Under the condition of light, the reactants are allowed to react with a low concentration of Cl2, and the main reaction in this step is.
c6h5—c(ch3)=ch2 + cl2 → c6h6—c6h5-c(ch2cl)=ch2 + hcl
Due to the conjugation effect, this reaction has a great tendency to occur, and the addition reaction is difficult to occur) and then reacts with the base in an alcohol solution.
C6H5—C(CH2Cl) = CH2 + NaOH (ethanol) C6H5-C(CH2OH) = CH2 + NaCl
After that, it is oxidized with a selective oxidant, which can be oxidized by using active MNO2, etc.
C6H5—C(CoOH)=CH2.

First, a large amount of chlorine gas is used to ensure the trichloride substitution product, and the light replaces the hydrogen at the alpha position, and then hydrolyzed into alcohol, and then the three hydroxyl groups on a carbon are unstable, and it is automatically dehydrated into carboxylic acid.
c6h6-c(ch3)=ch2+3cl2 ——c6h6-c(ccl3)=ch2+3hcl
c6h6-c(ccl3)=ch2+2h2o——c6h6-c(cooh)=ch2
If you use an oxidizing agent, be careful to oxidize it into benzoic acid!

The second step on the first floor is not in the alcohol solution, but in the aqueous solutionReplace hydrogen on saturated carbon under light conditions.
The answer on the second floor, if it is high school chemistry, is not advisable, it is not a common method, although it may achieve the goal.

Summary. Pro, the process of converting CH3CH(CH3)CH2CH2OH to CH3CH(CH3)CH2NH2 requires two steps. The first step is to dehydrate CH3CH(CH3)CH2CH2OH to obtain CH3CH(CH3)CH=CH2.
This reaction requires the use of a strong acid catalyst, such as concentrated sulfuric acid or phosphoric acid, to leave -oh and -h from the molecule to form a double bond. The second step is to reduce CH3CH(CH3)CH=CH2 in the presence of hydrogen using an aluminum-magnesium alloy to obtain CH3CH(CH3)CH2NH2. This reaction requires the use of a reducing agent, such as lithium-aluminum hydride or hydrogen in combination with a catalyst, to reduce the double bond to a single bond and replace the original -c=c- with -NH2.
What is the process of synthesis of CH3CH(CH3)CH2CH2OH from CH3CH(CH3)CH2NH2?

Safety needs to be paid attention to in the reaction process, because both the dehydration reaction and the reduction reaction involve flammable and explosive substances. In addition, this process also requires precise control of temperature and time conditions to ensure the purity and yield of the product.

CH3CH2CH2COCH3 is a ketone alcohol, also known as pyruvol, which can be obtained by reduction from CH3COCH2COOCH2CH3. The preparation method is as follows: the first search is to react CH3Coch2Cooch2CH3 with lithium aluminum hydride (LiALH4) in ether to obtain silver withered to CH3CHHch2CH2COOH.
CH3CHHch2CH2COOH was then added to the NAOH solution, and the heated front hole conversion was carried out to give CH3CHHch2CH2COONA. Finally, excess CH3COOH is added, and heat conversion again to give CH3CHHch2CH2COCH3. Reaction Equation:
1. ch3coch2cooch2ch3 + 4lialh4 → ch3chohch2ch2cooh + 4lialo2 + 2h22. ch3chohch2ch2cooh + naoh → ch3chohch2ch2coona + h2o3.
ch3chohch2ch2coona + ch3cooh → ch3chohch2ch2coch3 + nach3coo
This is mainly to see what you like, the best is to test drive the experience is better, it is recommended to fancy the safety configuration, it is really not good to choose the one that sells the most, the main thing is that you are satisfied with the most cost-effective.
It is recommended that you choose the Honor 6c In terms of appearance, the Huawei Honor 6C front sensor and front camera are symmetrically distributed, and the front is relatively simple. The back is made of metal, and the upper and lower ends are plastic, and.
There is no need to compare, similar things, I don't think it makes any sense to compare the car at this price, there must be faults, it depends on what you can accept, you can't accept those, a good-looking appearance, a good-looking interior, there is no point in comparison, and the performance does not need to be compared, and you get what you pay for.
