Higher aliphatic amine or its salt when treated with ethylene oxide reacts to produce the quaternary ammonium compounds as shown in authors' report No. 2 and No. 3. Instead of ethylene oxide, propylene oxide was used in this reaction. Tertiary amine having no or little steric hindrance reacts with propylene oxide to produce the quaternary ammonium compound. But the reaction of secondary amine was difficult and primary amine did not react. These reactivity to produce the quaternary ammonium compounds depends on the back Estrain of 2-hydroxy-propyl radical formed by addition of propylene oxide to secondary and primary amine. Quaternary ammonium salt obtained from this method showed good surface activity.
