Product details

Uses and synthesis of Tetraethylammonium bromide powder

Tetraethylammonium bromide powder is white crystal. It absorbs moisture easily. Soluble in water, ethanol, chloroform and acetone, slightly soluble in benzene, solubility in water :2795 g/L (25°C). 10% aqueous solution has a pH of 6.5 and is heated to 95 ° C for 28 hours without pH change. It's stimulating. Tetraethylammonium bromide is used as a polarographic reagent and pesticide intermediate, sometimes for testing gold, iridium, palladium, rhodium, and ruthenium.

Production methodprocess of Tetraethylammonium bromide powder

7mL(5g,0.05mol) of triethylamine and 4mL(5.5g,0.05mol) of bromoethane and 20mL of,1, 2-dichloroethane or benzene were added to a 250mL three-mouth bottle with a return condensing tube and agitator. Reflux heating 1.5 ~ 2h. After the reaction liquid is cooled, the crystals are precipitated, filtered, washed twice with a small amount of 1, 2-dichloroethane or benzene, dried and stored in a dryer. Output Tetraethylammonium bromide 8 ~ 10g.
