Tetraethylammonium bromide 99% MIN 71-91-0 TEAB

Tetraethylammonium bromide Cas: 71-91-0, its English synonym: TETRAETHYLAMMONIUM BROMIDE; TEAB; TEA BROMIDE; Ammonium, tetraethyl-, bromide; Beparon; Bromethyl; Bromure de tetraethylammonium; tmd10; Tetraethylammonium bromide can be used as a Phase Transfer Catalyst for organic synthesis, a curing promoter for polymer polymerization, an organic electrolyte in the electronics industry, an oilfield chemical agent, a molecular sieve template agent, a phase change cold storage material, a high-performance liquid chromatography analysis reagent, a surfactant, descaling agent, adsorbent, oil displacement agent, etc. Tetraethylammonium bromide (TEAB, TEA bromide) is used as a source of tetraethylammonium ions in pharmacological and physiological studies, as well as in organic chemical synthesis. It can selectively block potassium ion channels.The production method of Tetraethylammonium bromide (TEAB, Bromide TEA): In a 250mL three necked bottle equipped with a reflux condenser and stirrer, 7mL (5g, 0.05mol) of triethylamine, 4mL (5.5g, 0.05mol) of bromoethane, and 20mL of 1,2-dichloroethane or benzene are added. Reflux heating for 1.5-2 hours. After cooling the reaction solution, crystals precipitate, filter, wash twice with a small amount of 1,2-dichloroethane or benzene, dry and store in a dryer. The yield is 8-10g.
