Question

как из COH получитьC2H5OH как из C2H5OH получить C4H10 за ранее спасибо

Answer 1

из COH получить невозможно, а вот из CH3CHO можно:

CH3CHO + H2 -->C2H5OH(этанол)

 C4H10 в одну стадию вроде нельзя получить из C2H5OH

С2Н5ОН --(H2SO4)--> С2Н4 + Н2О (дегидратации)

С2Н4 + НСl --> C2H5Cl

2C2H5Cl + 2Na = C4H10 + 2NaCl

How to obtain C2H5OH from COH?

To obtain C2H5OH (ethanol) from COH, you would need to perform a series of chemical reactions. Here is a general outline of the process:

1. Dehydration of COH: The first step is to remove water (H2O) from COH. This can be achieved by using a dehydrating agent such as concentrated sulfuric acid (H2SO4). The reaction can be represented as follows:

COH + H2SO4 → C2H4 + H2O

This reaction produces ethene (C2H4) and water (H2O).

2. Hydration of C2H4: The next step is to add water (H2O) to ethene (C2H4) to produce ethanol (C2H5OH). This reaction is called hydration and is typically carried out in the presence of a catalyst such as phosphoric acid (H3PO4). The reaction can be represented as follows:

C2H4 + H2O → C2H5OH

This reaction produces ethanol (C2H5OH).

Please note that the actual reaction conditions and specific reagents used may vary depending on the laboratory or industrial process. It is important to follow proper safety protocols and consult reliable sources or experts for detailed instructions.

How to obtain C4H10 from C2H5OH?

To obtain C4H10 (butane) from C2H5OH (ethanol), you would need to perform a series of chemical reactions. Here is a general outline of the process:

1. Dehydration of C2H5OH: The first step is to remove water (H2O) from C2H5OH. This can be achieved by using a dehydrating agent such as concentrated sulfuric acid (H2SO4). The reaction can be represented as follows:

C2H5OH → C2H4 + H2O

This reaction produces ethene (C2H4) and water (H2O).

2. Hydrogenation of C2H4: The next step is to add hydrogen (H2) to ethene (C2H4) to produce butane (C4H10). This reaction is called hydrogenation and is typically carried out in the presence of a catalyst such as nickel (Ni) or platinum (Pt). The reaction can be represented as follows:

C2H4 + 2H2 → C4H10

This reaction produces butane (C4H10).

Again, please note that the actual reaction conditions and specific reagents used may vary depending on the laboratory or industrial process. It is important to follow proper safety protocols and consult reliable sources or experts for detailed instructions.
