Acetylene appear as gas and is unstable and thus kept in presence of other solution such as liquid ammonia.
Ethanol on reacting with ammonia produces ethylamine as follows:
[tex]CH_3CH_2OH + NH_3 -> CH_3CH_2NH_2 + H_2O[/tex]
Ethanol again on reacting with ethylamine produces diethylamine and triethylamine as follows:
[tex]CH_3CH_2OH + CH_3CH_2NH_2 -> (CH_3CH_2)_2NH + H_2O[/tex][tex]CH_3CH_2OH + (CH_3CH_2)_2NH -> (CH_3CH_2)_3N + H_2O[/tex]
