Question

CH3CH2CL2--> CH3CHO-->(H2,кат)X1-->C2H5NH2-->(CO,H2O)-->X2-->(t)X3

Answer 1

CH3-CH2-Cl2 + 2NaOH(водн.) => CH3-CHO + 2NaCl + H2O
CH3-CHO + H2 => CH3-CH2-OH
CH3-CH2-OH + NH3 => CH3-CH2-NH2 + H2O
CH3-CH2-NH2 + H20 + CO2 => (CH3-CH2-NH3)2CO3
(CH3-CH2-NH3)CO3 => CH3-CH2-NH2 + CO2 + H2O

Answer 2

Chemical Reaction Analysis

The given chemical reaction sequence involves several steps. Let's break it down step by step.

1. CH3CH2Cl2 to CH3CHO - The first step involves the conversion of CH3CH2Cl2 to CH3CHO. - This is a transformation from a dihalide to an aldehyde. - The reaction likely involves the removal of chlorine atoms and the introduction of an oxygen atom to form the aldehyde group.

2. CH3CHO to X1 (under H2, catalyst) - The next step involves the transformation of CH3CHO to X1 under the presence of hydrogen and a catalyst. - This suggests a reduction reaction, where the aldehyde group is likely converted to a different functional group.

3. X1 to C2H5NH2 - The subsequent step involves the conversion of X1 to C2H5NH2. - This indicates a further transformation of the compound X1 into an amine compound.

4. C2H5NH2 to X2 (under CO, H2O) - The next transformation involves the conversion of C2H5NH2 to X2 in the presence of carbon monoxide and water. - This suggests a reaction that modifies the amine compound into a different functional group.

5. X2 to X3 (under heat) - The final step involves the transformation of X2 to X3 under heat. - This indicates a thermal reaction that leads to the formation of X3 from the compound X2.

Conclusion

The given chemical reaction sequence involves a series of transformations starting from CH3CH2Cl2 and culminating in the formation of X3 through several intermediate compounds. Each step likely involves specific reagents and conditions to facilitate the desired chemical changes. If you have specific details about the reagents and conditions used in each step, it would be helpful to provide them for a more precise analysis.
