Steps:

22; 23

A 1-liter, creased, 4-necked round bottom Pyrex flask equipped with mechanical stirrer, 250-milliliter (ml) addition funnel, temperature probe, heating mantle, and water-cooled total reflux condenser was used. The flask was initially charged with 200 grams (1.08 mole) of ADMA-10 (decyldimethylamine, available from Albemarle Corporation, Baton Rouge, LA), and 239 grams (1.08 mole) decyl bromide was placed in the addition funnel. The stirrer was turned on and the reactor was heated to 65°C. The decyl bromide was added dropwise to the ADMA-10 as the temperature of the reactor was allowed to rise from 65°C to 142°C. The addition funnel was then charged with 110 grams of methanol, and the methanol was added dropwise to the solution as the temperature of the reactor was allowed to fall to 90°C. After the entire volume of the methanol was added to the reaction mixture, the heat and stirring were ceased and the intermediate quaternary ammonium (quat-Br) solution was allowed to cool.
