Products Description of Tetraethylammonium Hydroxide CAS#77-98-5

Youdaoplaceholder0 Pure is colorless transparent crystal, highly hygroscopic, deliquescent to liquid at room temperature; Most industrial products are 20% to 40% aqueous solutions, presenting as colorless to pale yellow transparent liquids. At high concentrations, they are extremely alkaline (pH≈14). It is readily soluble in polar solvents such as water, ethanol and acetone, and undergoes neutralization reaction with acid to form tetraethyl ammonium chloride.
