PROBLEM TO BE SOLVED: To solve the problem that a method for producing an N,N'- dialkylimidazolinium quaternary salt by one-step reaction because a conventional method for producing the N,N'-dialkylimidazolinium quaternary salt requires a multistep process, and is industrially insufficient. SOLUTION: This method for producing the N,N'-dialkylimidazolinium quaternary salt from nitriles and an N,N'-dialkyldiamine is carried out in the presence of an acid.
