Write the equations of chemical reactions, with the help of which you can carry out a number

Write the equations of chemical reactions, with the help of which you can carry out a number of transformations corresponding to the scheme: ethanol — propyl ester of acetic acid. Indicate the condition of their flow.

Let’s write the equations:
C2H5 – OH + CuO = CH3 – CHO + Cu + H2O – oxidation of ethanol, acetaldehyde obtained;
CH3 – CHO + Ag2O = CH3COOH + 2Ag – reaction of a silver mirror, acetic acid is released;
CH3COOH + C3H7 – OH = CH3COO – C3H7 + H2O – esterification, the propionic ester of acetic acid was obtained.
The reactions show the bond of oxygenated organic substances. Acetic acid propionic ester is used as a solvent and in the food industry for the preparation of essences.
