Secondary amines form yellow oily N-nitrosamines with nitrous acid. N-methylethylamine and N-ethylaniline are secondary. Primary aliphatic amines lose N 2 ​ , tertiary aliphatic amines form salts, and N,N-dimethylaniline undergoes ring nitrosation rather than the stated oily nitrosamine reaction. Total 2.
