(3-CHLORO-2-HYDROXYPROPYL)TRIMETHYLAMMONIUM CHLORIDE - Preparation method
Open Data Verified Data
After adding a certain amount of concentrated hydrochloric acid to the reaction kettle, stir and add a trimethylamine aqueous solution. Control the reaction temperature to not exceed 30 ℃. After the reaction is completed, use trimethylamine to adjust the pH value of the solution to 7.5-8. The reaction formula is as follows: (CH:) N+HCl → → (CH:) N · HC Add the generated trimethylamine hydrochloride and water to the reaction pot, stir and heat to 40 ℃, add epichlorohydrin dropwise, control the temperature to 40-45 ℃, add it, and continue the insulation reaction for 2.5 hours. After the reaction is completed, concentrate, reflux with ethanol to dissolve, cool, crystallize, and centrifuge dry to obtain the finished product.
