EC number: 213-650-7
CAS number: 998-30-1
Estimated value, no data available for temperature and pH
Water solubility (triethoxysilane): 5.6E+02 mg/l at 20°C (QSAR)
Water solubility (silanetriol): 7.9E+05 mg/l at 20°C (QSAR)
Water Solubility (ethanol): miscible at 20°C
The substance is hydrolytically unstable at pH 4, 7 and 9 (half-life
less than 12 hours). The hydrolysis half-life of the substance is
predicted to be 1 hr.
Predicted water solubilities of the substance and hydrolysis product are
5600 mg/l and 790000 mg/l respectively. These were predicted using an
appropriate QSAR and so are considered reliable. In practice, the
solubility of silanols is limited by their tendency to undergo
condensation reactions to form siloxane dimers, oligomers and polymers.
Ethanol is miscible with water (Riddick JA 1986)
