Triethylsilanol is a chemical compound from the group of organic silanols .

Extraction and presentation

Triethylsilanol can be obtained by hydrolysis of triethylfluorosilane (Et ₃ SiF).

{\ displaystyle {\ ce {Et3SiF + H2O -> Et3SiOH + HF}}}

properties

Triethylsilanol is a colorless liquid with a flash point of 57 ° C.

More recent studies on trimethylsilanol and triethylsilanol show that they are highly effective and have a significantly better effect than the corresponding alcohols tert-butanol and 3-ethylpentan-3-ol as antimicrobial substances against E. coli bacteria and Staphylococcus aureus .
