N,N-dimethyl-N-tetradecyl amine (ADMA®14 amine; Albemarle Corporation) (752 g, 3.12 mol) was charged into a 2-liter resin kettle and heated to 41° C. under CO2 blanket before the heating source was removed. Hydrogen peroxide (142 mL, 70%, 3.74 mol) was added over 3.5 hours. The reaction mixture was monitored by 1H-NMR (see Table below). During peroxide addition, the reaction temperature ranged from 41 to 59° C. depending on the peroxide rate of addition. At the end of addition, the slurry was poured into an aluminum pan and was left to stand in a hood over the weekend, after which time 1H-NMR showed complete conversion of the N,N-dimethyl-N-tetradecyl amine to the corresponding oxide. The resulting N,N-dimethyl-N-tetradecyl amine oxide was obtained as snow-white solid block.
