Tetrapropylammonium chloride is an organic compound with the chemical formula . It is a white, very hygroscopic crystalline solid. Tetrapropylammonium chloride is a quaternary ammonium salt. It consists of tetrapropylammonium cations and chloride anions .
Synthesis and properties Tetrapropylammonium chloride is synthesized by reaction between tripropylamine and 1-chloropropane.
The density of a concentrated aqueous solution of tetrapropylammonium chloride is less than that of a dilute solution at the same temperature.
The fully deuterated form of tetrapropylammonium chloride, , is also a white solid.
Uses Tetrapropylammonium chloride is used as antimicrobial agent. It is also widely used as a phase-transfer catalyst in organic synthesis, facilitating the transfer of reactants between immiscible phases. It is used to stabilize emulsions and enhance solubility of hydrophobic compounds in aqueous solutions.
