About Tetra Ethyl Phosphonium Hydroxide Aq. Solution

Tetra ethyl phosphonium hydroxide (TEPH) is a quaternary phosphonium salt that when dissolved in water becomes a colourless to light yellow liquid that is soluble in polar solvents such as ethanol and methanol. TEPH is prepared by the reaction of triethyl phosphine with water or aqueous sodium hydroxide. This chemical compound is commonly used in the preparation of various organophosphorus compounds. It is also used as a phase-transfer catalyst in chemical reactions that involve immiscible organic and aqueous phases. Proper protective equipment, such as gloves, safety glasses, and a respirator, should be worn when handling it.
