26576-85-2 - Reference Information
| Use | 1-butyl-3-methylpyridine bromide is a 1-alkyl-3-alkylpyridinium halide compound. 1-alkyl-3-alkylpyridinium halides can be used as bromine complexing agents (bromine-complexingagent) in aqueous zinc bromide solutions used in zinc/bromine rechargeable batteries (I. e., in both zinc/bromine flow batteries with membranes and zinc/bromine flow batteries without membranes). It has been found that a complex formed by using 1-alkyl-3-methyl-pyridinium bromide or a mixture thereof does not solidify at temperatures as low as 0°C or even − 5°C, thereby maintaining the fluidity of electrolyte solutions having different compositions corresponding to different states of charge of the battery over a wide operating temperature range. |
| preparation | double-sided reactor equipped with magnetic stirrer, condenser, thermowell and drip funnel. The reactor was purged with nitrogen during the entire step. 3-methylpyridine (465g) was fed to the reactor and the reactor was heated to 79°C. Then, n-butane bromide (718g) was added dropwise for 4 hours. The reaction mixture was heated at 80°C for 0.5 hours. DIW(500mL) was added; the mixture was cooled and volatiles evaporated in a rotary evaporator. Additional DIW(500g) was added and the mixture was re-evaporated. Add DIW to supplement (correct) dilution. Final product 1-butyl-3-methylpyridine bromide, 1431g,77.5 wt% (silver titration); yield, 96.5%. |
