Physical and Chemical Characteristics of TMDSO

TMDSO (C4H14OSi2) presents itself as a colorless, transparent liquid. It possesses a molecular weight of approximately 134.33 g/mol and is characterized by the presence of two silicon-hydrogen (Si-H) bonds. These Si-H bonds are highly reactive and are the primary drivers behind TMDSO's extensive use in chemical synthesis and polymer modification. Key properties include:

  • Boiling Point: Approximately 70-71°C, indicating a moderate volatility.
  • Flash Point: Significantly low, around -26°C (-15°F), classifying it as a flammable liquid and requiring careful handling.
  • Reactivity with Water: Reacts with water to produce dimethylsilanol, dimethylsilanediol, and hydrogen gas, necessitating storage in dry conditions.
  • Moisture Sensitivity: Due to its reactivity with water, TMDSO is considered moisture sensitive.
  • Solubility: Soluble in organic solvents like hydrocarbons but insoluble in water.

These properties inform its handling, storage, and application methods, ensuring safety and efficacy in industrial settings.
