reacted with alcohol and sulfuric acid to form an ester. However, the ester could be formed by the reaction of the ester with the acid. <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>
Alcohol and what medicine have a reaction
Alcohol would react with many drugs, and the following were the common types: 1. Antibiotic drugs, such as Cephalothorins, Metronidazolin, Furazodone, etc., can cause dithiram-like reactions, such as facial flushing, headache, dizziness, nausea, vomiting, increased heart rate, decreased blood pressure, etc. 2. Sedative-hypnotic drugs: such as Diazepam, Clonazepam, Estazolam, Fenobarital, Clonazepate, Chloral Hydra, etc., can enhance the inhibition of alcohol on the central nervous system, causing drowsiness, coma, etc. 3. Antipsychotic drugs: such as Thorazobin, Permethrin, etc., can enhance the inhibition of alcohol on the central nervous system, causing drowsiness, coma, etc. 4. Antipyretic analgesics, such as flurfluralin, parkinson, and so on, can increase the risk of stomach bleeding. 5. Blood Lowering Medicines: For example, glibenclamide, Metformine, and Dimethorphan, which can cause low blood sugar reactions. Drinking hypobaric drugs such as glibenclamide, Metformine, or injecting hormone after drinking can cause blood sugar to drop too quickly, causing dizziness, palpitation, cold sweat, trembling hands, and other low blood sugar reactions. In severe cases, it can cause low blood sugar coma. During the period of taking sulphoylureas, alcohol acts as a drug-inducing agent, which can promote the metabolism of sulphoylureas and significantly shorten their half-life, thereby weakening their hypoglycemia-lowering effect. Taking biguanide hypoglycemia-lowering drugs such as phenylebiguanide after drinking may also cause acidosis. 6. Anticoagulants, such as Waradin, Heparin, etc., can enhance the inhibition of alcohol on the blood clot system and cause bleeding tendency. 7. Antihypertensives: such as nifedipine, ampiclofen, etc., can cause low blood pressure. 8. Anti-allergic drugs: such as diphenhydrarmine, clorphenamin, declorhydrrazine, cypromethadine, etc., the consequences of taking it with alcohol are similar to sedative hypnotics. 9. Anti-epilepsy drugs: such as diptoin, etc., drinking alcohol during the medication can reduce the efficacy and even induce epilepsy. 10. Anti-anginal drugs: Vasodilators such as Isosorbide dinitrate, Glycerin dinitrate, and nifetidium. Drinking alcohol while taking it can cause excessive expansion of blood vessels, resulting in severe headaches, a sharp drop in blood pressure, and even shock. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
