Tetrabutylphosphonium chloride Chemical Properties, Uses, Production
Preparation
190.9 mL of P(C4H7)3 (154.7 g, 0.764 mol) was added to a flask equipped with a stirrer and a reflux condenser. The flask contained 100 mL of dried and degassed diethyl ether. 96.5 mL of butyl chloride (84.938 g, 0.918 mol) was added, and the solution was stirred under reflux for 2 weeks. This produced a very small amount of crystalline white product. To accelerate the reaction, the diethyl ether was stripped by distillation, and the reaction was continued under reflux for 1.5 days, during which the size of the product layer increased. The mixture was cooled to room temperature, forming a solid product layer, and 50 mL of diethyl ether (for storage) was added on top. The diethyl ether was then decanted, and the product was dissolved in 100 mL of acetone. After adding 1200 mL of diethyl ether, the product precipitated. The precipitate was filtered, washed with 3 × 150 mL of diethyl ether, and dried under vacuum to give a white powder of Tetrabutylphosphonium chloride (161.8 g, 0.680 mol, 89%).
Uses
Tetrabutylphosphonium Chloride functions as inhibitor of bovine serum amine oxidase.
Application
Tetrabutylphosphonium chloride is a green organic compound with a wide range of uses in catalysis, flame retardancy, solubility, ionic liquids and electroplating.
(1) As a catalyst for organic synthesis, it can be used to prepare alkyl bromides, 2-amino-4H-chromium derivatives, and methyl ester compounds.
(2) As a flame retardant additive for vinyl resins and chloroprene rubber, it is used to reduce the flammability and smoke emissions of these materials.
(3) As an ionic liquid, it provides a phosphorus source for microwave-driven synthesis of nickel phosphide nanoparticles, which are then used for efficient hydrogen evolution reactions.
(4) As an electroplating agent for various metals (such as copper, nickel, zinc, tin, lead, silver, gold, platinum, palladium and their alloys) to enhance the corrosion resistance and mechanical properties of metal coatings.
General Description
This product has been enhanced for catalytic efficiency.
