Triphenylphosphite (CAS NO: 6999-19-5) is a colorless liquid-like organic compound used in organic synthesis. It is an organophosphorus compound with the formula C6H5O(P(C6H5)3)2. Triphenylphosphite is a white, crystalline solid that melts at 95°C and boils at 247°C. It is soluble in many organic solvents, but insoluble in water.
Triphenylphosphite is used as a catalytic reagent in the synthesis of polymers, pharmaceuticals, and other organic compounds. It is also used as a stabilizer for polyvinyl chloride, polyethylene, polypropylene and polystyrene. It is also used in the production of polyester resins, adhesives, and plasticizers.
Triphenylphosphite can also be used as a flame retardant in polyvinyl chloride, polystyrene, and polyester resins. It is also used in the manufacture of polyurethane foams, polysulfone resins, and coatings. It is also used in adhesives, sealants, and inks.
Triphenylphosphite is also used as an antioxidant in lubricating oils, fuels, and greases. It is also used in the manufacture of cosmetics, plastics, and food additives.
Triphenylphosphite is not toxic, but it can be irritating to the eyes and skin. It should be handled with care and appropriate protective clothing should be worn.
