What is preparation ethylamine from acetaldehyde?

• It is also produced by reductive amination of acetaldehyde.

• CH3CHO + NH3 + H2 → CH3CH2NH2 + H2O.

• Ethylamine can be prepared by several other routes, but these are not economical.

• Ethylene and ammonia combine to give ethylamine in the presence of a sodium amide or related basic catalysts.

• H2C=CH2 + NH3 → CH3CH2NH2.

How do you prepare ethylamine?

• Ethylamine is obtained by reduction of acetamide with sodium and absolute alcohol or LiAlH4 in ether or hydrogen in presence of nickel catalyst.

How is acetaldehyde prepared from?

• Acetaldehyde can be prepared by the reduction of acetyl chloride with H2 in the presence of palladium deposited over barium sulphate along with a small amount of salt of sulphure or quinoline.

• This mixture is known as Lindlar's catalyst.

• This reaction is called Rosenmund's Reduction.

Hence, Reaction with sulfuryl chloride followed by oxidation of the sulfonamide give diethyldiazene, EtN=NEt. Ethylamine may be oxidized using a strong oxidizer such as potassium permanganate to form acetaldehyde.
