Tetrabutylphosphonium Hydroxide (TBPH) is an effective catalyst in a variety of reactions. It can be used as a strong organic base catalyst. Its basicity combined with its function as phase transfer catalyst makes it a versatile catalyst in many biphasic organic transitions used in the manufacture of polymers, pharmaceuticals, agrochemicals, flavors and fragrances. Also it finds use as (trans)esterification catalyst for the preparation of several monomers and polymers.
Tetrabutylphosphonium hydroxide (TBPH) is a quaternary phosphonium salt used as a phase transfer catalyst in the manufacture of pharmaceuticals, flavors and fragrances. It is also used as a cleaning agent for printed circuit boards and semiconductor wafers. It is a strong base.
