摘要：
Processes for preparing N N N trimethylethanolammonium hydroxide (choline hydroxide) and the choline hydroxide produced are described. These processes minimize the production of byproduct mono ethoxylated and di ethyoxylated choline in the product choline hydroxide. The processes generally include feeding ethylene oxide trimethylamine and water into a first reactor to create a first reactor product under temperature controlled conditions. The product of the first reactor is fed into a second reactor to form a second reactor product under uncontrolled adiabatic conditions. Finally any unreacted trimethylamine in the second reactor product is removed to form a final product comprising choline hydroxide. Additional reactors can be used for the ethylene oxide and trimethylamine reaction.
