Abstract: A continuous process for the production of choline hydroxide includes reacting ethylene oxide, trimethylamine, and water in a reaction zone to form a reaction mixture and extracting heat from the reaction mixture. Subsequently, phase separation of the reaction mixture is induced to obtain a choline hydroxide phase and an organic liquid phase comprising trimethylamine. A choline hydroxide solution (e.g., at a concentration of about 40% to 50% by weight, based on total weight of the choline hydroxide solution) is obtained from the choline hydroxide phase.
