"Quaternary ammonium compounds are prepared by the alkylation of tertiary amine. Industrial production of commodity quat salts usually involves hydrogenation of fatty nitriles, which can generate primary or secondary amines. These amines are then treated with methyl chloride. The quaternization of alkyl amines by alkyl halides is widely documented. In older literature this is often called a Menshutkin reaction, however modern chemists usually refer to it simply as quater… " - Quaternary amine groups
