PROCESS FOR PREPARING CHOLINE HYDROXIDE FROM TRIMETHYLAMINE AND ETHYLENE OXIDE
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 f...

description | 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.
Se describen procesos para preparar hidróxido de N, N,N-trimetiletanolamonio (hidróxido de colina) y el hidróxido de colina producido. Estos procesos minimizan la producción del subproducto colina monoetoxilada y dietoxilada en el producto hidróxido de colina. Los procesos generalmente incluyen alimentar óxido de etileno, trimetilamina y agua en un primer reactor para crear un primer producto bajo condiciones controladas de temperatura. El producto del primer reactor se alimenta en un segundo reactor para formar un segundo producto de reactor bajo condiciones no controladas, adiabáticas. Finalmente, toda trimetilamina no reaccionada en el segundo producto de reactor se retira para formar un producto final que comprende hidróxido de colina. Es posible utilizar reactores adicionales para la reacción de óxido de etileno y trimetilamina. |
