What is TETRABUTYLPHOSPHONIUM HYDROXIDE?

The Uses of TETRABUTYLPHOSPHONIUM HYDROXIDE

Tetrabutylphosphonium Hydroxide (TBPH) is a quaternary phosphonium salt. It is an effective catalyst in a variety of reactions. It is a strong base that 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,polymers and a cleaning agent for printed circuit boards and semiconductor wafers.
Applications:

  • Glycidyl Ether Intermediates used in pharmaceutical applications.
  • Chemicals for Polymer Applications.

The Uses of TETRABUTYLPHOSPHONIUM HYDROXIDE

Tetrabutylphosphonium Hydroxide is a phase transfer catalyst for the etherification of thiosalicylic acid and analogs. Tetrabutylphosphonium Hydroxide is a pretreatment for rice husks that enhances enzymic and acid hydrolysis yields. Tetrabutylphosphonium Hydroxide is used in the synthesis of tetrabutylphosphonium carboxylate as a recyclable and highly selective catalysts for alcoholysis reaction of propylene oxide.
