Product Introduction Chemical Formula: C18H15OP Molecular Weight: 278.28 CAS Number: 791-28-6 Chemical Name: Triphenylphosphine oxide; Triphenylphosphine oxide; Triphenylphosphine oxide (TPPO) is a pure white crystalline powder that is soluble in alcohols and benzene. Melting point: 154-158C (427-429K). Boiling point: 360C Flash point: 180C (633K) Molecular structure: Ph3PO has a tetrahedral structure similar to POCl3. Appearance: Pure white powder, soluble in alcohol and benzene, with irritant properties. The rigidity of the triphenylphosphine oxide skeleton and the alkalinity of the oxygen atom, which can affect the properties of organic synthesis intermediates, can induce the crystallization of compounds that are difficult to crystallize by other methods. It is particularly effective for substances containing acidic hydrogen, such as phenols. TPPO environmentally friendly flame retardant is mainly used for PET spinning flame retardant, PPO/HIPS alloy flame retardant, textile fabric flame retardant, polyethylene, polystyrene foam flame retardant, suitable for permanent flame retardant modification of polyester, can act as an organic synthesis intermediate, pharmaceutical intermediate and extractant, and is used for fluorescent anti-counterfeiting powder, etc. Packaging: 25KG/bag Storage and transportation: Handle with care, seal and store, do not get damp.
