Phase Transfer Catalysis

As the industry strives to increase efficiency, improve process safety, and reduce environmental impact, Phase Transfer Catalysis has become recognized as a powerful tool for achieving these Phase transfer catalysisgoals. A phase-transfer catalyst or PTC is a catalyst that facilitates the migration of a reactant from one phase into another phase where reaction occurs. Phase-transfer catalysis is a special form of heterogeneous catalysis. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase in the absence of the phase-transfer catalyst. Phase-transfer catalysis refers to the acceleration of the reaction upon the addition of the phase-transfer catalyst.


Phase Transfer Catalysis with SACHEM PTC Products

SACHEM is an established world leader in developing Phase Transfer Catalysts (PTC) chemical compounds.  Our product palette of  Phase Transfer Catalysts (PTC) supports the catalytic process when conducting heterogeneous reactions where reagents are located in separate phases. The unique ability to dissolve in both aqueous and organic liquids makes SACHEM PTC compounds the catalyst of choice for most phase transfer catalysis applications.

Solvent choices for Phase Transfer Catalyzed Reactions:

  • Acetone
  • Ethylene Glycol
  • Hexane
  • Isobutanol
  • Methanol
  • Propylene Glycol

SACHEM PTC products provide enhanced reaction rates and yields, resulting in lower production, energy and waste costs. They enable the use of inexpensive inorganic bases (such as sodium hydroxide) and other reagents, and provide the ability to use less complex process equipment.

SACHEM offers a wide range of Phase Transfer Catalysts geared toward enabling successful implementation of a commercial Phase Transfer Catalysis process.

Whether you are designing a new process, or optimizing an existing PTC process, explore how SACHEM’s products and assistance can save time and money while increasing success in your reaction process.
