Related properties
The rigidity of three phenylphosphine oxide skeleton and the alkalinity of oxygen atoms all lead to crystallization. Compounds that are difficult to crystallize in other ways are especially effective for substances containing acidic hydrogen, such as phenol.
TPPO environmentally friendly flame retardant, mainly used for PET spinning flame retardant PPO/HIPS alloy, flame retardant, textile fabric, flame retardant, flame retardant polyethylene polystyrene foam, suitable for permanent flame retardant polyester modified, can function in organic synthesis intermediates, pharmaceutical intermediates, catalyst and extractant for fluorescent anti-counterfeiting powder.
