The chemical properties and storage methods of Phosphotrimethylphenol (or Trimethylphenyl Phosphate , often abbreviated as TMPP) are as follows: Chemical Properties Molecular Structure and Formula : TMPP belongs to the category of phosphate esters, with a chemical formula of (CH3C6H4O)3P=O or C21H21O3P. It exists as a colorless or light yellow transparent oily liquid, with a relative density of approximately 1.162 (at 25°C). Physical State and Solubility : TMPP is an oil-like liquid at room temperature. It is insoluble in water but soluble in organic solvents such as ethanol, ether, chloroform, benzene, and glacial acetic acid. Thermal Stability : TMPP has a high boiling point, typically around 410°C (with partial decomposition). It remains stable under normal conditions and does not burn. Toxicity : TMPP is toxic, especially its ortho-isomer, which is approximately 10 times more toxic than other isomers. Storage Methods Storage Environment : TMPP should be stored in a cool, well-...
